Is your power bank blinking but not charging? Here’s what to do

Power banks can be real lifesavers, but sometimes they can give us headaches too. One of the most common problems with portable chargers is that their lights might blink in a specific pattern, which is not easy to understand.

Erratic light blinking can also be associated with another issue, such as the power bank not charging. In this article, we’ll be exploring some of the most common causes and solutions.

The LED Indicator Lights and Their Meaning

For a visual explanation, check out my video on this subject:

The average power bank has a set of LED lights (usually 4) that indicate the level of charge in the battery, but other important information about the power bank’s state as well.

When you connect a power bank to a power outlet to recharge it, one of the LED lights will usually blink, indicating that the power bank is taking up the charge. As you can see in the image above, the pattern in which the LEDs are light up signifies the level of charge in the power bank:

  • One LED is equivalent to a charge level of 0%-25%
  • Two LEDs are equivalent to a charge level of 25%-50%
  • Three LEDs are equivalent to a charge level of 50%-75%
  • Four LEDs are equivalent to a charge level of 75-100%.

As the power bank charges usually one LED light blinks, the last one in the series. For example, if there are 3 LEDs on, then only the 3rd one will blink until the next charging level is reached and then the 4th LED will start blinking. Once the power bank has reached a 100% charge level, all the LED lights will be constantly on, without any one of them blinking, until you unplug the device from the charger. And as you start charging another device using your power bank, the LED blinking pattern will resume designating the transfer of electricity.

Furthermore, while the power bank is not being charged, if you press the power button, all the LED lights will be briefly turned on, according to the charge level of the battery.

Other Functions the LED Lights Can Have

The battery charge level of the power bank is just one function of the LED lights, albeit the most common one. But the LED lights can also communicate other things as well. Here’s a list of some of the most common issues that they might signal:

  • Charging Indication: Some power banks may use blinking LEDs to indicate charging status. For instance, a light might blink while the power bank is charging and then become steady once the device is fully charged.
  • Fast Charging Indication: If the power bank supports fast charging (like Qualcomm’s Quick Charge or Power Delivery), the LEDs might change color (such as from white to green) to indicate when fast charging is active.
  • Error Indication: Some power banks use LED lights to indicate problems. For instance, if all lights are flashing simultaneously, it might be a sign that there’s an error, like a short circuit or an overcharging problem.
  • Power Bank Status: Beyond charging, some power banks use LED lights to indicate the power bank’s status. A light might come on when it’s successfully connected to a device or flash to show it’s in standby mode.
  • Battery Health: In some advanced models, different blinking patterns or colors might be used to indicate the health of the battery, warning the user if the battery performance is degrading and needs to be replaced.

Since these signals can vary greatly between different models and manufacturers, it’s important to refer to the user manual that came with the power bank for accurate information. The manual should provide a clear explanation of what each LED light or pattern signifies for that specific model.

What a Blinking Red Light Might Indicate

We reserved a dedicated section for a blinking red light because it’s a rather important one. Because there’s no universal power bank language, it can mean different things depending on each model. Here are the most common interpretations of the red light blinking on a portable charger:

  • Battery Low: The most common reason for a blinking red light is that the power bank’s battery is almost empty. This typically signals that the device needs to be recharged immediately.
  • Error State: A flashing red light could also indicate a problem or error with the power bank, such as a charging fault, a short circuit, or an issue with the internal components.
  • Overheating: Some power banks have a built-in safety feature that triggers a blinking red light when the device is overheating. This can occur if the power bank has been in use for an extended period if it’s charging a device while being charged itself, or if it’s been left in a hot environment.
  • Overload: If a device that draws more power than the power bank can provide is connected, the power bank might blink a red light to signal that it’s overloaded and can’t charge the device.

Again, each power bank is different, so for the exact interpretation of a red LED blinking on your power bank, please consult the user manual. You can also get in touch with me via the comment section below and I’ll do my best to figure it out.

LED Lights Blinking But the Power Bank Won’t Charge

In some cases, you might notice that the power bank is not charging despite being plugged into a power source, with the LED indicator lights flashing.

It may happen that after waiting several hours, or even a day, your power bank doesn’t charge fully. It may only charge partially, or not at all. You may wonder if this signifies a complete failure of your power bank, or if it’s just a minor issue.

A multitude of factors can contribute to such a scenario. To help you understand what might be going wrong, we’ve compiled the following checklist that you can use to troubleshoot and diagnose the issue.

