overcharge protection,
overcurrent protection,
over temperature protection,
short circuit protection,
reverse connection protection,
over discharge protection



The DC adapter easily folds out to charge and pack away.
Smart charger can charge one and two at a time.
Trickle current / constant current / constant voltage three-stage charging, the maximum charging current can reach 1A
reverse-polarity/ fireproof shell / perfect heat/ dissipation
Intelligent temperature control technology, the charging current will decrease with the rise of temperature, the output of the
maximum charging current under the premise of no overheating protection
Makes the USB Plus the safest charger and ensures your safety.
Cut off the voltage at 4.20V / CC-CV charging method / Soft start / Bat-vdd voltage anti – reverse function .
Avoids sudden high current impact and maximizes batteries’ lifespan.
Fast charge with 1A max current / 0V activation function / Standby current less than 1uA .
Fulfills emergent use with 3 hours charging time.
Besides, the battery rescue function maximizes batteries’ lifespan.
These user-friendly designs give convenience especially for traveling.
