Customers say
Customers find the solar charger easy to use, taking less than 5 minutes to install, and appreciate its functionality, particularly for maintaining truck and mower batteries. The build quality receives mixed feedback, with some finding it well constructed while others describe it as cheaply made. Power output and battery life are also mixed aspects – while some report no dead batteries after long trips, others mention the panel draining them, and while some find it good value for money, others say it’s not worth the price.

Exactly as advertised
I recently purchased the 10W Solar Battery Charger, and I am extremely satisfied with its performance. The charger is suitable for keeping vehicles/boat batteries charged during weeks of disuse, without the need to disconnect the battery or have someone start the vehicle periodically. The indicator light on the back allows me to observe the charging state, and itâs waterproof, making it safe to use outdoors. The 10W monocrystalline solar panel uses trickle charging to charge the battery without causing overcharging, and the built-in blocking diode prevents reverse charging without extra maintenance at night, ensuring protection against damage. The panel works even on cloudy days, making it a reliable source of power. The upgraded PCB and addition function of reverse and overcharge protections ensure that the panel is still working normally, even if it’s not possible to test the open-circuit voltage. The charger is easy to install, equipped with an SAE cable that can be plugged into the cigarette lighter port or connected to the battery terminal posts with the alligator clip. The connection can be completed within 3 minutes, making it suitable for use in cars, trucks, boats, lawn mowers, motorcycles, trailers, dump trailers, tractors, RVs, vans, campers, ATVs, utility vehicles, and more. Overall, I highly recommend the 10W Solar Battery Charger to anyone looking for a reliable, easy-to-use, and effective solution to charge their battery and keep their vehicle or boat running smoothly.

Nice solar charger.
This is my 3rd solar charger. I hang it from magnetic clips. I use them on my UTV and ATV’s stored in a trailer. 100% happy. I also purchased a long extension cord and it works great.

Great product ð
It will not charge a dead battery, it is not intended to. It simply keeps a good battery charged on vehicles that sit without use for a long time.The product itself is great, I bought 3 of them.What happened is, the first 2 I bought were delivered but at 2 different prices ð¤so I called Amazon and was told they can’t help me. So I ordered 2 more at a discount for buying 2 and I returned the higher priced 1 still new in the box. Did not seem to me to be the most efficient way to handle it but, that is humans!The 2nd problem was that the delivery person left the package OUTSIDE instead of INSIDE the safety of a closed in screen porch ð. I live in a ground floor house with no steps but yet the package was left outside in plain view from the street and in any possible weather. They simply ignored my delivery instructions and all forms of common sense and respect. If I delivered, I would put things inside a porch whenever possible just for common sense and respect! I can’t understand this way of thinking, can you ð¤???

You wonât regret it.
6/5 stars. I love these things. I have purchased 3-4 of these for personal use. Iâve had 2 outside for a few years now, and one thatâs been in my truck for 2-3 years One for my truck that get driven every two weeks. One for a 4 wheeler. One for a tractor to keep the battery topped off, affixed with magnets. Itâs nice knowing something will start every time. I canât recommend these enough. The only thing I could say is maybe give an option for rings instead of gator clips, and the option to pic up the threaded magnets for these in a bundle

ONLY works in summer AND full sun EDIT!
I originally tried using this panel for my truck and it made my batt. go dead. I thought maybe i left the lights on or something so i jumped, charged, tested batt. and tried again. Same result.So i tried using it as a “power bank” recharger but my “power bank” is a brand new off the shelf 690cca car battery. I drained the batt. to 11.6v from use then disconnected the batt. and hooked up ONLY the panel. All day with no clouds, solar panel squared off to the sun. From 8a.m. to 6p.m. (Yes, it is winter. I understand..) The batt. dropped to 10.9v and was so brand new that simply leaving it sit with nothing connected it recharged itself to 12.3v by the next morning. Figured maybe indid something wrong so i tried it again. Same batt. same result. It does not produce enough power in winter even with no clouds. So only useful in summer months. (if at all. Yet to be determined.)EDIT: Turns out i got a broken one. They replaced the panel at no cost to me (besides my batteries the 1st panel killed…)It is not strong… or quick…. (or very useful)With just this panel charging a 12v 12ah/20hr U.P.S. battery it took almost all week.. It did ultimately charge it full but it took well over enough time to do it.I wouldnt really consider this to be much of a trickle charger. Barely a maintainer.EDIT: I increased my rating from 1 star to 2 stars based on the only real use i can find for a 10w panel that automatically shuts off.(Not just for a bit either. It shuts off UNTIL you disconnect and reconnect it manually once it hits ??? Some predetermined random voltage it seems like half the time.) I digress…The edit is for this purpose;If you use this panel as a makeshift battery charger i.e.- AA,AAA,C,D, and 9 volts(<

I don’t drive my car as much as I should and therefore have been using a 240v trickle charger to keep it charged but it isn’t convenient rolling out an extension lead.This solar charger has solved that problem and is working very well.The cable runs under the seals on a closed door and under the bonnet with no problem.

dopo averlo provato qualche giorno, per tenere in vita la mia vecchia batteria dell’auto (di quelle costose fatte per essere continuamente caricate) ho deciso di prenderne subito un’altro!! In pratica il pannello lo danno per 10 watt, ovvero 700-800 milliampere , il voltaggio a vuoto si aggira sui 19 volt, con il carico arriva sui 14 circa, nel mio caso ho un consumo fisso intorno ai 400-500 milliampere (dovuto anche all’antifurto tracker gps) quindi se ho la batteria in perfetta forma (quasi mai visto che l’auto fa pochi chilometri e sta ferma per 1 settimana) si riesce a non rimanere a piedi….ovvero non si carica ne si scarica…ma ricordiamoci che adesso il sole e’ molto forte!! e quindi abbiamo quei 10 watt detti belli pieni.Prendendone due….collegati in parallelo, mi assicuro di avere un 1500Mha in uscita verso la batteria quindi, almeno 1 ampere per la ricarica della stessa, anche nei giorni di meno luminosita ho abbastanza carica di mantenimento e una leggera ricarica. Prodotto promosso al 100% molto ben fatto anche nei collegamenti , e ovviamente Amazon sempre veloce e precisa.