Possible Causes and Troubleshooting Checklist

In order to pinpoint the exact issue your portable charge might have for not charging as expected, you should check different possible failure points. It may be that the problem is a very minor one that’s easy and quick to fix. But it may also be something more serious that might not even be fixable. Here’s what to look for:

Reset the Power Bank

Some power banks come with a reset function. In case your power bank has this function, use it. This may clear any temporary issues that are stopping the power bank from charging. The method to reset differs by brand and model, so consult your power bank’s manual for specific instructions. This usually fixes the majority of charging issues. If it doesn’t work, please proceed with the steps below.

Check if Power Cables Are Properly Connected

An insufficiently inserted power cable could be the source of the problem, resulting in an unstable connection. Verify that both ends of the plug securely fit into their respective charging ports.

Additionally, keep an eye out for debris (like dust, sand, lint, or dirt) that might be lodged in the charging port. This could disrupt the connection, so ensure the port is clean, but do so gently to avoid damaging any components.

Use a Different Charging Cable

If the connections are secure but your power bank still isn’t charging, the power cable itself might be the issue. Some cables are of lower quality, impacting the charging rate.

Also, if the cable doesn’t support the fast charging technology that your power bank requires, it could result in undercharging. In this case, trying a different power cable might resolve the issue. As a general rule, try to use the original cables the portable charger came with, unless they are visibly damaged.

Sometimes even the slightest pinch can damage charging cables. I accidentally squished numerous charging cables with the foot of my stool as I was working at my desk. These things happen almost on a daily basis, but we seldom think that they might have an impact on the cables themselves.

Don’t Charge Your Power Bank Via a Laptop’s USB Port

When charging your power bank, it’s crucial to use a main electric power outlet rather than a laptop’s USB port. The latter usually only output around 0.5 A, which typically isn’t enough to efficiently charge a power bank.

your, power, bank, blinking, charging

This also holds true for USB hubs that don’t have fast charging protocols. A lot of time people are not aware that different power sources have different power outputs, so they expect the same results regardless of what they’re using. But simply charging a power bank via a low-powered laptop’s USB port can add up to 10 hours to the total charging time, especially if it’s a high-capacity power bank.

Experiment With a Different Wall Charger

The adaptor you’re using could be faulty or delivering too low an output for the power bank to charge. Consider trying a different adaptor. If this resolves the issue, it’s a clear sign that your original adaptor is faulty and needs replacing.

Also, please make sure that the chargers are compatible with the power bank when it comes to charging technologies. For example, you’ll reach the best results if both the charger and power bank feature the PD (Power Delivery) protocol.

Test with Different Devices

Connect different devices to the power bank to rule out the possibility that the issue is with the device you’re trying to charge and not the power bank itself. One common issue is that people try to charge low-power devices such as fitness bracelets, Bluetooth headphones, or smartwatches using the regular power mode. In order to charge these devices you need to activate the trickle charging mode (also known as low current charging). Please refer to your user manual on how to do that, since different models have different ways to turn trickle charging on.

Another important mention is that not all power banks come with a trickle charging feature. So if your power bank can successfully charge a smartphone for example, but will not charge a low-power device and the user manual doesn’t mention anything about trickle charging, then the power bank model that you have doesn’t support this feature.

Check for Physical Damage

Inspect your power bank for any signs of physical damage. If it has been dropped or exposed to extreme conditions, there might be internal damage that is not immediately apparent. Another important clue to look for is a swollen or bulging battery. This might not be immediately obvious if it’s in the early stages, but the power bank might be slightly rounded and easily rocking side-to-side. The casing edges might even come apart slightly or very obviously like in the example below:

All these symptoms are pointing to an overcharged battery that has expanded. In this stage Li-ion batteries can be dangerous, read more about it here.

Troubleshooting Did Not Solve the Issue?

If you followed the suggested troubleshooting list and the problem still persists then there are two main possibilities:

  • There is an internal circuitry problem. This can have many causes from improper usage and/or storage to a manufacturing defect.
  • The battery has reached the end of its life. This would be the case if you had the power bank for a while now and have charged and discharged it hundreds of times. Generally speaking, Li-ion batteries start to lose about 20% of capacity after the first 500 charge/discharge cycles and will keep degrading as they’re being used. At around 2500 cycles you can expect the battery to be completely unusable. Please bear in mind that these are just some rough estimations though, the actual battery-depleting process can be shorter or longer based on a wide array of factors.

