Customer Reviews for VEVOR 50W 12V Solar Battery Trickle Charger Maintainer, Mono Solar Panel Battery Charger with Upgraded MPPT Controller & Adjustable Mount Bracket, IP65 Waterproof for Car Boat RV Trailer House Roof

I live in one of the storm prone areas in the US, so any preparation I can make beforehand is, well, smart as hell. At least a lot smarter than sitting and wishing I had done something before the storm. This review is only for the 20w version, this should be well and enough to charge a smaller 12v battery, and it is adaptable to a variety of battery types, but that smaller battery should allow me to charge our phones for a few days as well as, with use of an inverter to pump up my fridge and freezer each day. Hopefully I won't be losing hundreds of dollars in food each storm. For my smaller needs I could likely add the 50w setup and survive well for a week. If you mount it on a wall make sure you have a sense of where the sun hits it, if you have it freestanding either place it in the best sun path, or chase the sun. How long your battery will last will depend entirely on the battery type, and how long it'll take to charge and maintain depends on how much sun each day, etc. Think of like collecting rain water in a bucket, rain comes in waves so you can either run around with your bucket chasing those big waves of rain, or you can set your bucket where the rainfall concentrates. You can set that bucket under your roofs edge or under the branches of a heavy leaved tree. This item seems to be of fairly good construction, I've got mine setup on the roofs edge in a spot that collects a load of midday and a fair amount of morning and evening sun. My battery was charged up from low in a few days, actually a fairly good time for my exposure. I should be able to charge all my devices for around a week easily, which meets my needs. It does seem to be fully waterproof so far, had a couple of intense thunderstorms come through lately and I checked this, I saw no signs of water in it. So, with good sun exposure you are getting a pretty good output, battery life will depend on the battery but mine was charging this battery up pretty good. I might opt for a bigger battery and just

Its a decent 20 watt solar trickle charger. I used it for about 2 weeks on my 99 f150 to keep the battery charged (I rarely use it). It has kept the battery charged. Typically I have to put it on the charger once a month. It being a 20 watt charger it does need more time to keep the battery charged. The stand is great. Looks to be made of aluminum. I sit it right on my hood and let the sun do its magic.

The product LOOKS to be a quality item. However, the packaging is pretty poor for a breakable item. One of the two solar panels I ordered was shattered.

Bonjour ,le panneau est arrivé tordue avec des trous sui laisse a supposé qu'il a déjà été utilisé.

Pas du tout le produit concerné

Would not buy this again. It would not trickle charge my 12v battery(2 amps) this battery controls the opening and closure of my gate to get inand out of the property. Absolute useless.

Bonjour, Pour mon cas, petit mécontentement car sur la rallonge fournit avec le panneau solaire, la polarité du 12VDC peut être inversée si on ne fait pas attention. Il y a un sens pour le brancher, si on y prête pas attention on crâme le contrôleur MPPT....Dommage que ce ne soit pas notifié dans la notice ou bien qu'un détrompeur ne soit pas présent sur la fiche pour éviter cela.

I was hoping for 4 amp.

The wire on the back is flimsy 22 guage with a pigtail 2 pin connector. Go to all the work making a nice set up and cheap out on a pigtail connector. They could have put a mounted connector on the back so ice doesn't form on it in it. Then I look at again and they raised the price 8 bucks.

Het zonnepaneel levert geen 12V, maar 15V in volle zon. Hierdoor is het niet rechtstreeks te gebruiken om de batterij van de schrikdraad op te laden omdat het deze zou droog koken. Ik heb nu een omvormer moeten kopen die de 15V omzet naar 12 tot 13,8:V. Ik heb het paneel nog niet kunnen testen. Het ziet er voor de rest wel degelijk uit.
