Why We Love This Deal
The dark side of owning a car jump starter? Its battery can die too. Plus, jump-starting a battery over and over again can degrade its lifespan. That’s why it’s sometimes nice to take a page out of the plant playbook and gather energy from the sun with a solar panel to keep your battery charged over time.
The good news is that Amazon is selling one at 53% off: The Voltset 20W, 12V Solar Battery Trickle Charger Kit is now just $28, its all-time low price on Amazon.

What Shoppers Should Know
- Maximum Volts/Watts: 18V/20W
- Connector Type: SAE to SAE
- Works With: The panel works with 12V batteries in Lead-Acid and Lithium-Ion categories, such as AGM, Gel, SLI, Marine Batteries, and LiFePO4, plus NiCd and NiMH batteries.
- Included Components: Solar Panel, Charger Controller, Adjustable Bracket, O-Rings, and Alligator Clips
- Best Use Case: Ideal for long-term battery maintenance, keeping batteries charged during periods of disuse.
This set’s purpose is to keep your batteries charged, even with long-term down periods. It comes with a mounting bracket that affixes to cars and boats, allowing the panel to be tilted to find the perfect angling for the sun’s rays. From there, power trickles down to the battery, giving it extended health and life on the go.
The panel’s waterproof controller has a simple power in, power out structure with LED lights displaying when power is coming in and when batteries are full. Connect the controller to 12V Lead-Acid, Lithium-Ion, Nickel-Cadmium (NiCd), and Nickel-Metal Hydride (NiMH) batteries with either alligator clamps or o-rings for a slow trickle of power that keeps batteries active and charged over the long term.
What Shoppers Are Saying
One shopper detailed using the trickle charger with a dump trailer. “This 20W solar panel keeps the battery topped off so the trailer is ready to use at any moment. After a number of trailer dumps, putting this solar panel up, even on cloudy days, will have the battery back up to full charge in less than two days. It is an excellent little panel that does way better at maintaining the battery than I imagined.”
Another shopper revealed that the panel made them a very happy camper in their, well, camper. “This little sucker works great! Keeps my battery in my camper nice and charged. Plug and play!”
The Voltset 20W, 12V Solar Battery Trickle Charger Kit is now at its all-time Amazon low price of $28. Get yours while you can, because the deal won’t stick around forever.
