Klantbeoordelingen voor VEVOR DC-DC acculader met MPPT 520 W 40 A, laadbooster met dubbele ingang voor zonnepanelen/dynamo's, geschikt voor het opladen van LiFePO4 loodzuuraccu's, 12 V/24 V-12 V/24 V, voor noodstroomvoorziening in campers en thuis.

Zamontowany do samochodu służy jak ładowarka do Fassibot bez zastrzeżeń. Fajnie że ma rewers ładowania akumulatora.

Bin super zufrieden.....Genau gelöst was ich brauche

Llego tal y como ponía en la web. Lo he instalado en un autocaravana, de batería a batería funciona bien, desde las placas solares todavía no lo sé, por estar el vehículo en garage.

This thing is awesome works great with my diesel heater.

I bought this DC-DC charger about a month ago. It seems to be good value for the price. I need to charge my LiFePo battery while car camping. Foldable solar panel did not do the trick, I need faster charging. I was specifically looking for 30A MPPT as my battery peak input is 30A. Now I am getting between 20-30A from car and cca 15A from 350W solar panels (measured at non optimal conditions). Charger seems to be working well, although I see some drawbacks. 1) there seems to be no recognition of car running. No ACC wire, no voltage detection. I did tests on external battery and charger was still consuming 20A at 11V source voltage. I added external voltage sensor which turns input on only when alternator running. 2) Solar seems to be preffered over DC in all cases, it means if there is any voltage at all from solar, it runs solar. Result may be that you are getting 0,5A from solar instead of 30A from car battery. I do not care too much as solar is intended mainly when stationary and it will be physically unplugged while driving. Overall reasonable functionality for good price.

Haven't had to look at it since install which is perfect. Keeping my second battery topped up without impacting the main battery.

Absolutly ok value for the cost. Little bit to loud when the fan is working. Easy to install and use. Great feature with the reverse charging of the vehicles battery.

Bem embalado, chegou rápido e parece tudo bem. Ainda não o experimentei mas brevemente, volto a comentar.

Super

Chegou perfeito, falta instalar. Mas a construção do aparelho indica uma boa qualidade e tds acessórios vieram como descritos no anuncio . Com certeza volto a comprar
