Unbeatable Charging Speed
PowerCore Speed 20000 QC combines 3 distinct fast-charging technologies to ensure that any and all devices are charged in the shortest time possible. Never worry again about having no time to charge.
Power for Days
Over a week's worth of power that goes anywhere you do. Charges an iPhone 6s over 7 times, a Galaxy S6 5 times and most tablets multiple times.
Cool Under Pressure
PowerCore Speed uses exclusive technology developed by Anker engineers to control its temperature when charging. If high temperatures are detected then it automatically modifies power output to reduce heat.
Surge protection, short circuit prevention, temperature control, and other advanced safety features keep you and your devices safe.

Approximately 30% to 40% of the battery capacity is unable to be used because of efficiency complications that affects all electronic devices. These include power lost from circuit heat and voltage conversions from the battery, the charging cable and your device
- Can PowerCore Speed 20000 QC charge other devices while it is being charged?
- No, we have disabled this feature due to the detrimental effects it has on the lifespan of external batteries.
- My device charges at 1 Amp, will PowerCore Speed 20000 QC's higher output harm it?

- Can PowerCore Speed 20000 QC be taken on board airplanes?
Yes, all external batteries with a capacity lower than 27027mAh (100 Watt Hours) can legally and safely be taken on board airplanes according to Federal transportation security rules:
In March 2017, the governments of the United States and the United Kindom issued orders restricting a variety of different electronics from carry-on baggage when traveling to the USA and UK. The ban is likely to result in difficulties carrying portable chargers from major airports in Africa and the Middle East (with more airports expecting restrictions soon). Therefore, we strongly recommend that you confirm with your airline or airport before traveling with portable chargers to ensure problem-free flying.
