This is the UltraPower UP100AC Plus Single Port Charger. It can be used worldwide with its auto switching power supply, compatible with 100-240V. It can also be powered by DC power, allowing it to be used out in the field when a wall outlet is not available. It has a high 100Watt Max Output! It’s a multi-chemistry charger so it can properly charge LiPo, LiIon, LiFe, NiMH, NiCd and Pb (lead acid) batteries. It has a built in Balancer for Lithium type batteries. As an added bonus, the charger has a 5V 2.1A USB port built into it to power and recharge your cell phone, tablet, etc.

LiHv Compatible:
This charger can charge the latest type of Lithium Batteries on the market, LiHv!

High Power Output:
This charger boasts 100Watts of charging power! Most chargers such as Duratrax and Traxxas only offer 40-50Watts of charge power. But this charger offers the convenience of at 100Watts, helping your batteries charge faster!

This charger plugs directly into the wall. It also can be connected to a DC power source such as a 12V car battery or a DC Power Supply (DC Power Cable not included). The charger is quite compact at only 135 x 95 x 61mm (5.3 x 3.7 x 2.4 inches). So it can store away in your pit bag or box quite easily!
The Charger also features Lithium Balance Charge, Lithium Fast Charge, Lithium Storage, and Lithium Discharge modes.

UltraPower is known for their great reliability. They use the best internal components and circuitry available to create long lasting products. Their reliability rivals that of name brand manufacturers such as Hitec, Duratrax, Traxxas, etc. And all this is backed by an easy 1 year warranty!

Lithium Battery Meter
Check the voltage of a Lithium battery’s cells when plugged into the balance port. The screen will provide a readout of each cell’s voltage, the total pack voltage, as well as the highest and lowest cells.

Battery Memory
You can program and store up to 10 different types of battery settings on each port. Then simply load the program to start charging using your stored battery settings.
