THE AL390

The enclosure of the AL390 weighs 638g, is made out of hard plastic and measures 186mm in length, 129mm in width and 28mm in height (thickness).

This is a large power bank but certainly not the largest and to showcase this we placed it right next to several of the models we're using in the lab.

The on/off button is placed at the top of the device and can also be used to check the current charge of the internal lithium-ion battery thanks to the 4 blue LEDs placed next to it (Xtorm claims the battery comes pre-charged but obviously noone should wait for that to last many months).

Moving on the left side of the device we find the DC charging input.

At the front of the AL390 we see the two 5v/2.4A charging USB ports, AC charging on/off switch and a charging LED indicator.

The AC port is covered by a hard plastic cap so you will need to remove it.

You can use the AC port with compatible EU plugs but Xtorm also bundles a travel adapter which can be used with EU/DE, UK and USA plugs.
