This is the UltraPower Dual Port Charger with power sharing ability on Port 1. It can borrow power from port 2, using the full power of the charger on a single channel.

It is compatible worldwide with its built in AC Voltage switch. The USA uses 110V wall outlets while other countries may use 220V. 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 2 independent charging ports. They are both capable of 120Watts and 12Amps when used together. The built in power supply provides enough power so that you can use each port at its maximum output simultaneously. The charger can also be used as a power supply to power other devices, up to 300Watts! It’s a multi-chemistry charger so it can properly charge LiPo, LiHv, LiIon, LiFe, NiMH, NiCd and Pb (lead acid) batteries. It has a built in Balancer for Lithium type batteries. Each port has its own dedicated power, screen, buttons, 4mm output ports, balance port, temperature sensor port, and PC link port. 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.

Power Sharing:
The way it works is quite simple. Each port has a dedicated 120 Watts apportioned to it. But if Port 2 is not using all of its 120Watts, Port 1 can borrow whats left over! Here are some examples of how it works. If you are using 0Watts on Port 2, Port 1 will have all 240Watts available to it. If you are using 50Watts on Port 2, Port 1 will have up to 190Watts available. If you are using the full 120Watts on Port 2, Port 1 will have 120Watts available.

Charge two batteries at once, even if they are not the same chemistry, voltage, or capacity. This charger has 2 individual charge ports and 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 sold separately). The charger is quite compact at only 180x139x60mm (7×5.5×2.4 inches). So it can store away in your pit bag or box quite easily!
The Charger also features LiPo Balance Charge, LiPo Fast Charge, LiPo Storage, and LiPo Discharge modes.

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

Power Supply:
The charger can be used to power other DC devices such as chargers, lathes, lights, etc. It puts out a whopping 300Watts of power! Simply plug the charger into the wall and use the DC port on the right side of the charger to power your device.

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!

High Power Output:
This charger boasts 240Watts of total charging power! Most chargers such as Duratrax only offer 40Watts per channel. Some may even offer 50Watts. But this charger leaves them all in the dust, allowing your packs to charge faster! It offers a high 20Amp & 12Amp charge rate.

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.
