It works
I have a 2000 Ford Ranger pick-up truck that sits in our driveway. I use it for projects around the house – hauling brush, building supplies, garden supplies, etc. so it often sits for weeks without being started. Often, in the winter, we have temperatures around 0° F or lower (I live in Minnesota). Since the battery sits without use it slowly discharges and requires a jump to start on cold days. I can jump start it but I would prefer not to do so on a below zero day. I decided to try the solar trickle charger to see if it would solve my problem. We just had a stretch of cold weather. This morning it was -13° F and warmed up to -5° F. so I decided to test the battery by starting the truck. It didn’t start right up but the battery kept spinning the engine until it started. I am impressed!Things I like about the charger: 1) It works; 2) I had considered an electric trickle charger but that would have to be plugged in and use electricity. The solar panel sits in the front window of the truck and is continually charging the battery as long as there is sunshine. I just unplug it when I use the truck; 3) I have the charger inside the truck attached to the front window with the suction cups that come with the unit and it charges without any problems. I don’t have to put it on the outside of the truck; and 4) it is an ingenious solution to my problem. I am pleased with my purchase!

Easy setup, works just as advertised.
15W charger working just as advertised. Well made, sturdy, simple setup. I drive very little, so battery tends to drain over time. Have it mounted on the deck behind my back seat, plugged into cigarette lighter socket in center console, secured with 3M VHB sticky pads. LED indicates it’s charging the battery even in cloudy weather. I contacted support about leaving it connected while driving and they responded quickly confirming that would not cause any problems with the charger or the battery. So far so good. I’ll update with any changes.

Works pretty good
I would say it works well but not perfect. I have a car that sits a lot. This will maintain it pretty well but I’ve found it completely dead too. Probably best if you still start the car once a week or so.

Great for rv or boat batteries, but may overcharge if left on too long

works great on V8 SUV’s
works great I have it on my SUV as I don’t drive much and works great keeping the battery charged up I was wondering if it would work on a big SUV but does work great have it plugged in the 12v plug inside the truck as it isn’t switchable and seems to charge from there the only thing I could be better the leads most of the wire is on the solar side wish they where reversed there for more cleaner install

Trickle charge my generator
Use it to trickle charge my backup generator, before I would have to manually start the generator each month. Now I just go out turn the key and it fires right up. Great product and it works!

Seems to work, but light that indicates fully charged does not come on
I’ve got it in the window of my second vehicle. The indicators for power and charging work fine though it never lit up to indicate fully charged—so after a few days I checked the value of the battery and it was over 12 v. And whenever I check, the battery seems to be good. The unit is probably it is working, but is not indicating its own success.

I recently purchased the POWOXI Solar Battery Charger for my car, and it has been a fantastic investment! The 7.5W solar panel is highly efficient and does an excellent job of maintaining my car battery’s charge, even in less-than-ideal weather conditions. The charger is easy to set up and comes with all the necessary accessories, including suction cups and a cigarette lighter adapter.The build quality is impressive, with a durable and weather-resistant design that ensures longevity. I love that it’s environmentally friendly, harnessing solar energy to keep my battery charged. It’s perfect for those who don’t drive their vehicles daily or for extended trips where access to a power source may be limited.Overall, the POWOXI Solar Battery Charger has exceeded my expectations in terms of performance and reliability. It’s a great solution for keeping your car battery maintained and ready to go. Highly recommend it!

I use this to keep the battery on my ride-on mower topped up. The shed has no electric so this is the ideal solution. Very pleased!!

インジケータは充電状態で緑、電圧が足りなくて充電できていない時は赤のようです。その辺をきちんと取説に書いてなかったので不良品と思い何度か問い合わせをしました。
