This is the UltraPower UP240AC Plus 4 Port Charger. 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 4 independant charge ports that offer up to 60Watts each if used simulatneously. What’s really neat is that Port 1 & 2 can ‘borrow’ power from Ports 3 & 4 if they are not using their full 60Watts. This gives you 2 charge ports that can max out at 12Amps/120Watts each! Very convenient for charging large batteries or for getting your packs recharged quickly before the next race. The charger can also be used as a power supply to power other devices, up to 300Watts from the DC Port at 14V! That’s Right! It acts as a DC-Out as well! 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 screen, buttons, 4mm output ports, balance port and temperature sensor 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.

High Power Output:
This charger boasts 240Watts of total charging power! Port 1 & 2 are capable of 120Watts/12Amps max and Ports 3 & 4 are capable of 60Watts/6Amps. Most chargers only allow the 240W output to be split equally between each port, 60Watts each. But what if you weren’t using the full 60Watts on Port 3 or 4 and wanted to use that extra power that’s left over to power Port 1 & 2? Now you can!
The way it works is quite simple. Each port has a dedicated 60Watts apportioned to it. But if Port 3 is not using all of its 60Watts, Port 1 can borrow whats left over! And if Port 4 is not using all of its 60Watts, Port 2 can borrow whats left over.
Here are some examples of how it works. If you are using 0Watts on Port 3, Port 1 will have all 120Watts available to it. If you are using 30Watts on Port 3, Port 1 will have up to 90Watts available. If you are using the full 60Watts on Port 3, Port 1 will have 60Watts available. The same principle applies to the relationship between Port 2 and Port 4.
Most chargers only offer 40-50Watts of charge power per channel. But this charger offers the convenience of at least 60Watts per port along with the added benefit of Port 1 & 2being able to use any extra power that port 3 & 4 is not using! Up to 120W/12Amps!

This charger offers a very small footprint so that it fits easiliy in your pit box or bag, especially for a 4 port AC/DC charger.
Charge four batteries at once, even if they are not the same chemistry, voltage, or capacity.
This charger has 4 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, GTP1306, GTP1300, GTP1340). The charger is quite compact at only 205 x 180 x 70mm (8.0 x 7 x 2.7 inches). So it can store away in your pit bag or box quite easily! The Charger also features Lithium Balance Charge, Fast Charge, Storage and Discharge modes so that you can properly care for your batteries..

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 at 14V! 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!

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.