Here’s What to Do if Your Portable Charger’s Battery Died

If you’re sure that the main issue is a dead or faulty battery, then here’s the best plan of action to take:

  • Check your warranty. If your power bank is within the warranty limit, then get in touch with the store that you bought it from for further information. In some cases, you might get a replacement product, a free repair, or even a refund.
  • Get in touch with customer support. Larger manufacturers such as Anker, RAVPower, or Aukey have dedicated support teams that might be able to help you with the issue. They might be able to help even if your warranty is expired. However, less popular manufacturers such as Juice, BlackWeb, or Mophie don’t have such extensive client support systems in place, so getting in touch with a representative might be somewhat more difficult. But even so, it’s would still be worth trying to get in touch with a company representative.
  • Have the power bank serviced by an electronics repair shop. If you have such a shop nearby it’s always a good idea to take the power bank in for a checkup. A professional can quickly pinpoint the problem, which sometimes can be very trivial. It happened to me once when I thought that my smartphone was dead because it wasn’t charging anymore, so I had it checked. It turns out the charging cable I was using did not work and the phone was completely fine. Had I followed the troubleshooting suggestions above, I would have discovered the issue myself, but in this case, the friendly people at the service shop quickly figured out what was wrong.
  • Safely dispose of the defective device. If nothing else worked and the power bank is unsalvageable, the best thing to do is to safely dispose of it. The only secure way to do that is to take it to a designated collection point for small electronics and/or batteries. This way you can ensure the battery will get recycled and will not end up in a landfill where it would potentially release toxic substances or even start garbage fires.

Alternatives to LED Lights on Power Banks

As an outro, I wanted to point out that LEDs are not the only option when it comes to power banks. In fact, they’re the most prevalent solution out there because it’s the cheapest and simplest one to create. So the majority of the manufacturers go with this one out of commodity. But there are other options out there as well, which I would recommend over the classic LED lights.

LCD Display Power Banks

Some power banks have an LCD (Liquid Crystal Display) screen which can provide a range of information. This could include the exact percentage of battery charge left, input/output voltage, charging current, fast charging status, or even error messages. An LCD display provides more precise information than LED lights.

Digital LED Display Power Banks

These displays work similarly to an LCD screen but use LED technology to provide numerical or alphanumeric information about the charge level, usually in terms of a percentage.

Wrap-up

Blinking lights on a power bank can have a lot of different meanings. They generally refer to the charging state of the battery, but they can also communicate different issues. Since not all power banks are the same, it’s always a good idea to check the user manual for the exact model you have. In case you lost it, you can generally find it online by doing a dedicated search.

If that doesn’t work, hopefully, this article can help you out by giving you some troubleshooting ideas and some general suggestions. In case you have some specific questions or requests, don’t hesitate to reach me in the Комментарии и мнения владельцев below or via my YouTube channel.

Juice to go: The best portable chargers

Whether you need instant Instagram access while camping or you’ve drained your phone with a day of Pokémon hunting, portable battery packs can be your best friend. But with so many of them out there, finding the right one can be a daunting task. From.sized boosters to beasts that power everything under the sun to those powered by the sun, we’ve gathered some of our favorite portable chargers.

Jackery Bar

Capacity: 6,000 mAhOutput: 5 V, 2.1 ASize: 1.8 x 3.8 x 0.9 in (4.6 x 9.7 x 2.3 cm)Weight: 5.3 oz (150 g) Price: 13

At the low end of the scale, the Jackery Bar forgoes fancy bells and whistles for a reliable, compact and inexpensive charger that can sit in a bag and provide a quick top-up to a phone at the end of the day. The 6,000 mAh battery is enough to fully charge a Samsung Galaxy S7 or an iPhone 7 twice over, and for that price it’s perfect for those who sometimes just need to squeeze a little more out of their phones.

Flux Portable Charger

Capacity: 4,000 mAhOutput: 5 V, 1 A/2.1 ASize: 4.3 x 2.5 x 0.3 in (10.8 x 6.3 x 0.8 cm)Weight: 3.1 oz (88 g)Price: 30

While you might only get one and a bit charges out of the Flux Portable Charger, it’s designed to be as compact as possible. Where the Jackery Bar suits a purse or handbag, the Flux is thin enough to slip into a The two ports – a micro USB for Android and a Lightning for iOS – are on little arms that tuck away inside the device.

