Before you buy a power bank there certain things that you must consider. These things determine what power bank will be best for you. These factors are: Capacity The best power banks we have tried have all come from Anker, but that doesn't mean Anker is the only brand you should consider. All of the power banks on this list passed our testing, traveling with us on the road and powering our devices at home. Anker is the best, but these batteries from Baseus and Otterbox performed well. The Anker Prime series of Power Banks, including the Anker Prime 27,650mAh Power Bank (250W) and the Anker Prime 20,000mAh Power Bank (200W), are for people who truly love to geek out on power banks. If you came looking for the absolute best power bank you can buy, this is the best we've tried. The power bank is designed to remain working for 6 seconds after being disconnected from a mobile device. To use a Huawei power bank, connect one end of the data cable to the USB Type-A port of the power bank and the other end to the device you want to charge. Double-press the power button to activate low-current charging mode for devices like headsets, watches, or bands. 2. Can I use any charger for Huawei?The next question is how you want to charge your device. You can find a power bank that charges your phone (or even your Apple Watch) wirelessly. These will usually charge slower, but they can be very convenient if you want to leave wires at home. Connect one end of the data cable to the USB Type-A port of the power bank and the other end to the device with a low charging current (such as a headset, watch, or band). Double-press the Power button. When the indicator flashes alternately, the device will enter the low-current charging mode for 2 hours. Press the Power button again to exit the low-current charging mode. It's also worth considering how many devices you need to charge at once. If you often travel with multiple devices, you may want to opt for a power bank with multiple outputs, so you can charge them all at once. Portability You don't need all those extras: The Anker Prime power bank is pricey, and if you don't care about monitoring charge Wattage or days of battery life, find another option.

When considering portability, think about the size and weight of the power bank. A smaller, lighter power bank may be more convenient for everyday use, while a larger, heavier power bank may be better suited for longer trips.

Power Input-output is measured in Watt and it is a very important factor when it concerns charging time. Usually, a power bank with a higher Wattage Input-output capacity can charge a smartphone faster. PortThere are plenty of combination power bank and some other device, but the Tylt Bottle 2 actually makes sense because we're usually carrying an insulated water bottle anyway, so we might as well screw a battery onto the bottom. With a 5,700mAh capacity, the Tylt Bottle 2 is just enough to get us through a very busy day, or keep the phone powered while we play games at the cafe. There are plenty of other power bank makers around, and most of them have not caught up to the faster charging speeds available on the iPhone 15 family, let along even faster Android phones. Except for unique form factors or serious bargains, we stayed away from recommending power banks from reputable makers if they couldn't charge at 2023 speeds. Capacity:Think of capacity as the energy reservoir of your power bank. The higher the mAh (milliampere-hour), the more power it can store. So, choose a power bank with a capacity that suits your charging needs and can juice up multiple devices.

A battery maker will claim between 60% and 70% efficiency, so that 10,000mAh battery will only give your phone around 6,000mAh of extra battery charge, at the least. In practice we find around 65% efficiency, though occasionally we can do even better.

If you remove the charging cable after the power bank is fully charged, the voltage of the power bank will drop slightly due to the characteristics of the lithium-ion battery in the power bank. If you insert the cable again, the system will consider that the power bank is not fully charged. If the voltage and current reach the preset value after a short period of time, the system will consider that the power bank is fully charged and all four indicators will turn on. Tylt also wisely left enough of a gap between the battery and the bottle that you can coil a small USB-C cord (included) into that space. That way, even if you're not charging wirelessly, you're not adding a lot of extra bulk to your bag. It's a smart setup. It's also important to choose a brand that offers a warranty, so you can have peace of mind knowing that your power bank is covered in case of any defects or issues. Conclusion The power bank can only stop the power output when the current is below the preset value for more than 90 seconds. Some phone models are still in the final charging state when the battery level has reached 100%, and the current may be greater than the preset value. When using the power bank to charge a phone that supports 9 V/2 A fast charging, the phone screen is on and indicates that the phone is in fast charging mode, but the indicators of the power bank do not indicate fast charging. The charging system of the phone may have limited the charging speed to control the amount of heat that is generated. In this case, the power bank will automatically resume fast charging and its indicators will turn green again after the phone screen turns off.The Anker Nano is only 5,000mAh, but that doesn't mean it can fully charge a 5,000mAh phone battery like you'll find in the Galaxy S23 Ultra. Power banks are about 60-70% efficient, depending on the phone's technology, so this power bank is good for charging an iPhone 15 to nearly full, but that big Ultra will only get about 65% charge. You don't have a magnetic phone: You don't need an iPhone to enjoy the magnetic charging, but you'll need a case that lines up your phone with Apple's MagSafe wireless configuration, or else your phone won't charge properly. Charge it Fully: Plug in your power bank and let it charge fully before using it. This ensures that it's ready to provide a reliable power source when you need it.
