Worked briefly unfortunately.
Missed our return window unfortunately, buy with caution, unit worked for a few weeks and will now only output 12.08volts 🤷 sooooooo broken but it'll make a good door stop 😞

Great bit of kit.
Arrived quickly and works great. Make sure to use mega or nano fuses as the resettable one I first tried led me to think the charger was faulty as it was only allowing 3.5amps through it. Bypassed the fuse and it was then working perfectly at outputting the full 60amps.

Dc to dc charger
Lost points on instructions. But dose a really good job of charging the liesure batteries. Can't just connect negative to anywhere. I need to run in another negative. Cable to front of van is picks up a feed from itself and keeps charging, until turned off then starts again as soon as van started. Not great at wire sizing. As information hard to find. I just used 16mm cable a bit of over kill.

Used for almost a year, still working well!
The dc to dc is still working as it should nearly a year on from fitting to the van. With a small solar panel on my roof and this charger I never have to worry about my leisure batteries, even in winter.

Het enige wat mij niet bevalt is het geluid van de ventilator. Ik ben gewoon best kritisch daarop hoor. Maar in mijn nieuwe camper heb ik heb ingebouwd in een kastje en hoor ik niets meer. 40 ampere is genoeg om de accu snel bij te laden

Po dwóch miesiącach użytkowania przestała działać... Serwis gwarancyjny jest nie wiadomo gdzie i nie wiadomo jak zgłosić produkt na gwarancje, ogólnie polecam się dobrze zastanowić.
