I would get the 737 in a heartbeat. I wouldn't even consider that other Anker. If I wanted a slab design I'd probably get an Iniu.

I went through a plethora of chargers. Samsung devices are finicky about voltage it chooses. Ive tried Anker, Baseus, and Ugreen single port and (multiple ports with 67watt USBC ports). The phone's charging status will Super Fast Charging 2.0 if you exceed 25.0watts. But non of those chargers can reach a peak output of 40watts on new galaxy devices. On my S25 U Anker never went above 29.5 watts, Baseus 35.4 watts, Ugreen 39.2watts All these chargers have pd 15v and 20v and pps range better than the samsungs charger but the phone connects at no more than 9v x 4.5amp or 13v x 3amp. Even though they do fine with 65watt laptop I still want 3+ ports, the Samsung charger isnt worth it for me. Im definitely returning the Anker chargers but am on the fence on weather to keep the baseus or ugreen charger. Yes the ugreen comes a lot closer to full power but gets scalding hot and only saves 3min going from 10% - 80%.
