Only in one review: Capacity 3670 mAh (M18 battery); Energy 65 Wh (M18 battery); Resistance 15 mΩ (M18 battery); Weight 655 g (M18 battery).

M18 battery: The case and protection are decent, but capacity is about 4 Ah instead of the claimed 6 Ah; the author advises against buying it.

Power bank: The device is convenient and usable, but measured capacity is nearly half the claimed value; the author is unsure it is worth buying.
