Power banks and external batteries for charging phones, tablets, smartwatches and other portable devices away from a socket. Our range includes over 50 models, with products from BASEUS, BLOW, VENTION and TRUST among others. You will find portable power banks and also a few batteries whose capacity is listed in watt-hours.
How to choose a power bank
Capacity. Our range includes models of 5000, 10000 and 20000 mAh. 5000 mAh usually charges a phone about once, 10000 mAh gets you through a few days without a socket, and 20000 mAh is worth choosing if you charge a tablet or several devices. The energy you actually get is always lower than the rated figure, because some is lost when the voltage is converted.
Ports and number of devices. Some models have one USB Type-C port and others have two, and the range allows charging from one to three devices at once. If you travel with another person, or carry a phone and a watch, choose at least two outputs. USB Type-C is also handy because the power bank itself can often be recharged with the same cable as your phone.
Charging power. A phone needs modest power, but a laptop needs a battery that delivers enough watts and has enough watt-hour capacity. Before buying, compare the power bank's output with your laptop charger's rating.
Display. Some models have a built-in display that shows the remaining charge. It helps when you need to know whether there is enough for the trip, rather than guessing from a few indicator lights.
Compatibility with your device. If you are looking for a device battery rather than a portable power bank, check the model compatibility, the voltage (our range includes 3.6, 3.7 and 3.85 V) and the capacity in Wh. A battery with the wrong model or voltage may damage the device or simply not work.

Frequently asked questions
What power bank capacity do I need for a phone?
For most phones, a 5000 or 10000 mAh power bank is enough. The first usually charges a phone about once, the second twice or more, depending on the phone's battery size. If you also charge a watch or earbuds, choose 10000 mAh or more.
What is the difference between mAh and Wh?
mAh shows charge, while Wh shows actual energy, so Wh is better for comparing batteries with different voltages. As a rough guide, multiply mAh by the voltage and divide by 1000 to get Wh. Wh matters more for laptops and for airline rules.
Can I take a power bank on a plane?
Yes, but it must go in your hand luggage, not in checked baggage. Most airlines allow batteries up to 100 Wh without special permission, so check the capacity and your airline's rules before flying.
Can I charge a smartwatch with a power bank?
Yes, if the watch charger connects via USB and the power bank has a USB output. Some power banks switch off when a connected device draws very little current, and smartwatches often do exactly that. Look for a model that lists a low-current mode.
