Can it charge low-current devices like earphones?

Yes, this power bank features a low-current charging mode.Simply double tap the power button to enter this mode to charge small electronic devices and double tap again to exit!

Does it support charging while discharging?

Yes, the power bank supports pass-through charging, allowing it to be recharged while it charges devices like smartphones simultaneously.

Can I bring it on a plane?

Yes, in general, power banks with a battery capacity under 27,027 mAh (100 watt-hours) can be legally and safely carried on planes.

How can I estimate the number of charges for my device?

To estimate charges, use this formula: (Power Bank Capacity × 0.65) ÷ Device Battery Capacity. For example, an iPhone 15 with a 3,877mAh battery can receive about 1.67 charges from a 10,000mAh power bank (10,000mAh × 0.65 ÷ 3,877mAh).

Awesome charging!

I charge my iPhone 16 - 4 times with a single charge. It was recently recalled as one of the batches produced were faulty.

Disappointing Slow Charging

returned this item immediately due to exceptionally slow charging. I am unsure if I received a defective unit or if the entire version is just poorly designed. It was a very frustrating experience, and I cannot recommend it.