Lumsing Power Bank

Capacity: 10,400 mAhOutput: 5 V, 1 A/ 2.1 ASize: 5.4 x 2.3 x 0.8 in (13.7 x 5.8 x 2 cm)Weight: 8.5 oz (241 g)Price: 17

Another bag-sized device, the Lumsing Power Bank is a little heftier than others, but that’s because it’s packing more power. A battery boasting over 10,000 mAh lets it fully charge an iPhone 7 or Galaxy S7 three times, handy for a weekend away or back-to-back long haul flights.

Juno Jumper

Capacity: 6,000 mAhOutput: 5 V, 2.1 A (USB), 12 V, 150. 300 A (jumper cables)Size: 5.5 x 3 x 0.6 in (13.9 x 7.5 x 1.5 cm)Weight: 7 oz (198 g)Price: 99

At first glance, the Juno Jumper is a fairly standard portable charger. The 2.1 A USB port will charge a device fairly fast, with enough juice to do so a couple times over. But the real kicker? It can recharge your car, too. Hooking up the included jumper cables, the Juno ups the output to 12 V at 300 A, which the company says is enough to jumpstart almost all 4- and 6-cylinder engines.

Mophie powerstation XXL

Capacity: 20,000 mAh Output: 2.1 ASize: 3.6 x 6.1 x 0.8 in (9.2 x 15.5 x 2 cm)Weight: 15.1 oz (428 g)Price: 99

While the Mophie powerstation XXL is relatively bulky, it also gains in capacity. It earns its place in a bag or backpack with a beefy 20,000 mAh battery, which is enough to charge some devices up to seven times. Three USB ports allow several devices to be powered at once, and the user can prioritize which ones charge up faster.

HP Powerup Backpack

Capacity: 22,000 mAh Output: 5 V, 2 A/2.4 A (USB), 19.5 V, 3.33 A (laptop cable)Size: 19.7 x 13 x 6.3 in (50 x 33 x 16 cm)Weight: 4.2 lb (1.9 kg)Price: 199

Bucking the smaller-is-better trend, the HP Powerup Backpack goes large to not only power your devices, but carry them, too. The huge 22,000 mAh battery is housed inside, while included cables are threaded through to other s to charge two micro USB devices and a HP laptop with 4.5 mm and 7.4 mm barrel connectors. Built-in heat sensors keep it from getting too warm, and it comes with a rain slicker to keep valuables protected from the elements.

BioLite KettleCharge

Capacity: 1,250 mAhOutput: 10 W, 5 V, 2 ASize: 7.3 in (18.6 cm) highWeight: 2 lb (0.9 kg)Price: 79

A 1,250 mAh battery seems a little piddly, providing less than a full charge to most current phones, but the difference here is the method. Using a thermoelectric generator, the BioLite KettleCharge harnesses the power of boiling water to create energy, meaning you can top up your phone while making your morning cup of coffee. This is one to take camping when you’re off the grid and may occasionally need to check your email or the weather forecast.

Another off-the-grid solution, the Solartab plugs into the sun to keep your devices powered up. Its battery is a respectable 13,000 mAh, so it can charge some phones up to ten times over. While it may be dependent on the fickle moods of the weather, the internal battery can store the energy for long periods, letting you save it for … well, a rainy day.

ZeroHour BB

Capacity: 10,200 mAhOutput: 1.5 A/2.1 ASize: 7. 3 x 2.3 in (18.5 x 5.8 cm)Price: 125

RAVPower Travel Charger

Capacity: 27,000 mAhOutput: 100 W (AC), 5 V/2.4 A (USB x 2), 5 V/3 A (USB Type-C)Size: 5.3 x 6.9 x 1.4 in (13.4 x 17.5 x 3.6 cm)Weight: 1.9 lb (0.9 kg)Price: 150

At the far end of the scale, the RAVPower Travel Charger pushes the boundaries of the definition of portable, but for those who need to power a whole studio’s worth of devices on the go, it may just do the trick. A gigantic 27,000 mAh battery feeds into a good range of ports, with two standard USB outlets, a USB Type-C and, perhaps the clincher, a 100 W AC outlet, meaning just about anything that plugs into a wall can plug into the RAVPower Travel Charger.

Review of Lumsing 10400mah Portable Power Bank

power is needed for our mobile devices and today I have another portable battery pack for review from our friends over at Lumsing. Today I have a 10400mAh portable battery pack or power bank that features two USB ports that can charge tablets or phones or both at the same time or virtually anything else that charges via USB. The 10400mAh capacity of the battery will allow you to charge you devices multiple times so it’s a great power pack for just a day or even a weekend on the go and it will make sure you’ve got power when you need it most. Read on to learn more.

