PORTABLE CHARGING 101. Anko portable charger

How to charge anywhere.

Mobile devices like smartphones and tablets make life so much easier. That is, until they run out of battery power when there’s nowhere to plug in.

The answer is a portable charger.

A lightweight power bank or mobile battery pack that you can carry anywhere.

They go under different names: battery packs, power banks, portable chargers, fuel banks, power cells and back-up charging devices to name just a few.

But whatever you call them, they all do the same thing.

Charge your phone or tablet without needing a power outlet.

Simply charge it up at home, throw it in your bag or your. and connect it to your phone whenever it needs a quick battery boost.

You’ll never suffer from “low battery anxiety” again.

Charge anywhere.

Make sure you’re always connected with back up battery power that’s as mobile as you are.

Battery packs come in all shapes and sizes, smaller sizes for an essential smartphone boost in your. or bigger sizes for multiple charges or to charge a tablet.

Choose one with cables included, or one with multiple ports to charge more than one device at a time.

Pick out a power fortress or something small and sleek, and take the power to charge anywhere, with you everywhere.

Start by choosing the size of your battery (aka power bank).

This is not just about which one will fit in your or your purse. The size of the battery is about the power inside. Most batteries will feature a number on the front that tells you the number of mAh or “milliamp-hours.”

Common sizes range from 2000mAh up to 10,000 or even 12,000 mAh. Bigger numbers mean more power, which means more recharges for your smartphone, or charging for bigger devices that need more power, like a tablet.

Charges an iPhone 7 (running iOS 10) up to 1.5 times on a single charge in internal testing.

Charges an iPhone 7 (running iOS 10) up to 3 times on a single charge in internal testing.

Charges an iPhone 7 (running iOS 10) up to 5 times on a single charge in internal testing

We’ve used smartphones and tablets to compare battery sizes, but most battery packs will charge any device that charges via USB, such as a GoPro camera, Kindle reader or Bluetooth headset. Bigger devices that draw more power will need bigger batteries. more mAh. to charge them fully.

How to ensure fast charging for your phone/tablet.

Technically the standard USB port on your battery pack (aka power bank) will fit any standard USB cable. However, the amount of power it can provide may vary.

= Minimal Speed

= Better Speed

= Fastest Speed

1 AMP/ 5WATT A 1 amp USB port will charge your smartphone or tablet but may charge slowly, even if the battery is big enough to charge your smartphone more than once.
2.4 AMP / 12WATT This will charge most smartphones at the fastest possible speed for smartphones. This is also called “optimal charging.”

“Shared” is the combined power available on multi-port power banks, and is different from “total power”. Learn more

How many devices do you need to charge?

Bigger batteries (aka power banks) – with more mAh – sometimes have more than one USB port, because with all at that power inside, why not share it out?

This can be useful to charge two smartphones at the same time – maybe to give a battery boost to a friend.

Or you can charge your smartphone and your GoPro at the same time.

Or your smartphone and your Bluetooth headset.

Or even a smartphone and a tablet, if you choose a battery with enough mAh to provide all that power.

With multiple ports, simultaneous charging is super-easy.



The quality of your cable can help to determine how quickly your power bank (aka portable charger) and attached devices power up. Higher quality cables also protect your devices from overheating and harmful power surges.


Every power bank (aka portable charger) needs to be charged. This usually requires a standard USB to Micro-USB cable. Simply connect your power bank input port (usually Micro-USB) to a standard USB wall charger.


Most power banks (aka portable chargers) charge via a USB port, simply connect your device to the USB port and begin charging. Some power banks come with a cable, or a variety of cables, that are detachable. This makes it easy to switch between cables for your iPad, your Samsung phone, or other device. Other power banks have a cable hard-wired to the pack. This prevents losing the cable, but makes the power bank less versatile overall.

Explore Battery Packs

There is no such thing as a magic battery pack.

Unfortunately, no battery pack has been invented that magically recharges itself when it’s empty. But on the whole, they are pretty simple to charge.

If you need one immediately, check on the package if it’s ready to use when you buy it. Some will need to be charged at home before they can be used.

To charge, plug the supplied cable into the input port on the battery pack. Attach the other end, usually a standard USB, into a wall charger or other power source.

Battery pack input ranges from 1Amp up to 2.4Amps. Put simply, the bigger the input number, the faster it will recharge. Most wall chargers deliver up to 2.4Amps, but it’s worth checking the charger if you’re in a hurry, as a 1Amp charger might take twice as long.

Some battery packs have an LED indicator, which tells you how much power the battery pack has left. This will tell you when you need to recharge the battery.

