Charging to 100% is easy. Choose to use AC wall power and it takes 4.5 hours. Use solar power to get charged up in 4.8 hours. AC plus DC in just 2.3 hours. In a hurry? Get yourself powered up to 80% in a little more than half that time. Champion’s innovative design provides power on the go how, where, and when you need it.

Keep one or more extra charged-up batteries on hand to ensure uninterrupted power for your RV, van life, or camping. Extra batteries are a great idea if you want to provide backup for a few essential items in your home, or even power your pellet grill or sound system while tailgating.