Unboxing

We’ll start off with a video unboxing for you:

The packaging is certainly different, it’s brown box with what looks almost like a sketch of the battery on the front and then specs and other info listed on the back. The box has a rope or cord style handle on it which I found interesting.

Once you get everything unpacked you’ll find the battery, USB cable, cloth carrying bag, user guide and Lumsing power user program pamphlet. The Power User Program is so customers can join and possibly test new products before they come to market, a testing program essentially. you have to go to their website and fill out the form and they’ll let you know if you’re picked. A nice idea I guess.

The carrying bag is cloth style with drawstring and the USB cable has a microUSB connection on one end and a standard USB connector on the other. The cloth bag isn’t exactly protective like a hard case would be but it should keep the battery clean and free from scratches and scuffs while you’re transporting it.

The name or description on Amazon says ‘Lumsing 10400mah Harmonica Style Portable Power Bank External Battery Pack Backup Charger’ and yes it is kind of shaped like a harmonica, a very nice looking harmonica for sure. The dimensions are 5.43x 2.35 x 0.86 inches and on the top you’ll find a glossy black finish with a brushed aluminum Band across the bottom with the Lumsing logo.

It weighs in at a little over 12 ounces and it looks great and it feels well made. It has a solid construction with a nice design over all.

On the left side you’ll find a microUSB port that’s labeled ‘IN’, this is for charging the Lumsing battery with the supplied cable. The right side of the battery is just plain, nothing there, so it’s not pictured.

your, power, bank, blinking, charging

On the Front edge is where you’ll find the two USB charging ports that are labeled Out 1A and Out 2.1a. There’s four LED indicators that will light up blue, they indicate battery charge or capacity levels and are 25% each. There’s also a silver oval shaped button to power the battery on to begin charging.

The glossy back from the front continues all the way around to the back and here you’ll also find the basic specs listed as well.

The black looks nice but I found it attracts dust and fingerprints like a magnet and it quickly will get smudged and lose its glossy shine.

Usage and Testing

The first thing I did was charge the battery with the supplied USB cable and it didn’t take long as it was already at about 75% capacity when it arrived to me. The LEDs will light up and blink to let you know it’s charging and then they’ll fill up and turn solid when charged. Since the battery was already at about 75%, only one LED was blinking for me, but if it was lower more LEDs would blink to and turn solid as the battery filled up.

To test the battery I charged a few things like my HTC One cellphone, Motorola Bluetooth GPS and my Joby Blade rechargeable flashlight. I charged all of them to full and when done with all three I still had about 75% capacity on the Lumsing. Yes all three of the devices weren’t quite dead, but they were used. The phone was about 75% capacity, and I’m not sure about the GPS or the flashlight as neither have a battery level indicator on them. The use the battery you need to press the button to begin charging your devices, some batteries start charging automatically, but with the Lumsing you must press the button.

As far as charging speed, it seemed the same as if I was charging from the USB ports on my computer, so no real complaints there as I charge pretty much everything from my computer since it’s readily available. Yes you can charge two devices at the same time if you want, but it will drain the battery faster obviously, but it’s to know you can do it if need be.

The Lumsing battery does include overcharge, overvoltage, overcurrent, and short circuit protection to make sure your devices will be safe.

I should note that this Lumsing battery will not charge my Playstation Vita. I’ve found this to be common among the majority of these portable battery packs, not sure why, it should but yet it doesn’t.

I do feel I have to mention the size of this battery, it’s small. I have the Eagletech Neptor 10000mAh battery and I pulled it out for comparison and the Lumsing is smaller in physical size but yet the Lumsing has a larger battery at 10400mAh. The Lumsing is slightly thinner in height and width. Both batteries have two USB ports on them so they are similar in that respect but the Lumsing is smaller making it more portable and personally I think it looks nicer as well.

Conclusion

The Lumsing 10400mAh is a handy battery to have for sure, you can keep your phone an tablet charged while on the go and virtually anything else that charges via USB so you can always power while you’re out and about.

Aesthetically the Lumsing 10400mAh battery just looks great, it has a glossy black finish with silver accents that just makes for a nice presentation overall. Lumsing included a cloth carrying bag to help protect it while you’re on the go.

