looks like Zendure has stopped support for their small powerbanks : the firmware upgrade software for the supertank pro is nowhere to be found on their site ...
It's pretty useless to measure a multiport charger only charging one device. I doubt that for instance- it could output 100w X 2. And what are the numbers when charging 3 & 4 devices simultaneously... Ports # 3&4 @ 18w each fairly useless for non-budget phones.
Even @ single max 100w not that great with some phones @ 150w \ laptops 200w.
I don't think this is newsworthy,ravpower has had a 90watt 30,000 wh smaller and much more portable bank for over two years.I can personally vouch for the 1mbp 16 inch full charge and portability.
90W 2-Port PD 3.0 + QC 3.0 Power Bank Charger 30000mAh Massive Power
It's not exactly cheap at $169 USD, but it'll probably be the best and only power bank you'll need. The informative OLED display in particular helps separate it from most other power banks in the market.
