Sorry if I’m repeating what’s already been shared (I skimmed and didn’t see it in this thread, but it may be somewhere else), but I backed a couple of products from Zendure on Kickstarter over the years, one of them being their SuperTank Pro:
SuperTank Pro 26800mAh 100WPD Portable Power Bank – Zendure
I’m a Canadian, living in Australia, and I have family in Portugal, so travel adapters are huge for me, and I was looking for a way to reduce the amount of cables and crap that I travel with. Between the SuperTanks, the Passport adapters, and the SuperPort, I’m super set up for power that travels super easy. Also, so long as my laptop charges with USB-C (or I can use an adapter), then the SuperTank (and Pro, I have both) easily powers my laptop for when I’m working out of the office or away from home.
