Good product!

I left it on my motorcycle two months ago. I came back this spring, the battery is fully charged!!!!

It started making power, from the LED kitchen light.

I had never seen that before. I have held a small panel like this, under a 30,000 candle power LED flashlight, and it would not make power. The 60 watt LED kitchen bulb, made enough power to make the red light glow, on the solar panel. 7.5 watts also, I was expecting only 5. These are the good monocrystal, not the disposable polycrystal panel.

Really works!

This unit is compact and really works to keep the battery charged on my vehicle when it sits for a long time. The only problem is the suction cup feet don't work very well. But for me it doesn't matter since I just sit it on top of the windshield wiper. This is very well made and will probably last for many years. 7.5 watts per hour when the sun is out. Works on any battery.

Great Customer support!

I bought the unit in Feb,2021, and it worked great until just recently. It keep the battery at its peak, and the truck would start up quickly after sitting for weeks. Just recently I noticed the red light was on, which means it wasn't working. After fidgeting with it , I found it had a bad cigarette lighter adapter. I contacted the company, and after verification of purchase they sent out a replacement adapter. The whole problem was resolved in a matter of a few days. The charger is working great again. My experience was excellent with Powoxi, and I will make them a preferred choice for future business. All companies should be this reputable.

Good and practical, but be ware of more juice needed.

Got 7.5W, It's good for small appliances and low wattage products. It helps also with car battery maintenance, but I would prefer higher wattage after the results post trials.
