The system is a battery charger and will charge your battery and maintain it to 13.2 V. USB chargers, at least my wireless charger is rated at one amp. USB voltage is 5 V. 5×1 is five watts per hour. So if you had two USB wireless chargers, as long as there was sufficient sunlight to charge your battery you could charge them for twice as long as the sun provided light. Anything more and your battery would start to degrade each day. **Q: can pos neg on controller power change moore dual zone frigd** A: no ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good boat battery charger *by B***E on January 7, 2026* Use to trickle charge my boat battery Works great and haven’t had any issues thus far ### ⭐⭐⭐⭐⭐ Great quality works amazing *by C***L on August 31, 2024* This solar controller with solar panel works amazing it helps me out of a tough situation when my power went out and to help cut down on my electric bill in the lighting in my bedroom.
