- What's the output efficiency of Upgraded PowerCore Speed 20000?
- Upgraded PowerCore Speed 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.
- Can Upgraded PowerCore Speed 20000 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 portable chargers.
- My device charges at 1 Amp, will PowerCore Speed 20000's higher output harm it?
- No, it will only supply the maximum output current necessary to charge your device.
- Can Upgraded PowerCore Speed 20000 charge two devices simultaneously?
- Yes. Only the QC port can fast charge Qualcomm Quick Charge devices.
- What do the LEDs indicate when Upgraded PowerCore Speed 20000 is charging itself or other devices?
- "When Upgraded PowerCore Speed 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 Upgraded PowerCore Speed 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."
- How long will the charge in Upgraded PowerCore Speed 20000 last without being used?
- Generally, our 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.
- Can Upgraded PowerCore Speed 20000 be used for international travel?
- Yes, it 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.
- Can Upgraded PowerCore Speed 20000 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. 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.
