10w Solar Trickle Charger

Great little panel which was pushing out 13.8v on an overcast day. Keeps my battery topped up perfectly, also stopped my car alarm from sounding due to voltage drop from power drain

Good product for the price. Connecting cable is a good length but the cigarette lighter connection is very tight. Trying to pull it out of the socket resulted in pulling the whole fascia out as well. Panel seems to charge well in strong sunlight.

An excellent value item that works well. I keep it in place on my wheelchair car to ensure the battery is always ready for use. As a drive from wheelchair car, it uses a great deal of energy from the battery and this charger is ideal to keep it in full charge.

I bought one of these and after fitting it was impressed by it. So I bought another for my wife's car. This one had a technical issue, but the company shipped a replacement right away - so kudos to them for that. I don't see what a few people are complaining about with the connections, I've installed both without any issue at all and there a variety of connections for different situations. Highly recommended and more powerful than most of the trickle chargers out there. I'm a happy customer.

I bought this despite some bad reviews. My car only does short miles so was having to charge battery constantly. This kit came complete and ok. Being a car mechanic the wiring and everything is ok and not dangerous as others have reported. I've hard wired it to my battery and not used the 12volt plug as mine aren't live unless the ignition is on. There's 2 meters of cable and this is plenty to route it into the car and install it in the windscreen. I have enough cable to unplug it on the dash without opening the bonnet. All in all a good product so long as it's permanently fixed in place.

Hooked it all up and cigarette lighter plug light was lit and plug into car but still got a flat battery so returning it and asked for a refund

Technology has moved on, l am impressed by the power of the panel, at 10 Watts. The size is small and lightweight on a Plexiglas base where Several different layers are printed on top. This is a printed laminations about 0.8mm thick. It has a toughness and a little flexibility, however l would not want to treat it with any roughness or vibration wear. However it is only 8.8 grams. No plastic cover lens, plastic frame, seals. Closes thing to compare to is a printed circuit board, I'm sure you would have to use a blade to do any real damage. Accessories: l bought it because of these to be honest. Mainly the extension lead with the simple barrel plugs. The ringed pigtails are the second option, but under close inspection, a cheap thin wire, with a hard insolation plastic. Meaning it will not relax from packing, no cold or heat resistant, work hardening and breaking is very possible. The Clamps and pigtails are cut ridiculously short! I mean changing bolts over to point inward which clamps aren't. If you have a large battery you will have to solder new wire in, l suggest a 2amp inline fuse, as worthy upgrade. Second issue the box on the back, a cheap and nasty battery box. Though the connection box gives you access to the protection board to add better wire for engine bay and external use. Third issue, the suckers can only be used on the front of the panel, to mount on the inside of the window, the cheap box is taller than the suckers. Duh! Pro:- lightweight 8.8grams, weather proof panel, powerful, extension cable at 8ft small barrel Plugs at both ends. Con:- accessories will not fit every battery out the box, no fused line even though the wire is a hazard, plugs aren't weather proof, saved money on the accessories totally letting down the panel. Buy it knowing that you will either break the accessories first and have to replace or repair, or do it first to fit your purpose. Conclusion :- inside use only, mount on window, dash, sun visor. Use the cigarette socket, if closed with ignition off get an automotive electrician to open it, or run a new socket with fuse and correct cable. I have chosen to get the hidden 12v output opened, and stick it to the moon roof, which still allows me to close the blind. The cable drops at drivers seat back, and tucked in chair pocket. Simply pull at barrel plug on board and you have removed any cable. I'm disappointed at the quality, but it's weight and size only allowed for one type of setup, and made it more expensive. However its livable, turns out it will be a better all year round spot on the moon roof. If blind had not closed it would have been sent back, but to be fair no other option was available here. Note... Honda CRV EX 5th Gen 2013.

I bought this in October 2020 because I'm disabled and only drive short distances a couple of times a week, not enough to keep the car battery charged, and I was fed up with having to use a jump starter on the car and drive a 30 mile re-charging loop every few weeks. I have no garage or off-road parking, just park by the pavement on the street, so can't connect a trickle charger to the mains, so I was looking for some means to trickle charge the battery contained within the car, thought I'd try a solar trickle charger and picked this one Short version - this has done the job, and since getting it I've only had to use the jump starter on a drained battery once in 21 months, and that was after I'd left the sidelights on overnight by mistake. So, it's done a good job and I'm very happy. The only two minor niggles (not anything like enough to make me unhappy with it) are the way certain parts come off. The lid of the little box containing a pcb on the back of the panel is so loose it tends to come off when I move the panel and I have to refit it; and twice the end of the cigarette lighter plug (end cap, spring, fuse and connector) comes undone, and I don't notice until I can't get the plug in the socket, then realise what's happened, fish the bits out of the socket and reassemble.

permet le MAINTIEN de charge de la batterie,dommage qu'il n’existe pas un kit pour pouvoir en couplé plusieurs et ainsi faire un vrai chargeur de batterie solaire. fonctionne même sans grand soleil.

