    For the price this is seriously a steal!! Very easy to use, protects from short circuiting, charges 2 very quickly and 4 at a time seem to take no time at all!

    Perfect Charger

    Posted by Brandon Kroening on Jun 2nd 2016

    This charger is perfect. 3 different charging options and the LED readout is the nicest luxury. Never going back to the 2 bay SODA charger now.

    This is the perfect charger! I can charge my batteries and my phone at the same time. Not only does it charge them perfectly but it takes the guessing out of how long until they are fully charged. LED readout is a perfect addition to this charger.
