Works great glad i finally got one to charge my batteries
Convenient small charger that keeps a spare readily charged for my Fenix WT25R light.
Good as a charger, not so useful as a battery pack with a S21 5G.
Charges 21700 just fine.
As a battery pack using the USB-A port it can't keep up with the power demands on my Samsung Galaxy S21 5G. For example, 10% charge remaining on phone. Plug in the supplied cable to the ARE-X1 and the phone. Phone indicates slow charging and with the display on (using to navigate) power level continues to decrease.
If using the ARE-X1 with a USB-C cable at both ends the phone charges the battery in the ARE-X1 only. On the phone there are options for the "USB Settings". However "USB Controlled" cannot be changed from "Connected Device" to "This device" to set "Charging phone only" mode. To be clear, my phone is charging the ARE-X1 only - no way to make the ARE-X1 charge the phone.
3 star due to half the functionality isn't available.
charged the battery fairly quickly