A power bank (aka portable charger) seems like a good idea. But is it safe?

Some power banks are carefully designed and rigorously tested to offer complete peace of mind, that is backed up by robust warranties and guarantees. Some warranties protect the power bank itself, while others also safeguard the electronic devices you attach to it, like your phone, tablet or smartwatch.

Some batteries might not offer such peace of mind. Opting for low cost or counterfeit products can turn out to be expensive, even dangerous. It’s easy to avoid this by following these simple steps.


Some power banks (aka portable chargers) require you to register your purchase, by providing the serial number either online or via a helpline. This is a good way to activate your returns policy and ensure your product is not a counterfeit.

Manufacturer, country of origin and the type of power bank may mean differences in the types of warranties and what they will cover



Covers the power bank (aka portable charger) for a specific period from the date of purchase, and usually requires you to keep your receipt to prove purchase date.


Covers the power bank (aka portable charger) for the reasonable life expectancy of the product, which may vary according to manufacturer.


A more robust warranty which not only covers the power bank (aka portable charger) itself, but will also offer to repair or replace devices that are damaged while “properly connected” to the power bank, in line with manufacturer guidelines. Such warranties usually have a clause stating up, “up to 1,000” or similar. The amount should be enough to cover the types of device recommended for use with the power bank, such as a smartphone or tablet.

A robust quality assurance offers durability and peace of mind.

Rigorous testing and thorough investigation of product performance make your battery pack more likely to last longer, and less likely to harm you and your valuable electronics.

Safe battery packs should have undergone the following testing


efficient battery packs will have a lower operating temperature, which wastes less energy, giving it longer life expectancy.

Over Current Protection

OCP prevents too much power going into the battery pack and the power going out to the connected equipment, protecting the delicate circuitry of both devices.


Like OCP, OVP protects both the battery pack and the connected device by keeping the voltage within recommended safety parameters to avoid damage.

Over Discharge/Charge Protection

High-performing batteries should not be overcharged or fully discharged to prolong their life expectancy. Some battery packs consistently monitor charge states to prevent this from happening.

Heat Tests at Extreme Temperatures

While using batteries in extreme temperatures isn’t advised anywhere, it can be a good indicator of weaknesses in design and construction. Batteries which pass such stringent testing will be more durable and offer improved assurances of overall safety and performance.

Compliance with legal standards of safety.

These logos or marks, usually found on the packaging, will indicate that they have passed the necessary industry standard regulations, to comply with and achieve the following certifications.

To learn more, please see CHARGE ANYWHERE above, or The Cheat Sheet below.

While many battery packs may look identical, when it comes to safety, it’s what’s inside that counts.

mAh mAh stands for Milliamp Hours and quantifies the energy storage capacity. It is based on how long a battery will last when power is drawn constantly, e.g. a 2000 mAh battery will power a device drawing 100 mAh for 20 hours.

Amps Short for ampere, this is a unit of current, not a unit of charge. It describes the constant and average current that passes through the circuit.

Shared vs. Total Shared power banks will provide power where it’s needed, e.g. a 2 x 1.7A [3.4A shared] will charge two smartphones at 1.2A each, or one tablet at 2.4A. Some multi-port power banks (aka portable chargers) will have fixed outputs on each port, e.g. a 2 x 1.2A [2.4A total] and will charge two smartphones at 1.2A. This is what is referred to as, “total” power.

Smartphone A mobile phone with an advanced mobile operating system, usually with internet access, touchscreen interfaces, cameras, media players and the ability to run third-party apps.

Tablet A mobile computer with a touchscreen display, circuitry and battery in a single, portable device, usually featuring pop-up, virtual keyboards for typing.

USB port Short for Universal Serial Bus port, a USB port is designed for use with an industry standard connector to communicate data and supply electric power between devices.

Standard USB—Also known as USB-A The most common, universal connector on the “other end” of most current USB cables, is a USB-A. These are often suitable for use with computers, car chargers, wall chargers, and many other devices.

Micro-USB Micro USB is a USB connector that is smaller than USB-A, and is often found on smaller or thinner mobile devices, such as Android smartphones, digital cameras, battery pack input ports, Kindle readers and many others.

USB-C—Also known as Type-C USB-C is a new type of USB connector, hailed as the new standard. Smaller, faster and more user-friendly than previous USB types, USB-C has widespread support from industry leaders, meaning that USB-C will come to replace all other USB types.

Lightning A connector developed by Apple to replace the 30-pin connector. Used across all iPhone, iPod and iPad releases since iPhone 5, iPod Touch (5th generation) and iPad 4th generation.

