My cousin’s pre-teen has Type 1 diabetes and has an insulin pump. Currently at home he just plugs it in while he’s in the shower and at breakfast. It’s USB powered so my guess is it doesn’t draw a TON of power. But they are gearing their 2003 Coleman Niagara for more boondocking (looking forward to the days we can go dry camping together!) She’s going to try to get me brand and info but does anyone have experience charging their pump on a 12V supply? She’s going to install a USB outlet to charge from the battery like we did. We have two 6V batteries from Costco and even with charging two iPhones daily, plus running LED lights, a little furnace and a little water pump, we can boondock 6 days with our setup. I’m just hoping I’m steering her in the right direction power wise. They also have solar panels but she’s not sure how much power they generate. It was enough to run incandescent lights and water pump for each weekly trip when her parents used the trailer years ago.
