High-Capacity USB Power Bank - Size Options

A power bank is judged by what it charges and how fast. This high-capacity model is listed in several capacities with a 120 W output class, for laptops and phones that accept fast charging.

✅ Carry reserve power for a laptop - The higher output class is intended for devices that draw more than a phone.

✅ Choose the capacity you need - Several capacity-labelled versions are listed, from smaller packs to large ones.

✅ Charge more than one device - USB outputs allow a phone and another device to be connected together.

Reserve power that covers a laptop

Capacity-labelled packs are heavier as they grow; a very large pack is a bag item, not a pocket one. Check that your device accepts the charging standard before expecting the fastest rate, because the pack and the device negotiate.

Air travel rules limit large lithium packs, so check the watt-hour figure against the airline before flying. Charge the pack on a non-flammable surface and do not leave it charging unattended overnight.
