Kendra’s new soccer chair really sucks down the juice! I put in some premium new batteries, but after two games and a day of running around, they were all the way down to empty. For Team USA, we are looking at getting a second set of batteries to carry with us, but that’s heavy and expensive.
This made me think- why not just charge them 3x as fast? These chargers would do the trick:

They each weigh about 5 pounds, fit in a backpack, and cost less than a pair of batteries. When everyone else has been charging for an hour during lunch, it will be like she charged for 3 hours! Caution to anyone else trying this, though- you need to rewire things to keep from breaking anything.