Optimal Charging The fastest possible charging for the connected device is optimal charging. Larger devices require more power, so a charger with limited output may still power up, but will take longer to fully charge

What to Do When Bluetooth Headphones Won’t Charge [Ultimate Guide]

Check out these top tips and fixes to get your Bluetooth headphones charging again in no time.

The portability of Bluetooth headphones has made listening to music and podcasts much easier all-day, even while on the go.

However, problems with charging and batteries, usually from damaged cables and charging ports, can render wireless headphones useless. Ultimately, this can put a damper on your listening experience.

Luckily, fixing your Bluetooth headphones can be as easy as removing debris from the charging port, or replacing your battery or charging cable. Keep reading to learn the common fixes to headphones that won’t charge, plus other solutions based on your headphones’ brand.

Bluetooth Headphones Won’t Charge: 7 General Solutions

When Bluetooth headphones won’t charge, it’s mostly due to problems with the port, charging cable, or batteries. So, regardless of brand, there are universal solutions you can try to get your Bluetooth headphones charging again.

Here are some general fixes for Bluetooth headphones that won’t charge:

Charge directly via a power outlet and not a USB hub

Make sure to try plugging your headphone charger directly into a power outlet, instead of USB hubs.

USB hubs, while useful, can often be insufficient for charging your headphones. This can be the result of a faulty USB hub or because the USB hub can’t provide enough power to charge the headphones.

Although USB hubs meet the minimum voltage required to charge headphones, which is around 5V, the problem lies in the electric current they supply. Most USB hubs can only output 0.5A or 2.5W at a time, which corresponds to only 1/2 to 1/3 of the output of charging bricks directly connected to a power outlet.

See if there is any debris in the port

Debris in the charging port can hinder your device from receiving power properly from your charger. In most cases, cleaning the port is enough to get your headphones charging again.

This method is super easy and can be done in no time. All you’ll need is a can of compressed air and a toothpick or any thin, non-metallic object.

Here’s how you can clean your headphones’ charging port:

    Start by firing compressed air into the port to drive out debris.

When spraying your can of compressed air, make sure to hold the can upright to avoid spraying water into the port.

Check the port to ensure all debris has been cleared. If there is any dirt remaining, carefully use a toothpick or a thin, nonmetallic object to remove it. Gently scrape the port from wall to wall, while avoiding the pins inside.

Be careful when cleaning the interior of the charging port, as the electrical connectors inside are delicate and can be broken if too much force is applied.

  • Once you’re done clearing away debris, blast compressed air into the port a few more times to ensure all residue is cleared out.
  • Try a different charging cable

    Charging cables house delicate wires that can break with too much tension. That said, it’s hard to tell if a cable is broken, as the damage is internal most of the time. To rule out whether the charging cable is the problem, try charging the headphones with a different cable.

    If there is visual damage to the cable, like exposed wires, you can try repairing the cable yourself. These solutions are super easy, and they can save you a few bucks.

    Check if the charging port is loose or damaged

    Much like the case of a loose headphone jack, a loose charging port can also result in many frustrating issues.

    Inspect the charging port of your headphones for any damage like bent connectors or bent metal. Also, make sure that the port itself isn’t loose when you touch it, as this could be a sign that the connectors have detached from the headset.

    Keep the headphones connected to the charger for a few hours

    Your headphones’ batteries can become over-discharged if they haven’t been used for a while. This means they will need to be plugged in for longer before the battery can begin to charge again.

    Make sure they’re properly seated on the charging stand or case

    Some headphones aren’t charged directly through a cable but instead through a stand or case that has a cable connected to it. If this is the case for you, make sure your headphones are positioned properly so that they can accept a proper charge.

    Do a hard reset

    Doing a hard reset can solve many problems, including headphones that aren’t charging. The actual process for performing a hard reset can vary from model to model, but you can check out our full guide on how to reset your headphones to get it done without much fuss.

    How to Fix Bluetooth Headphones Charging Issues According to Brand

    As each pair of headphones is different based on the brand, solutions for each brand will also differ. If you didn’t have any luck with the previous solutions, let’s move on to more targeted solutions depending on your headphone brand.

    Before continuing, check if your headphones are still under warranty. If they are, it’s best to use your warranty first to repair or replace your headphones. Some solutions outlined below are invasive and may void your warranty, so we recommend utilizing your warranty if it’s available.

