Review: Works well for Ram Dually - 3 years of use - Here are my observations. First off I park facing a 2015 Ram Dually with the 6.7L Cummins facing due east - this gives me the front and side windows to mount two in during rhe winter months, and the side window alone to mount one in dyring the summer. The solar cell mat sits well in the passenger window by itself. And I lay the other in the front dash. These also stay hooked in full time - never being disconnected (stow them on the floor between the passenger seat and the door at the belt base to keep them upright). Truck has an Aftermarket Car Alarm that tends to work the batteries moreso than a normal truck. Truck stays sitting for a week at a time (during summers up to a month, and maybe once or twice like this during the winter) in Buffalo, NY. Batteries are 2-each set of $350 Odyssey H7 Batteries, Absorbed Glass Mat (AGM) P/N ODP-AGM94RH7. First off, I run one solar charger in the summer and two in the winter. What I found was that during the winter, a single one was OK, but due to the amount of snow buildup (and just the lower amount of sun), that I needed two running together to top off the battery. And, that and the fact that they tend to go bad in the winter and I couldn't risk loosing charge on a 4 week run and flatten $700's worth of batteries. Also, Batteries always tend to go bad in single digit weather in January and February. Observations: Brand new I could get the charge to 12.4V during the summer during the first year. The winter's, it's more like 11.8-12.2V; but it honestly couldn't seem to keep up, finding it after two weeks straight at 11.4V at times with just the single charger. On year two I noticed the batteries couldn't seem to go north of 12.2V in the summer. In November, I bought a replacement solar charger as the first one finally went; but then I also bought a second one due to the likelihood that while sitting for several weeks straight, that this one charger failing could take out both of these batteries. So now with two Solar Chargers installed, with a dual-headed 12V splitter (Power Drive PD9223BL 2-way 12V Adapter), I was able to get to 12.2V, and even 11.8V with the windows covered (the side window less than an inch, but the front burried) - honestly, the solar cells still charge somehow. So during rhe winter of 24-25 (and at this time of writing), this configuratuon has worked flawlessly!!
Review: Reliable, Easy-to-Use, and Super Efficient! - bought the OYMSAE 30W 12V Solar Trickle Charger to keep the battery on my truck topped off, and I’m honestly impressed by how well it performs. It’s compact, lightweight, and super easy to set up right out of the box. Whether you use the cigarette lighter plug or the alligator clips, installation takes just a couple of minutes—and you’re ready to harness the sun. I’ve been using it for a few weeks now and it keeps my 12V battery healthy and fully charged without overcharging. Even on cloudy days, it still delivers a consistent trickle charge. The built-in smart controller with overcharge protection gives me peace of mind, and I love that it’s completely maintenance-free. It’s perfect for cars, trucks, boats, RVs—basically anything with a 12V battery you don’t use every single day. I keep mine on the dash and let it do its thing. No more dead batteries when I come back from a trip! If you’re looking for a durable, portable, and efficient solar battery maintainer, this is it. Totally worth it.

## Features

- 22 % High Conversion Rate:Monocrystalline solar battery charger use ETFE , with a light transmittance of up to 95 %. The 30 W trickle charging mode is an ideal choice for low-cost maintenance of your 12 V battery power
- Intelligent Protection:Combined with built-in charging microprocessor technology, it will not overcharge the battery when fully charged during the day, and prevent the battery from reverse discharge at night
- Charging Visualization:The indicator lights are used to help you understand the charging status: the blue light is on (in the sun), the red light is on (charging), the green light is on (charging completed), three indicator lights are off (a short circuit occurs). You can check the connection in time when the solar energy fails
- Plug and Play:The three -pieces SAE cable included with the solar panel kit allows you to have more choices in charging methods. Plug and play, even for inexperienced novices, fast connection can be achieved
- Sturdy and Durable:Waterproof solar trickle charger, adding CPB as the bottom plate, reducing the risk of reducing the efficiency of the solar panel due to panel breakage

## Questions & Answers

**Q: Will this solar charger revive a completely dead car battery?**
A: Designed for 12V trickle charging/maintenance, it prevents discharge but can't revive sulfation-damaged batteries from long-term drainage. Optimal use requires 6V+ residual voltage.

**Q: How to confirm if it works with my vehicle?**
A: Compatible with all 12V lead-acid/AGM/LiFePO4 batteries (cars/boats/RVs). Our 30W upgraded model handles larger batteries up to 150Ah. Just connect via SAE port - zero wiring expertise required.

**Q: Does it drain power when not in sunlight?**
A: The zero-night-drain controller terminates charging at sunset and activates reverse current blockade. Energy loss is 85% lower than basic models according to lab tests.

**Q: What makes your charger safer than cheap alternatives?**
A: Features include ✓ ETFE-coated monocrystalline cells (IP67 waterproof) ✓ Triple-protection IC: Overcharge/Short-circuit/Reverse polarity ✓ CPB impact-resistant base (tested for 50km/h debris collisions)

**Q: How long to charge a standard SUV battery?**
A: ▸ 30W model: Fully charges 80Ah battery in ~5 days (2-4% daily trickle) ▸ For faster charging, pair with our 45W PRO Series (ideal for RVs/campers)
