Batteries lose charge even when they’re not in use. A small solar trickle charger keeps them topped up so they’re ready when you need them.
I received the MHPOWOS 30W Solar Battery Trickle Charger along with a MHPOWOS LiFePO4 battery, and used the panel to charge the battery to full and keep my car battery from draining on a trip.
In this solar battery trickle charger review, I’ll cover the battery, the connection options, my LED light test, and my car battery on an extended trip, the pros and cons, and who it’s for.

The Battery
The MHPOWOS LiFePO4 battery arrived with cushion padding. They make 12V versions in 8Ah, 20Ah, 100Ah, and 200Ah, among others.
Connection Options
There are several ways to hook the panel up. The alligator clips just clip onto your battery. The ring terminals screw onto the posts if you want a permanent connection. And for your car, the cigarette lighter cable goes from the panel straight into the lighter socket.
LED Light Test
I connected an LED light directly to the battery and ran it through the night. During the day, I connected the trickle panel, and it brought the battery back up to full.
My Car on an Extended Trip
I was away on an extended trip and didn’t want my car battery to drain, so I left the panel clipped on. The lights show it’s charging when the clamps go on. You can also use the lighter plug.
Things to Consider Before Buying
- Trickle, not fast charging: It maintains batteries. It isn’t meant to recharge a dead battery quickly.
- Sun: It needs direct sun to work best.
