Not the best ever price but still a good deal for anyone looking for high capacity battery charger for their portable electronic devices. Has multiple inputs and outputs. Will charge most phones, Nintendo switch, etc. I have a couple of Romoss power banks (not this one, though) and they work great.
Capacity of 26800mAH at 3.7V brings it to just under the 100Wh legal limit for flights (best to confirm with your airline).
Free delivery for all from Amazon as it is just over the $39 threshold.
