Ready-to-go power bank for daily carry

The CFIAI PB-08 packs a 15000mAh lithium-polymer cell into a 5.9 x 2.69 x 0.6 in frame. A built-in USB-C cable and an iOS cable handle the two most common phone ports so nothing extra is needed. Travellers who want one device that tops up a phone and a tablet without loose wires will find it fits the brief.

Plug straight into devices, no extra leads

The integrated cables feed power directly to a phone or tablet while two additional ports — USB-A and Micro-USB — stay free for a second gadget or a friend’s device. Because the cables live inside the shell, nothing tangles in a bag and nothing gets left behind at a café. Users who need to charge three items at once or who prefer a dedicated laptop charger will need a larger unit.

Runs cool and quiet on every trip

The 3.7 V pack delivers up to 22.5 W through the built-in USB-C link and drops to a trickle mode for earbuds or watches. No fan means silent operation and the slim profile stays comfortable in a pocket during long walks. The 55.5 Wh rating keeps it within carry-on limits for air travel. Builders who want pass-through charging or a higher single-port ceiling should look elsewhere.

Questions about this item

How many full phone charges can the 15000mAh capacity deliver before the power bank itself needs recharging?

The 15000mAh battery stores 55.5Wh at 3.7V, typically providing several full smartphone charges depending on the device's own battery size.

Does the 22.5W fast charging cause the unit to become hot or noisy during extended use?

The slim 5.9×2.69×0.6 in lithium-polymer design has no moving parts, so it runs silently and stays cool under normal 22.5W loads.

Which charging cables must I already own to use every port on this power bank?

Built-in USB-C and iOS cables cover most devices; only Micro-USB or extra USB-A cables are needed for legacy gear.
