Review on Tenergy Charger Rechargeable Batteries Detector by Melissa Paige

This is a battery charger that can charge 2 to 9 volts at a time. I use this on my dozens of machines for muscle pain, stiff joints. I operate it every day, 30 minutes for at least 5 days on a battery, if I use a regular charger without a charger, which can bring some money, it was already worth it, I bought 2 batteries, one to charge, one to use bits, buy batteries, constantly buy batteries, the charger is small but gets the job done, holds two batteries (full charge 1-2 hours.
