FAQs About The Best Power Banks

How much time does a power bank take to charge fully?

Typically, a power bank will be fully charged in 4-6 hours. However, this also depends on the capacity and charging technology of the power bank. A powerbank with higher capacity may take 7-9 hours to be fully charged. On the other hand, powerbanks with the same capacity and multi-input charging technology take less time (4-5 hours).

Why do power banks take so long to charge?

Because power banks have large batteries, they take longer to charge. However, this may also indicate that there is a problem with your power bank’s charger. Powerbanks with relatively high capacity take longer to charge than a normal charger.

How can I charge my power bank faster?

You can use a charger with a higher amperage to charge your power bank faster. However, it is important to check the compatibility of the charger as it may damage the power bank. This information can be found in the product manual and on the manufacturer’s website.

Do power banks lose charge over time?

Yes, power banks lose charge over time, even when not in use. This is because they use lithium-ion batteries, which have a natural self-discharge rate. The rate of self-discharge depends on several factors, such as the quality of the battery and its storage conditions, but generally, most power banks will lose about 5-10% of their charge per month.

Is a larger power bank more advantageous?

The larger the battery capacity of your power bank, the longer it can power a device without needing to be recharged. It’s more advantageous if you have to charge multiple devices at a time. However, if portability or budget is a concern, a smaller power bank may be a better choice.

Do power banks harm the battery life of a phone?

Power banks do not harm the battery life of a phone. In fact, using a power bank can actually help to prolong the battery life of your phone by reducing the number of charge cycles it goes through. However, if you charge it with the wrong voltage, the life of your smartphone’s battery can be significantly shortened. It is important that you check the compatibility of the powerbank before using it to charge your phone.

Can laptops be charged by some Power Banks?

Yes, newer laptops can be charged with some power banks, provided the power bank supports laptop charging and has sufficient capacity. Laptops typically require more power than smartphones or tablets, so you’ll need a power bank with a high capacity and wattage output to charge a laptop.

Are Power Banks safe to use?

Yes, power banks are safe to use as long as they are used and handled properly. It is important to read the instructions and check compatibility with your product to avoid damaging the power bank or your device.

How to Use a Power Bank: Here’s Everything You Need to Know

You know that anxious feeling when the “low battery” notification pops up on your screen? There’s something about it that can send your mind into a tailspin. Even worse, sometimes you don’t have your charger, and you’re nowhere near an outlet! Luckily, there’s a handy tool out there to keep you fully charged: the power bank. If you’re looking to learn the basics of power banks, you’ve come to the right place. Let’s get right into it!

How to Charge a Power Bank Top

Charging a power bank is pretty straightforward, especially since most of them come with instruction manuals. However, if yours didn’t come with one, you can still charge it without breaking a sweat!

Here is the best way to charge a power bank:

  • Attach the cable to the power bank.
  • Connect the other side of the cable to your power source.
  • Your power bank should begin charging.
  • Once charged, unplug the power bank from the wall and your phone.
  • Step 1: Attach the Cable Attach the cable that came with your power bank to the device itself. Most of the time, the port that connects to your power bank is a micro USB.
  • Step 2: Plug Into Power Source Next, plug in the other side of the cable (usually a standard USB) into your wall plug or your computer. Some wall outlets even have USB ports built in, so if you have one of those nearby, you won’t need a wall adapter!
  • Step 3: Start Charging Your power bank should start charging. If it has an indicator light, keep a close eye on it. Once it is fully charged, all the indicator lights will illuminate.
  • Step 4: Unplug the Charger Unplug the charger from the wall or your computer once all indicator lights are illuminated.

How Often Should You Charge a Power Bank? Top

A general rule of thumb is that the more you charge your power bank, the shorter the lifespan of the device. You should charge your power bank only as often as is necessary. If you use your power bank sparingly, at least charge it once every 3 months to keep the battery active.

Can I Use My Phone While Charging? Top

There shouldn’t be any harm in using your cell phone while it is charging. You may notice your phone getting a bit warm, but this is expected. It’s worth noting, however, that using your phone while it is charging may not result in a 100% charged battery since you are actively using the power source before the charge is complete. If you want your cell phone to be fully charged, it’s best to leave it alone while it powers up!

Why Do Some Power Banks Take Longer to Charge? Top

Some power banks take longer to charge because larger batteries have a bigger capacity to store energy. For example, a high capacity power bank with 20,000 mAh can take up to 40 hours to charge fully. Smaller power banks with 4,000 mAh may only take a couple hours to charge.

