Review on 🔋 Lasica 18V 3.0A Fast Battery Charger PCXMVC Replacement for Porter-Cable 18-Volt Battery Packs - Efficient Charging for NiCad, NiMh & Lithium-Ion Cordless Tools PC18BL PC18BLEX PCMVC PCC489N by Sam Hansen

Batteries charge very quickly as described, typically in 1 hour or less. However, they also discharge quickly because they are not charged to the correct voltage. Recharged batteries will NOT work in computer mice, clocks, etc - those items that require the exact 1.5 volts that a new battery provides. No matter how hard you charge them, they don't reach 1.5 volts. In any case, the device turns off after charging. They break easily. They are mainly used for Xbox and PS4 controllers and kids return them a few hours after borrowing them. Not what I expected. Disappointed with the quality of the charge.
