Looking for a 3in1 charger? This Dlyfull Smart Charger works good on me and i already tested it out for months and so far i dont have problem with it. I used this charger to charge my walkie talkie batteries(AA), RC car (AAA) and even the 9V rechargeable battery for my gas leak detector. This has an LCD display for observing the charging process of the batteries. For the the price i would say its a good quality charger and worth buying if you need one.