Think of it like a shot glass versus a tall drinking glass. It’s going to take a lot longer for a drinking glass to fill with water than it will for the shot glass!

How Long Should You Charge a Power Bank? Top

You should only charge your power bank for the amount of time it takes for it to get a full battery. Once the device is fully charged, you should unplug it from the power source. You can check the user manual to find out how your power bank indicates it has been fully charged, but most of them have some sort of light that shows the amount of power left in the battery.

The amount of time it takes for a power bank to reach its full capacity varies depending on the type. A heavy-duty power bank will take longer to charge than a smaller one. Generally speaking, it takes between 1 to 2 hours for a power bank to become fully charged!

Did You Know?

There are super powerful power banks on the market that allow you to power larger devices like televisions, curling irons, and oscillating fans!

Can I Charge My Power Bank Overnight? Top

You should avoid charging your power bank overnight whenever possible. It is unlikely to cause significant damage, but there is still a chance it could reduce the lifespan of your battery over time.

For lower-quality power banks, leaving your power bank plugged in after it is fully charged can cause overheating, especially if they are left to charge in direct sunlight. The safest option is to always unplug your power bank once it has reached full capacity!

How Can You Make Your Phone Charge Faster? Top

If you ever find yourself in need of a quick battery charge for your smartphone, there are a few steps you can take to make your phone charge faster. Always make sure your charging cables are plugged all the way in and your power bank has enough power to charge your phone.

Here are some tips to make your phone charge faster:

  • Turn on airplane mode
  • Don’t use your phone while charging
  • Turn your phone off
  • Use a high-capacity power bank
  • Don’t use a wireless charger

Turn on Airplane Mode

Putting your phone on airplane mode is a surefire way to reduce charging time. This is because the setting turns off your phone’s Wi-Fi, Bluetooth, and cellular capabilities, which are all settings that drain your power! When your device is on airplane mode, it’s consuming less power, which makes for a quicker charge.

Don’t Use Your Phone While Charging

Using your phone while it’s charging is going to increase the amount of time it takes for your battery to be fully powered. It may be difficult to resist the urge to send that text message or check Instagram, but it’s worth the sacrifice if you want your phone to be fully charged!

Turn Your Phone Off

This strategy works similar to airplane mode because it turns off all the components in your phone that would otherwise be using your battery. When your phone is powered off, it’s able to reach a full charge much faster. Keeping your phone on while it’s charging is like trying to sleep while you’re hungry or thirsty—it’s going to be much more difficult!

Use a High-Capacity Power Bank

Some power banks are more powerful than others. The heavy-duty ones are going to make your phone charge much faster than the smaller ones! However, not all phones can handle a high-powered portable charger. It’s best to contact the manufacturer of your cell phone to see what they recommend. Charging your battery with too much power is never a good idea!

Don’t Use a Wireless Charger

Wireless chargers are a genius invention, but they’re not the best option if your goal is to charge your phone quickly. Plugging your phone in directly to a power bank or outlet is the quickest way to bring it back to life because it’s directly connected to the power source!

At the end of the day, any way you can prevent your phone from using battery while charging will ultimately help it charge faster! You might also notice your phone charging slowly with a low-capacity power bank. Be sure that your phone and power bank are compatible for the most efficient charging.

How Long Do Power Banks Last? Top

The amount of time a power bank lasts varies from product to product, but on average, a power bank should last at least a couple hundred charging cycles.

If you use your power bank frequently, you’re going to consume more charging cycles than someone who only uses their power bank occasionally. There are more durable power banks out there than can last upwards of 1,000 charging cycles, but most of the smaller ones on the market have a lifespan of 200 or 300 cycles. The age of the power bank also has a significant impact on how long it lasts. As the batteries inside of the device age, they become less effective.

How to Store a Power Bank Top

Power banks should always be stored in a cool location that isn’t exposed to direct sunlight, such as a desk drawer. According to Battery University, batteries achieve optimum service life if used at 68 degrees Fahrenheit, or slightly below that temperature.

If you store your power bank in direct sunlight or a warm environment like the glove box in your car, it won’t last as long. It’s also best to store your power bank in a pouch or case when not in use. This helps protect the charging ports so they do not accumulate dust or debris!

