A:AnswerThe power bank can charge the switch, but if you want a good charging experience,you need to consider the power bank's efficiency, and the condition of the Switch's battery.
A:AnswerThe Anker Power Bank (20000mAh, 20W, 1-Port) can charge an Apple Watch Model A2291, but you will need to use the Apple Watch's proprietary charging cable.
A:Answerwe charged 2 phones at same time. Not sure about the voltage conversion as i have tower with several usb and electrical plug in that converts the voltage to 110v.
A:AnswerYes, an Anker power bank can be used to power a heated jacket, provided the jacket is designed to be compatible with USB power banks. Most heated jackets that are compatible with power banks require a USB connection and can draw power from a standard USB port, which is a common feature on Anker power banks.
A:AnswerThere is 4 green dots around the power button. When the the device is charging, they will show the level of charge. When all 4 lights are solid green, the device is fully charge. I recommend using a high-speed phone charger because it will take a while on just 5 volts.
A:AnswerTo get a rough estimate, you can use the following formula:
(Number of recharges) = (Power bank capacity in mAh) * (Efficiency) / (Phone battery capacity in mAh)
For example, if you have a phone with a 3000mAh battery and we assume an efficiency of 80%, the calculation would be:
(Number of recharges) = (20000mAh) * (0.8) / (3000mAh)
(Number of recharges) = 16000mAh / 3000mAh
(Number of recharges) ≈ 5.33
