Review on ⚡️ Efficient POWOXI 1.8W 12V Portable Solar Car Battery Charger: Ideal for Automotive, Motorcycle, Boat, ATV, RV, and More! by George Jacobson

Not suitable for charging a 12V car battery. I couldn't even get it to light up a simple 12 volt car lightbulb. I left the charger on the car battery that was used for my caravan for more than a week. The battery was charged as I had just disconnected it from the house and the fridge and lights in the camper were working fine. I unplugged my camper from home and plugged in this charger to see if it would hold a charge. The blue light is off. I plugged in the reverse connector and the light came on, not blinking. Didn't charge or hold a charge. The battery was empty after 8 days. I took the battery from one of my everyday cars and plugged it into the camper without using the reverse connector so the blue light was off when plugged in. Again the battery didn't hold a charge. There were no instructions or description for the video. Tried running a 921 bulb with it. Unsuccessful. Already threw away all the packaging. Will contact support and update later.
