Works great for my trailer battery

Great functionality. Easy to use. Works very well.

Great little solar panel for keeping my RV battery topped off. The MPPT controller is easy to use and does make a difference. It comes with all the cables and clips you need. Lightweight but feels sturdy. Perfect for trips when I don’t want to run the generator

I purchased the 50w solar charger for my Porsche Boxster. I wanted a charger that lets me know the % charge and won't overcharge my battery. This unit does that along with a 1 year warranty. The company has been around 20 years and this is a quality product. It is easy to use and multiple ways to attach to the battery. For me I am using the battery terminals as the easiest way to attach the charger. Customer image

Leider passen die beigelegten Schrauben nicht durch die Verkleidung des Monokristall. Durch den Kleber sind die vorgegebenen Löcher zu weit eingeschränt. Ist aber lein Hinderungsgrund für den Einsatz. Sonst ist die Funktion gegeben

The Vevor 20-watt, solar 12-volt battery charger can keep your 12-volt car (and other types of batteries) charged. It maintains a trickle charge and can be used in most weather conditions. High-efficiency panels can maximize the charge efficiency even in lower light conditions. Easy to use, make sure the clips cable is attached to the charger and attach the clips to your car's battery. Aim the charger in the general direction of the sun and let the charging begin. The hardest part of using this device is determining where to place the solar panel. Direct sunlight, especially in the summer, is not the best choice. What you want to find is a spot giving you the most sunlight exposure with the least amount of radiant heat possible. Also, avoid any spot where the charger can sit in pooled rain water. It only has a waterproof rating of IP65 which means it is dust-proof and can resist water spraying on it, but cannot be submerged in water. It is by no means high-speed, but, while your vehicle is parked, it can maintain the charge in its battery.

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.