Excellent

Nachdem ich für ein Arduino-Projekt schon mehrere andere kleine PV-Module gekauft habe, die nicht genügend Leistung gebracht haben, habe ich nun endlich diese Modul gefunden, dass genügend Leistung hat , um eine 12V 7,5 Ah Batterie zu laden. Das Modul besteht aus einem Kunststoffträgermaterial, was relativ flexibel ist. Allerdings ist das Material auch über den Solarzellen, was die Leistung etwas schmälert. Andereseits ist das Modul dadurch wetterfest gekapselt. Das Modul verfügt auf der Rückseite über eine Ladekontrolle, die verhindert, dass angeschlossene 12 V-Akkus überladen werden. Was mich etwas irritiert, ist die Tatsache, dass das Modul bei Sonneneinstrahlung ein leises Summen erzeugt. Vermutlich kommt das von dem integrierten Laderegler.

I originally bought this panel with the idea of putting it on my shed roof and using it to keep my lawn tractor battery topped up. My tractor is old and the charging system is pretty much non-existent, but since the battery is mostly used only to crank the engine, I can get through an entire season with it. Almost. The battery, like the tractor, is starting to get a little tired. I've found myself having to take it out and charge it to get through this season. Let's face it, this battery is on its last legs, and I'm just hoping I can get through the next few weeks with it. So I bought this solar panel and immediately ran out of time to install it on the tractor. Instead, I stuck it in my truck. My poor old truck sits unused for weeks at a time. It always starts, but it tends to crank pretty slowly because the battery draws down between uses. This charge/discharge cycle is hard on both batteries and alternators, and both have gotten too expensive to abuse and potentially damage. Since I don't drive the truck much and I don't want to run a battery tender outside, I decided to repurpose the solar panel as a truck battery maintainer. For this, it works perfectly. The panel mounts to the inside of the windshield with four suction cups. Easy to put on, easy to remove when I want to drive. The panel itself is very thin so I have to treat it gingerly. I wish I could find a solution that didn't involve removing it every time I want to use the truck but so far I haven't. We'll see how it holds up over time to being repeatedly installed or removed. I envision flexing it just a little too much and hearing a fatal cracking sound but so far it's been fine. The panel uses SAE connectors which allows you to attach to the cigarette lighter dongle, alligator clips, or dedicated ring terminals. I use the cigarette lighter adapter because the lighter socket is live on my truck all the time. If your vehicle disconnects the lighter socket when the ignition is turned off, you'll have to figure something else out. SAE connectors are hermaphroditic connectors. That means that two SAE connectors will plug together, but the polarity will reverse (IE the "positive" terminal of one will feed the "negative" terminal of the next one). I triple-checked that the panel would not be wired in reverse polarity in my installation. The panel has a reverse-polarity indicator but I prefer to use a multimeter and see for myself. You can get polarity reversing adapters if you need them but I didn't. Last time I went to use my truck, the panel had been on and charging for about a week. The truck cranked just as quickly as if I'd put the battery on a dedicated charger. I haven't checked current output or state of charge of the battery, but my seat-of-the-pants analysis tells me that it's keeping the battery topped up. Impressive considering we've had a few cloudy/rainy days this week. We'll see how well it works over the winter. In all I'm impressed with this panel. It's a simple solution that (so far) seem to work well. It's WAY less expensive than buying a battery so if it continues to work, I will consider it money well spent. I'll update once I've used it a while longer.

I've had a few times where I came out to start my car and the battery was dead, But that was because the dash cam had drained the battery. My power port never shuts off even if I turn the car off. The only way to turn it off is to disconnect the battery or pull the fuse. And it's a Wi-Fi – cam so I was searching for a Wi-Fi hotspot and on top of that it's always recording, It never stops. Show you this. You just ate a lot of power. With this trigger charger, it has just enough juice to run the dash cam without it draining the battery completely. I've been able to leave it for 5 days and have no issues. Used to be only about 2 days and I couldn't start my car. I haven't tested it beyond 5 days cuz frankly I'm tired of asking my neighbors for jumps. But it works great. It's full of power via the power port because yes I have two of them. I mean why wouldn't you always be on in a car?.. It's actually one of the many things here that works as advertised. I haven't been a meter to it yet, but I think it pushes a bit more than 10 w in direct sunlight, but considering my car is usually parked beneath an awning, it still provides enough power to power the dash cam and keep the battery charged so that it'll start whenever I need it. So it was a great value. Definitely worth the money paid. And I would definitely recommend it. The only issue is it does get quite hot sitting in the sun but it is black and I live in Arizona, those are two things that do not get along. If they can make it white it'd be perfect.
