We have both PowerWheels and Peg-Perego ATVs, so being able to get a charger with both adapters was great. Bought this right after buying quads for my kids so it makes no sense to me to compare charge times but I know the cheap wall chargers that come with toys to charge those expensive batteries so this was mine Opinion. The main motivation for buying this automatic charger. I keep both batteries on a shelf in the garage when the kids aren't driving, and I just leave the adapters plugged in, swapping between them every few days to make sure they're charged. . The indicator lights are great and it's easy to see the charge level at a glance. It may sound strange but I took an extra deep cycle marine battery on a camping trip so I can use the inverter with this charger and keep charging the quad batteries for the kids. It worked great! For convenience I can even buy another block to keep both batteries floating without swapping a block between them.
