Review on ⚡ Fast-Charging Multi-Voltage Battery Charger for Milwaukee M12 & M18 - Charges Compact Batteries in 30 Minutes and Extended Capacity Batteries in 60 Minutes - Power Tool by Shawn Hodges

Works great! I chose this model because it clearly says "Milwaukee" and I had no reason to doubt its authenticity. Didn't know what to expect (read it's a slightly older model or was expecting something refurbished) but looked brand new and works great! Charges my M18 5.0 in about an hour or less! And less than half the price my local hardware store is asking! If for some reason you need a charger (I got a 'free' battery with the power tool but no charger) it's definitely worth it!
