Is it normal for the display on this power bank not to show the maximum power output all the time?

Smart temperature control dynamically adjusts output to prevent overheating. This small portable charger delivers full power when your device is low, then reduces power to safeguard battery life and boost efficiency.

Why does my power bank sometimes get hot while charging?

Given that this battery is only 0.61 inches thick, it responds to temperature changes much more noticeably than bulkier devices. Furthermore, fast charging causes a certain temperature rise, and using the device while charging also elevates its heat.

Why does my power bank charge my device fewer times than expected?

It can provide 50%-70% of its capacity to other devices. About 30%-50% of capacity is lost due to circuit heat generation and voltage conversion. Generally, the devices receive more power when charging in standby mode than when charging while in use.

Does it support pass-through charging?

Yes, our power bank supports pass-through charging. You can charge the power bank while it is connected to the charging device.

Can I bring it on the plane?

Yes, this 10000mAh power bank complies with the U.S. Transportation Security Administration (TSA) regulations for carry-on items (<100Wh).
