Our top pick in a charger for micro quad 1S batteries, the portable UP-S6 does it all. It provides 6 independent charging ports that can be set for regular or HV batteries at up to 1A charge rate. Each port has 3 connectors to accomodate all the commonly used micro battery types. It can be powered by a 3-4S lipo or the optional power adapter. As a bonus there's a 2.1A USB power supply built in, good for charging phones and other portable devices. The charger also features: battery reverse polarity protection, battery over voltage protection and DC input voltage protection
Optional Power Supply
With all 6 ports running at full charge levels this charger can draw just over 25 watts or ~ 2A from a 12V supply. It can be more if the USB power is in use. We opted for a 3A power supply so you've got some headroom.