Should You Buy a Power Bank? Top

If you’re always on the go or find yourself with a low battery, you should buy a power bank! They come in handy during vacations, trade shows, plane rides, or any time you are using your phone away from an outlet. The type of power bank you’ll need depends on your lifestyle and how many devices you need to charge.

There’s no reason to not invest in a power bank. They’re like an extra insurance policy for your phone’s battery! Having one with you just in case is always a good idea.

The Bottom Line

Power banks make our lives a bit easier by ensuring we never run out of juice. By using them properly, you’re not only protecting the power bank, but you’re also getting the most out of your investment! A properly cared-for power bank will get you through those long meetings and plane rides. Just think of all the adventures you’ll go on while still having peace of mind!

The best 20,000mAh power banks you can buy

A power bank is a great way to keep your devices charged while away from an outlet. You can get smaller portable batteries with 5,000mAh and 10,000mAh capacities, but those with 20,000mAh will last you longer and should charge your device several times. Here are our recommendations for some of the best 20,000mAh power banks you can currently get your hands on.

Best 20,000mAh power banks

Editor’s note: We will continually update this list as new 20,000mAh power banks are announced.

Anker PowerCore III

The Anker PowerCore III is a popular 20,000mAH power bank with a reasonable variety of ports: two USB and one USB-C. It can charge at speeds of up to 20W and is Qualcomm Quick Charge-enabled.

Anker is a super producer of charging devices, and this power bank is equipped with the Anker MultiProtect safety system. An 18-month manufacturer warranty adds extra peace of mind, and it’s available for 60 or less.

Anker PowerCore Essential

Anker has several 20,000mAh power banks, but one notable option is the PowerCore Essential. The battery features a USB-A port for output, along with a USB-C port for input and output. Thanks to support for Power Delivery, the USB-C port delivers up to an 18W output.

Anker’s pedigree and fast-charging capabilities are already good enough, but you can grab an 18W wall charger to juice the power bank to 100% in under seven hours. Also, keep in mind you can use it to charge other USB-C devices, such as tablets, smartphones, and even certain laptops.

Romoss 20,000mAh power bank

If you’re looking for a 20,000mAh power bank that doesn’t lack in the port selection, look no further than Romoss’s offering. The battery features three USB-C ports (two for output, one for input) and two USB-A ports (one for input, one for output). It’s a perfect companion if you’re hoping to charge your whole group’s devices on the go.

Crave’s Plus Pro portable charger is a three-port option equipped with Fast Charge IC 3.0. Two ports are USB-A, and the third option is a USB-C port with Power Delivery for up to 45W of charging. The power bank itself is only about the size of an average smartphone, so you should have no trouble stashing it in your backpack or even a

Once your Crave Plus Pro runs out of charge, use the USB-C input port to get back to full speed in a hurry. At just about 100, the Crave Plus Pro isn’t the cheapest option on the list, but three ports are a huge plus when charging.

Mophie Powerstation XL

At first glance, the Mophie Powerstation XL is a by-the-numbers portable battery. There are two regular USB ports and a USB-C port for input and output. The port selection isn’t varied, but at least the USB-C port can output at 15W.

Where the Powerstation XL differs from the competition is in material choice. The fabric material on the top and bottom is soft to the touch, even if you might need to clean it from time to time.

At around 60, the Powerstation XL is a bit more expensive than a few other options. However, it’s a straightforward 20,000mAh power bank that doesn’t try to be more than that. For some people, that’s enough.

Baseus 65W Power Bank

Baseus is a titan of the charging industry, and in the 65W charger, you’ve got a powerhouse on your hands. Equipped with one 65W PD USB-C port and two 30W QC USB-A ports, the power bank is a great option for juicing laptops and phones alike.

A numerical LED charge indicator gives you a more precise idea of how much more power can be squeezed from the device, and the 65W capability means that the power bank itself can be refilled in just two hours.

Omnicharge Omni 20 Plus

If you’re looking for a truly all-in-one portable battery, look no further than the Omnicharge Omni 20 Plus.

Finally, the small OLED display shows how much charge is left, how much wattage the Omni 20 Plus is outputting, and the estimated amount of time left until the battery dries up.

The Omni 20 Plus is also very heavy, even for a 20,000mAh portable battery. However, this is one of the most powerful options out there.

That’s it for our list of the best 20,000mAh power banks available. We’ll update this post with more options once they are released.
