Review on 🌞 Topsolar 20W 12V Monocrystalline Solar Panel Kit with 10A Solar Charge Controller + Extension Cable and Battery Clips O-Ring Terminal for RV, Marine, Boat, and Off-Grid System by Johnny Chambers

Very good value for money. It can be used to charge a 20Ah battery for an amateur radio transceiver. Bought it for a field day to charge the batteries. Works great but only gets 4 stars because the instructions are absolutely sauk, the controller is a little tricky and doesn't support charging and the wire gauge between the controller and the battery is incorrect and this kit doesn't have proper fuses. I strongly recommend changing the wires. ***Update*** I used the USB port to charge an old iPad during a field day, it worked fine, but I still haven't used the USB port for anything good. The Revain Ads Q&A is a must read! The community has a de facto guide that is very helpful. TBH after doing a pretty good job with the 20w kit. I would recommend the 30W version.
