This, honestly, is perfect for what I need. I have my Ni-MH batteries on rotation for my Xbox controller when playing PC games. It takes a few hours to charge them fully. Each indicator is bright and reflects the current battery charging status. It needing a simple USB C charging cable is perfect. Nothing proprietary. It comes with the cable but not a charger - but we all have a one anyway so no big deal.
It's light, small, travels perfectly well. Worth the price.
