A campsite at dusk with a dead phone is the moment that answers what is a portable charger in practical terms. A portable charger is a rechargeable battery pack that charges a phone, tablet or watch away from a wall outlet, and it recharges itself from a USB cable or a built-in wall plug. The 4 listings in this guide are power banks with built-in cables, wall plugs, outputs and displays, and they differ in how many devices they charge at once. This guide explains what each figure means and lines up the 4 chargers so you can match one to the devices you carry.

What is a portable charger?
A portable charger is a battery with charging outputs in a pocket-size case. You charge the pack itself first, then it charges your devices from its stored energy, with no outlet needed while it works. The pack lists its capacity in mAh, its outputs in watts or amps, and its cables and ports on the listing. When the pack runs low, you recharge it from a wall outlet, a USB port or its own built-in plug.
What the numbers on a portable charger mean
Capacity in mAh sets how much charge the pack holds: the 10000mAh listings here hold more than the 5000mAh RORRY pack. Output in watts sets how fast a device charges: the citicr listing states PD20W and SCP22.5W, and the charmast listing states 3A charging. Outputs set how many devices charge at once: the charmast listing states 6 devices at once, the citicr listing states 5, and the VEGER listing states 4. Match the capacity to the devices you carry and the outputs to how many charge at the same time.
| Charger | Capacity | Devices at once | Built-in cables | Amazon |
|---|---|---|---|---|
| charmast | 10000mAh | 6 | 4 built-in cables | |
| citicr | 10000mAh | 5 | iOS and USB-C cables | |
| VEGER | 10000mAh | 4 | iOS and USB-C/Micro USB cables | |
| RORRY | 5000mAh | Watch, phone and earbuds | Built-in cables |
Built-in cables, wall plugs and displays
Built-in cables remove the need to carry cords: the charmast listing states 4 built-in cables, the VEGER listing states 2 cables, the citicr listing states 2 built-in cables, and the RORRY listing states built-in cables without a count. A built-in wall plug removes the need for a separate adapter: the citicr and VEGER listings state a fold-out or built-in AC plug. An LED display shows the remaining charge: the charmast, citicr and VEGER listings state an LED display, while the RORRY listing states no LED display.
