XTAR DRAGON VP4 Plus is specifically designed for people pursuing the ultimate lithium-ion battery charger. There are four main functions of the VP4 PLUS DRAGON: battery pack and lithium-ion battery charger, refresh/test modes, battery internal resistance test, USB output. It can intelligently distribute power when charging your 11.1V/3s battery packs, Li-ion/Ni-MH batteries and USB mobile devices simultaneously. DRAGON can also precisely test the capacity, voltage, and internal resistance of batteries. DRAGON isn't just a charger, but it's your personal battery doctor.

Compatible with almost all your batteries.
1. 3.6V/3.7V Li-ion/IMR/INR/ICR: 10440 14500 14650 16340 17335 17500 17670 18350 18490 18500 18650 22650 25500 26650 32650
2. Ni-MH/Ni-CD: AAAA AAA AA A SC C D
3. Battery Packs: 11.1V/3S battery packs
Charging your 11.1V battery pack evenly and fully.
DRAGON can charge your 11.1V/3S battery pack with 1.0A current in a balance way to make sure that all batteries of your battery pack can be fully charged. When charging the battery pack, use the supplied wall adapter.
[ 3 Optional Currents ]
0.5A/1.0A/2.0A charging currents you can choose.
Optional charging currents maximize the battery lifespan. You can charge four 32650/D size batteries at the same time.
CH1 & CH4: 0.5A/1.0A/2.0A
CH2 & CH3: 0.5A/1.0A
[ TEST Mode: Charge-Discharge-Charge ]
Accurately test the real capacity of your battery as a battery cabinet.
Comparing the discharge and charge capacities, you will know the condition of your batteries. Largest discharge capacity will mean the real capacity your battery can hold. Compared with nominal capacity, this confirms whether your battery capacity is overstated.
*Battery Cabinet: a professional instrument which can accurately test battery real capacity by the process as charge-discharge-charge.
[ Intelligent Detection ]
Personal Battery Doctor.
With a pair of probes, DRAGON can precisely measure the voltage and internal resistance of your battery just as a multi-meter does. Batteries with smaller resistance can have a bigger currents, so testing is important.
[ RECORD Function ]
Check and compare the test records of batteries whenever you want.
Built-in micro memory card will automatically save the test records of discharging and charging capacity when DRAGON finishes the process of TEST mode. The last 80 times records will be stored for your checking them at anytime.
[ REFRESH Mode: Discharge-Charge ]
Eliminate memory effect of Ni-MH batteries.
In REFRESH mode, DRAGON can maximize the capacity of Ni-MH batteries by discharging to eliminate the memory effect. It can also test the general capacity of Li-ion batteries quickly.
[ USB Output Function ]
Charge your mobile devices with suitable currents.
DRAGON with max 2.4A output current can intelligently provide suitable output currents to different external 5V USB devices. Battery used on any slot can provide power for external devices (e.g. powerbank).
[ Power-Path Management System ]
Batteries, battery pack and the external 5V USB device are being charged directly from the adapter simultaneously.
When the power is connected, external devices will be charged directly from the power instead of the batteries, so the battery could be more durable. When the power is not connected, the charger and inserted batteries will be used as an power bank to provide current for the external devices.
[ High-quality LCD Screen ]
LCD screen displays all information you want.
Battery & Battery Pack Status
Battery capacity percentage
Battery types and channels
3S Pack/USB Output status
Humanistic phonic reminder.
Remind you when the battery is reverse polarity or when the operation is finished. You can also double click to turn off this voice reminder as you wish.
Three colors of LED indicators show your batteries status.
