The EBL Smart Rapid Battery Charger for Rechargeable 3.7V/3.6V Li-ion IMR Batteries are excellent for travel. This is not only because of its relatively small form factor and USB charging, but also because you only need one charger for a variety of different batteries. No need for multiple battery chargers.
Between this and the safety features such as over-current, over-discharge, over-charge, over-heating, and short-circuit protection, it’s a winner.
Because it’s a relatively small charger with safety features and fantastic flexibility, I am giving the The EBL Smart Rapid Battery Charger five stars. And don’t overlook the batteries either!
