Accepted Answer

Yes, PowerCore II 20000 can charge the new iPhone 8 and iPhone 8 Plus faster than the OEM wall charger , but an Apple charging cable is not included. Use your device's original (OEM) cable or purchase a third-party certified (MFI) cable separately.

Question 5

What's the output efficiency of PowerCore II 20000?

Accepted Answer

PowerCore II 20000's output efficiency is 60%-70%. Approximately 30% to 40% of the battery capacity is unable to be used because of efficiency complications that affect all electronic devices. These include power lost from circuit heat and voltage conversions from the battery, the charging cable and your device.

Question 6

Can PowerCore II 20000 charge other devices while it is being charged?

Accepted Answer

No, we have disabled this feature due to the detrimental effects it has on the lifespan of portable chargers.

Question 7

My device charges at 1 Amp, will PowerCore II 20000's higher output harm it?

Accepted Answer

No, the PowerCore II 20000 will only supply the maximum output current necessary to charge your device.

Question 8

Can PowerCore II 20000 charge two devices simultaneously?

Accepted Answer

Yes.

Question 9

How long will the charge in PowerCore II 20000 last without being used?

Accepted Answer

Generally, our external batteries' static power consumption is so low it would take between 20 and 36 months to drain completely. However, it is also worth noting that their chemicals will become less active if left unused for extended periods. To extend battery lifespan, discharge and recharge it at least once every 4 months.

Question 10

Can PowerCore II 20000 be used for international travel?

Accepted Answer

Yes, PowerCore II 20000 can be used internationally. Just be sure that your USB wall charger is compatible with the voltage of the country you're travelling to. The input voltage of an adapter is usually labeled on the adapter itself.

Question 11

Can PowerCore II 20000 be taken on board airplanes?

Accepted Answer

Yes, all external batteries with a capacity lower than 27027mAh (100 watt hours) can legally and safely be taken on board airplanes. 

To calculate an external battery's capacity in watt hours: (Battery mAh Capacity X 3.7)/1000. 

Here are the relevant requirements quoted from federal transportation security rules:

Effective January 1, 2008: Passengers may carry consumer-sized lithium ion batteries (a.k.a. rechargeable lithium, lithium polymer, LIPO, secondary lithium) with no more than 8 grams of equivalent lithium content or 100 watt hours (wh) per battery. This size covers AA, AAA, 9-volt, cell phone, PDA, camera, camcorder, Gameboy, and standard laptop computer batteries. Passengers can also bring two (2) larger lithium ion batteries (more than 8 grams, up to 25 grams of equivalent lithium content per battery) in their carry-on. This size covers larger extended-life laptop batteries. Most consumer lithium ion batteries are below this size.

Question 12

What should I do if PowerCore II 20000 doesn't recharge?

Accepted Answer

Please try a different AC adapter and Micro USB cable to see if that helps. Email us at support@anker.com during your 18-month warranty period if this doesn't fix the issue.

Question 13

What should I do if PowerCore II 20000 doesn't charge other devices?

Accepted Answer

Please try using a different charging cable between PowerCore II 20000 and your device. Email us at support@anker.com during your 18-month warranty period if this doesn't fix the issue.

Question 14

What do the LEDs indicate when powercore II 20000 is charging itself or other devices?

Accepted Answer

\"When PowerCore II 20000 is charging your device, the LED power meter will stay on, displaying the battery’s remaining power. The light will fade when the device is fully charged and no longer drawing a current. The last LED light will flash when the remaing power is lower than 10% and turn off when lower than 5%.

When PowerCore II 20000 is being charged, the LEDs will flash and light up one by one to show the progress of the recharge. They will turn off when the PowerCore is fully charged.
