I bought this charger so that I could charge faster at places with 208 or 240 V outlets. The build quality is excellent, the size/weight is excellent, the long cable is helpful, and it's super easy to use without involving the app. I separately purchased a NEMA 6-50 to NEMA 14-50 adapter and am able to use this with welder outlets at work. I've been using it for a couple weeks now, and it doesn't get hot and has had no issues charging my Bolt at 24 A (the guys set me up with 208 V/30 A circuit, so I've been running it just below it's maximum output). I have not used the app that works with this, so I have nothing to say about that. The display provides line voltage, current being delivered, and cumulative kWh, which is all I need to know. For the price you can't beat this charger.
