This product has been replaced by the EV-Peak CQ3 Charger.

This is the EV-Peak 400Watt Four Port Quad Charger. It can be used with 110V/120V outlets and 220V/240V outlets. The USA & Canada use 120V wall outlets while other countries may use 220-240V wall outlets.
The charger DOES come with a selectable voltage switch, allowing for worldwide compatibility.

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. The Charger also features LiPo Balance Charge, LiPo Storage, and LiPo Discharge modes.

High Power:
The Q6400AC can output up to 100Watts/10Amps from each port at the same time! Each port is fully independent of each other and has its own dedicated power! Using 100Watts/10Amps on a port in no way limits any of the other ports’ ability to charge to its full potential! Max the charger out by using 100Watts/10Amps on each port at the same time for a total of 400Watts!

EV-Peak 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 100Watts of power per port! Most chargers such as Hitec only offer 50Watts per channel. But this charger leaves them all in the dust, allowing your packs to charge faster! It offers a 10Amp charge rate!

Digital Power Mode
Each Port can act as a power supply! Use this function to power external items such as a pit light, tire truer, motor checker, charger, or anything else that runs off of DC power. Both the Voltage and Amperage are adjustable to suit the needs of the connected device.

Lithium Cell Check
Check the voltage of a Lithium battery’s cells when plugged into the balance port. Simply hold the INC button when in a Lithium menu. The screen will provide a readout of each cell’s voltage.

Adjustable Cutoff Voltage
The voltage per cell at which the charger stops charging the battery can be adjusted for fine user precision. Adjustments available for LiPo, LiIo, LiFe, Pb batteries.

  1. Valentino Wernet

    This item is good. It’s my favorite charger out of all the ones I’ve ever owned. Thank you.

  2. Alex Valler

    I purchased four of these units. They work exactly as described. The instructions are pretty easy to understand. Their only weak point is the cooling fan. On one out of four units it started making a noise after two days of use. Dirt Cheap RC is sent me a new fan right away, and that fixed the problem. I use these units a lot, and they work very well. They have a great value for your money.

    I have only used this charger a few times, but what I have used shows that it rocks! It works so much better than my old Hitec charger, and it comes with all the bells and whistles you’ll ever need. I received fast shipping, and a company that stands behind their product. What more could you ask for? Thanks guys for an awesome charger!