    For Airpods

    There’s no other way to charge Airpods, except via the charging case. So, if there is debris blocking the Airpods from making contact with the charging pins inside the case, they won’t charge. There are also cases when only one AirPod would charge, but the other one won’t.

    To remedy this, you must clean your Airpods and charging case regularly. Here’s how:

    • Start by soaking the tips of a cotton swab in alcohol. Use this to gently clear away any debris from the charging pins found at the bottom of the case.
    • Consider using a toothpick to remove dirt from spots inside the case that are harder to reach.

  • Finally, use a microfiber cloth to clean the Airpods themselves, focusing on the tail.
  • You can also use a soft-bristled toothbrush to clean the case’s charging port to ensure the case itself can be charged. If your Airpods still don’t charge after trying all these steps, consider performing a factory reset of the Airpods.

    For Beats

    Beats headphones use lithium-ion batteries. These batteries are popular for their high energy density, which means that, although they’re small, they can hold a large amount of charge.

    However, lithium-ion batteries have a limited number of times they can be charged. Over the years, as they get charged, their battery capacity decreases.

    This means that older headphones are more susceptible to a burned-out battery, which results in the headphones either not holding a charge or not charging at all.

    To fix this, you can replace the battery inside your Beats headphones. To do so, follow these steps:

      Remove the casing outside of the speaker to expose the battery.

    For Bose

    If your Bose headphones are having some difficulty charging, there are different solutions you can try to resolve the issue.

    These solutions must be followed in order. Make sure to only try the last one if the first two have not worked for you.

    To begin, try the following steps:

    • Before charging, turn your headphones off by holding the power button for around 30 seconds.
    • Charge your headphones using the USB charging cable.
    • After 5 seconds, unplug the charger. Then, wait for 1 minute before turning the headphones back on.
    • Plug the headphones back in and see if they start to charge.

    If the above steps didn’t work for you, try updating the firmware of the headphones:

    • Download the Bose Software Updater to your PC.
    • Plug your headphones into the PC and follow the prompts given by the Bose Software Updater.

    If neither of the above solutions fixed your problem, it’s time to take a more hands-on approach and replace the charging port on the headphones. This solution will require some technical skills, and may require the assistance of a professional in order to be performed correctly.

    For Jabra

    Here’s what you need to do:

    • Put the earbuds in the case and plug the case in to charge completely. This can take up to two and a half hours for them to charge completely.
    • Once the case is completely charged, remove the earbuds and then insert them back into the case. Make sure that each earbud flashes red when inserted.
    • With the lid open, plug the case into a power source.
    • After the battery level LED light shows after 3 to 5 seconds, close the lid and allow the earbuds and the case to charge for another to 2 hours.

    For Logitech

    Logitech charging issues are commonly caused by a faulty micro-USB connector. Over time, the action of plugging in the charging cable and removing it will gradually weaken the 5-pins inside the charging port.

    Fixing this problem at home can be challenging as it requires the speaker piece to be removed and dismantled. Because of this, we recommend that you seek out the services of a professional to avoid further damage. But, if you are confident in fixing the problem yourself, simply follow these steps:

    • Remove the left ear pad to expose the left ear cup.
    • Remove each screw, then carefully pry the headphones open.
    • Carefully put the microphone to the side to avoid damaging it. Then, look closely at the charging port to identify the issue. Use a microscope if available.
    • If the pins in the charging port are moving, solder them back into the board to keep them in place.
    • Return the mic and the left ear cup back to their original position, then secure them with the screws. Put back the ear pad and check if the headphones are charging.

    For in-depth instructions and a visual guide to these steps, take a look at this video on repairing your Logitech headphones’ charging port.

    For Sennheiser

    Sennheiser headphones can occasionally experience a glitch where the LED indicator light may flash or remain on, even after charging. This issue usually subsides over time with multiple charging cycles, so it’s recommended to use your headphones regularly until the light synchronizes with the battery.

    If the headphones don’t work and will not accept a charge, you can try changing the battery inside the headphones. However, be warned that this is a technical process. If you’d like to give it a try, here’s what you need to do:

    • The headphones’ battery is found in the left ear cup. Open this by removing the ear pad and the four screws on the cup.
    • Carefully remove the top part of the ear cup, making sure that you don’t pull the attached wires.
    • Using a tweezer, gently disconnect the battery clips from the board.
    • Then, with a flat, sturdy object, carefully lift the battery out of its position. Completely remove the battery and the disconnected wire.
    • Put in the new battery exactly where the old battery was, then clip the battery wires onto the board.
    • Close the ear cup and secure it into place with the screws. Then, place the ear pad back before checking if the headphones are now charging.
