help Belkin BoostCharge 20K FAQ
How many times can the Belkin BoostCharge 20K charge my smartphone?
With 20,000mAh you can recharge a typical 3,0004,000mAh smartphone roughly 45 times before the bank runs out. Actual cycles vary based on the phones battery health, screen size, and usage during charging.
Does it support fast charging for iPhone and Android devices?
The BoostCharge 20K outputs via USBA at 5V/2.4A, which is the standard rate, not the highervoltage fastcharge profiles used by iPhones Lightning or many Android phones. Those devices will still charge, but at a slower pace than a PDenabled charger.
Can I charge two devices at the same time, and will it affect charging speed?
Yes, the two USBA ports can be used simultaneously. Each port can deliver up to 2.4A, but the total combined output is capped at 3.4A, so if both devices draw power they may charge a bit slower than when alone.

The 20,000mAh (74Wh) rating stays under the 100Wh limit most airlines allow for portable batteries, so you can normally bring it in your carryon bag. Always confirm with your carrier, as some restrict multiple large power banks.
