“I bought the ECO-WORTHY Solar Car Battery to keep my car battery topped off while I’m away for several weeks at a time. The battery arrived in decent packaging. Installing it was straightforward, and it seemed to be working fine at first. I’ve noticed that the pre-start voltage readings have stayed pretty consistent, although not as high as I hoped for.

It’s at 18-12.0V every time I return. It’s useful but not quite what I expected in terms of boosting the battery. Still, it helps me avoid a totally dead battery.”

“I ordered the ECO-WORTHY Solar Car Battery to maintain my car’s battery when not in use. When the package arrived, it was partially open and components were missing. Amazon did a great job processing the replacement quickly, but the new package came with instructions in a foreign language. Some trial and error were required to figure it out.

The battery does work, although I can’t tell if it’s at full efficiency. Overall, somewhat useful but the initial setup was frustrating.”

“I used the ECO-WORTHY Solar Car Battery while I was deployed for a year, and it works reasonably well. I set it up inside the windshield with the provided suction cups. Over time, it did prevent my car battery from dying completely, although the battery was not fully charged when I got back.

Also, there were moments when it didn’t seem to charge effectively. For the price, it’s good enough for maintaining the charge rather than fully replenishing it.”

“This solar battery charger was a bit of a mixed bag for me. The installation process was simple enough, but the instructions were not in English so I had to look up a PDF online. Initially, the battery seemed to top off well, but after a few weeks, my car struggled to start.

It’s an OK product; it just didn’t perform as well as I hoped.”

“Bought the ECO-WORTHY solar battery for my motorcycle and car. Works decently for short-term maintenance of battery charge. Good for someone who doesn’t use their vehicles daily. The solar panel is compact and light, fitting well on my dashboard.

However, the charging rate is slower than I’d like, but for trickle charging, it does the job.”

“When traveling, the ECO-WORTHY Solar Car Battery was a handy solution. It’s lightweight and easy to set up. However, during testing, I didn’t see a significant improvement in battery voltage.

It’s useful to avoid a completely dead battery, but don’t expect it to fully recharge a depleted one. Decent for maintaining battery life during short absences.”

“I use the ECO-WORTHY Solar Car Battery maintainer for my spare car. The battery stays above 18V which is enough to start the car occasionally. Handy since my car is parked for long periods. Suction cups lost their stickiness after a month or so.

It’s useful but could use better mounting options.”

“The product was delivered quickly and in good packaging. Setup was relatively easy, but the battery maintains the charge instead of significantly boosting it. I measured consistent voltage but never higher than what it started with.

It works for keeping the battery alive, which is better than nothing.”

“I purchased this solar battery maintainer for my seasonal car that stays parked for months. The ECO-WORTHY Solar Car Battery has done a decent job maintaining the battery’s charge but nothing extraordinary. The pre-start voltage is usually just enough to turn over the engine, but it’s a good value for the price.”

“Received the solar battery pack and started using it for my old sedan. The initial setup was straightforward, but I had to translate the German instructions online. So far, it keeps my battery from dying completely but doesn’t seem to fully charge it.

It’s useful as a maintenance tool and does help a bit, but I'd consider other options in the future.”

“This product helps avoid a dead battery when my car is not in use for weeks. Solar panel design fits well on the dashboard. It maintained the battery voltage reasonably but didn’t fully charge it.

Installation was hassle-free except for the instructions not being in English. Overall, it’s useful but not perfect.”

“I’ve got mixed feelings about the ECO-WORTHY Solar Car Battery. It works well in terms of not completely letting my car battery die out when I’m on leave. However, my car’s starting voltage remains low. Simple to set up and use, but performance is average at best.

Good enough for minor maintenance.”

“Quality-wise, the ECO-WORTHY solar battery is decent. Installed on my windshield with suction cups, and it seems to slightly maintain my battery’s charge. Instruction manual was complicated due to language issues.

For the price, it does offer value but don’t expect significant charging capabilities. Does okay in maintaining function.”

“This ECO-WORTHY Solar Car Battery comes in handy for maintaining batteries of my back-up vehicles. Keeps voltage from dropping too low when I’m not using the car. The setup was also more straightforward after finding an online manual in English.

Doesn’t fully charge, mainly useful for battery maintenance rather than extensive charging.”

“Using this battery maintainer on my car for over six months now. It’s fair in terms of keeping the battery alive for short periods. Voltage measurements are stable but barely over the threshold to start the car.

Also, setup instructions were unclear as they came in a different language. It’s a convenient solution but has its limitations.”
