Dave's Stupid Web Comic Great power, little responsibility
20A
It's working great. It powers my laptop and charges my phone when others failed. It doesn't draw a large amount of stand by power, so I leave it on all the time. I'm in a minivan converted to an rv with around 100ah of battery capacity

David D. Works great
20A
Easy install, seems to do the job well. Made for a much easier trip when facing long travel days that otherwise would be draining the camper house battery bank.

Works really well. Easy to install and runs just fine. Like that it has a fan for cooling as to not have it throttle during hot summer days.

Works well but one wish that it could be set from the get go to only do charginig when alternator is running. Now one needs to create an own D+ signal

Ho segnalato il problema di funzionamento del DC DC al centro assistenza. Non hanno risolto il problema ma hanno preso solo tempo.
Il prodotto non rispecchia le caratteristiche tecniche riportate. Attendo ancora la risoluzione del problema.

Chargeur DC DC 12v 20A ne sort pas l'intensité nominale de 20A mais 6.4A. La charge se fait en 3 fois plus de temps. Sinon les dimensions sont correctes et principe et bon, sauf que le mien ne debit pas assez.

I did reverse the polarity of the output terminal and the device was ruined. I replaced the inside fuse and device keeps blowing ints internal 20amp fuses.