The battery is small enough to fit in your hand or making it very portable, you can of course just toss it in your bag and go.

The Lumsing 10400mAh battery does let you charge two devices at once if need be which can come in handy as we all have more than one rechargeable device.

The only real complaint I could have about the Lumsing 10400mAh battery is aesthetic, the glossy black finish really picks up fingerprints and smudges from your hands and fingers making it not exactly nice looking anymore. They should have included a cleaning cloth surely as it really needs one, but you could just use the outside of the cloth carrying bag if you wanted to.

At the time of this review the Lumsing 10400mAh battery was listed at 19.99 and it’s well worth it for that price. If you’re looking for portable power then I can recommend this battery pack to you as it will provide plenty of power for multiple devices.

Pros: Inexpensive Small and portable Charges tablets and phones Large capacity battery Aesthetically pleasing Simple to use

Cons:.Glossy black collects dust and fingerprints

Lumsing 11,000mAh Power Bank Review!

The Lumsing Power Bank is a reasonably priced solution to the problem which a lot of people face of not having removable batteries from their phones. If you have an iPhone or a HTC One or something like this something which would suit you down to the ground!

As far as power banks go there’s a lot of choice on the market; you can go for super cheap solutions which will give you a slight top up if your phone needs one half-way through the day, or you can go for something slightly more expensive like this Lumsing which promises to give you multiple charges from it’s larger battery.

Performance: Obviously the main thing with this sort of device is how long it lasts and whether or not it actually comes through on the promise of recharging your devices. With an 11,000 mAh capacity theoretically this battery pack could charge my LG G2, with it’s 3,000 mAh battery, three times with a little bit of juice to spare. As we know though, theory and practice are not the same things. People normally say you should expect to get about 70% of the total capacity out of the actual battery bank, so you can think of this as a 7700mAh unit, which is actually quite respectable. With that in mind, it’s good to know that the actual transferable capacity of this device is probably somewhere close to the target 7700 mAh. We managed to get 2 full charges of the LG G2 and there was enough to top the phone up to 60% again, so the performance was slightly better than we would have expected, which is fantastic given the price!

It’s also nice to know that you can simultaneously charge the power bank and charge something else at the same time, so if you only have one charger then you’re still good to power your battery pack and phone or tablet at the same time.

Another nice addition is that the five USB ports which you can charge from all offer varying outputs. So you have a 1.3A output for your Galaxy Tab, 2.1A for the iPad line, 1A for your typical mobile phone and then 0.5A for a smaller battery bank or perhaps an MP3 player. It’s great because it adds an extra bit of versatility to your power needs and we’re sure you could give charging your laptop a go from this if you really needed an extra bit of juice too!

Some people have asked if you can use the power bank while it is charging and you definitely can, it works really nicely!

Some of you out there might have been stung by cheap battery banks before and thankfully with this one we have no concerns over the quality of it. The bank feels nice and dense, which if nothing else is reassuring. The plastic which Lumsing has used feels nice and sturdy. it reminds us of the plastic which LG employed on their G2 and which Samsung have used on their older generations of the Galaxy S.

Ease of use: You might be asking yourself why we bothered to talk about ease of use. surely you just plug it in and go. To a certain extent you do, but with some battery banks you have to flick switches for different ports and it can get a bit messy. The Lumsing on the other hand chooses to keep things simple. You get one off and on button. Press it once and it shows you how much charge there is and turns the whole unit on. Press it again and everything will shut off. It’s simple and elegant and that’s the sort of no thrills performance you want from this sort of accessory.

Extras: In the box you get a plethora of connection options; there seems to be an adaptor for almost every type of proprietary charging jack which we could think of as you can see to the right.

The little bag which Lumsing threw into the box is a nice touch and although it’s undoubtedly cheap and cheerful, it’s actually a good extra layer of protection if you throw the unit into your bag. You know that people often say it’s the little things which matter, we definitely think helps when it comes to things like this.

It’s also worth bearing in mind that this power bank comes with a 12 month warranty and that promise of longevity is also so a sign of Lumsing’s confidence in their product which is great to know as a buyer. Especially as most phone companies recommend changing the battery in your mobile phone every six months if that’s an option!

So is the Lumsing power bank worth your hard earned cash? In a word, yes. It does exactly what it says on the tin, it’s solidly build, Lumsing has convinced us that they’re offering a good quality product and as far as we’re concerned you shouldn’t be disappointed with what you’re buying.
