I regularly work from cafés and co-working spaces where I don't always have access to outlets. This has enabled me and my 2017 MacBook Pro (with a degraded battery) to work for about 2-3 more hours.Love how small it is; would love it more if it gave me 4 hours, but that's me reaching for something to complain about.

I have had the Zendure Supertank for pretty much a month now. I can say, it has met/exceeded all my expectations. First, When I first took it out of the box, it struck me how smaller and compact it is. I can literally wrap my hand around it. But I can’t say it’s pocketable. Pictures don’t really do justice to show how small it is. Second, love that there is a LED display to show the battery level. Third, it comes with a 100W USB-C to USB-C cable! Lastly, the build quality of the battery is great.I personally have tested it to see how many times it can charge my laptop and phone. I have a HP Spectre X360 laptop(late-2019), which uses 65W to charge. The HP Spectre requires fully charged Supertank to fully charge my HP Spectre. I have been able to charge my phone(Pixel XL) about 5 times before fully draining the battery. Also, there is a low power mode which you press the power button twice to activate the LED display will alternate between “Battery Level” and “X”. I use this mode to charge up my headphones, and my Smartwatch.I have a 65W PD charger (AUKEY Omnia) which I use to charge up the Supertank. A full charge from 0-100%, takes about 2-3 hours. The Supertank does take in 100W(I don’t have a 100W charger to test). Having fast charging on an external battery is a huge plus. Also, there is pass-through charging, which does work.There are somethings that I think could have been a little better. For example, I think that the battery’s LED should turn off while charging to improve efficiency. Also, the 60W USB-C port on this doesn’t support input charging. These things are minuscule and aren’t dealbreakers by any means, just my opinion.Conclusion:Well, with a 27000mah and an included 100W USB C to USB C cable. You no longer have to be locked to a wall. Definitely, the best external battery that I’ve owned!P.S: Remember to take off the plastic film off the LED screen. Or else, you’ll think that it scratches up easily which it doesn’t.
