Alarmed by some reports of batteries that catch fire while charging, it just had to be a safe loader of the brand manufacturer. Due to the small charging current of 0.5A battery and charger are not warm. For the loading of course also takes a few hours, what I like to take for my intended use (occasional recharging of a protected 18650 batteries a flashlight) in purchasing. Also charging at maximum 4,25V shuts down reliably (I checked). A polarization protection and a 0V-activation (for deeply discharged batteries) are also available.
Positive in this charger are also the very small dimensions, which is why he also well suited for traveling. The power supply is ensured by Micro-USB cable. So you can charge also on mobile phone chargers and connector, Power Banks, etc. him next to the USB port on your computer.
Anyone looking for a reliable charger for a very small price, this is your place. Who needs higher charging currents, several batteries must charge the same and like to have an integrated voltage indication, must choose a more expensive model halt.
