Two-pack 10000mAh power banks for iPhone users
This twin pack supplies two 10000mAh lithium-ion units built for iPhone owners who want a lightweight backup. Each bank weighs .51 lb and measures 5.47 in by 2.71 in by .7 in, so both slip into a pocket or bag. The LED screen shows exact charge from 1% to 100%, removing guesswork before travel.
Plug in and charge; cables
No software or driver setup is required — just connect a compatible cable to the USB-C or USB-A port. The pack does not ship with a charging cable or mains adapter, so buyers must provide their own. Ensure the cable supports the stated output to reach the advertised speed.
22.5W USB-C output decides charging speed
The USB-C port delivers up to 22.5W while the USB-A port supplies 5V/3A, allowing two devices to charge together. If your device cannot accept 22.5W over USB-C, the faster rate will not be used. Check your handset’s supported input before relying on the 30-minute 55% claim.
