THE MP-23000A
23000mAh capacity Lithium Polymer batteries don't come small and neither does the MP-23000A since it measures 184mm in length, 123mm in width and 18mm in height with a weight of 585g. Worth mentioning is that the top of the battery is covered with a nice brushed aluminum plate.
The difference between some other portable battery models we have here is massive but fortunately the MP-23000A is not as thick as the rest (actually it looks like a small tablet).
You can rotate between all the available output voltages and check the current battery charge via this button and the LCD screen at the top of the device (to rotate between voltages you need to keep the button pushed for a few seconds).
Right in front of the LCD screen we see the two USB charging ports (5v/1A, 5v/2.5A) and the DC In/DC Out ports.
To know which is which XTPower has labeled them at the bottom of the battery.
The electrical specifications and country of manufacture are also present at the bottom.
The MP-23000A fully charged and good to go.
