This thing is an absolute beast. I travel for work with a 16" MacBook Pro and this power bank charges it at full 140W speed - same as the Apple charger. The smart display is genuinely useful, showing exactly how much power my laptop is drawing. Recharges itself in about an hour with my Anker 737 charger. Worth every penny for road warriors.
Finally a power bank that actually supports 45W PPS for my Galaxy S23 Ultra! Most '140W' banks only do standard PD and my phone charges at 25W max. The Anker 737 hits 45W consistently. The display showing input/output watts is addictive - I find myself checking it constantly. It's heavy but I knew that going in.
I have tested this against the UGREEN 145W and the Anker wins on pure charging speed and display features. Both USB-C ports doing 140W is huge - I can charge my Steam Deck and MacBook Air simultaneously at high speed. The only downside is the chunky form factor. If you need slim, get the UGREEN. If you need max performance, get the Anker.
Took this on a 2-week Europe trip. Flew with it in my carry-on with zero issues (86.4Wh is under the limit). Charged my iPhone 15 Pro, iPad Pro, and girlfriend's MacBook Air from a single device. The pass-through charging was a lifesaver in hotels with only one outlet. Display is bright and auto-rotates.
Great power bank but honestly overkill if you only charge phones. I bought it for my laptop and it is perfect for that. The 140W input is the real game changer - my old power bank took 6 hours to recharge. This one is done in an hour. Just be aware it is heavy and thick. Not for everyday carry in jeans.
As a digital nomad, this is my most important gadget. The smart display helped me identify that my cheap cable was only delivering 15W instead of the expected 60W. Replaced the cable and now my iPad Pro charges at full speed. The temperature monitoring gives me peace of mind when charging overnight. 2-year warranty is reassuring.
