Wow, a 120W X 2 plug-in charger. Great if you have 10,000mah battery packs, or if you want to charge your 5000mah packs at 10 Amps. And have $300.
Cool looking, fer sure.

Kinda interesting but not really worth the price. Each "side" of the charger has a 120watt output when powered by DC but only 60watts when powered by household AC current. That means on household AC it can charge a 3s 5000mah pack at a max of 5amps and the 6s 5000mah pack at a max of 2.5amps. When powered by DC current from a power supply the charge rate is limited to 7amps regardless of battery voltage or capacity.

It is convenient to have AC built in instead of running a separate power supply but I feel it's necessary to point out it's limitations. Most may never find the limits or care but some might get bit. Plus for similar money you can have a Hyperion Duo with more capabilities and 24vdc capability for charging big packs at 2c or more with ease, just need that pesky power supply.

Good point, Maj. I didn't realize those were DC-only specs. So it's really only 50W a side? Phweew! For that price, you could buy 3 of these

Nate will needle me for always recommending it, but it IS a great charger for $60. Quiet and efficient and reliable.

I have yet to see a charger with AC built in that has more than 90watt output so I'm always aware of it. For guys charging 4s 5000 or smaller packs at 1c 90 watts is fine, but for larger packs you're charging at less than 1c on AC current.

The Graupner charger does seem to have lots of features built into it though, more than I initially thought. There are also other DC only models of this charger that are 24vdc input capable and have much higher charge rates as well. I didn't look at prices but I'm sure you're going to pay for all of that stuff.

I have a Hyperion 610i (DC only model) right now running off of a Competition Electronics 13V 18amp power supply. If memory serves I'm pretty sure the 610i has 180watt output which is perfect for guys like me with 6s packs to charge at 1c. At the time it was one of the best chargers out and the best value for the features and high output it has. It's actually half of a Hyperion Duo and you can actually connect two 610i's together to operate just like Duo. The fancy stuff is nice but I don't need anything more capable than what I have.

Btw. Right before I bought the 610i I found a post by a guy wondering why his sub-100watt charger wouldn't charge his 6s brick Lipo as fast as other peoples. He set it for 5amps but it took twice as long as other chargers. A reply mentioned the sub-100wTt output of his charger and saved me from making the same mistake. Now I always look at the output wattage, divide by the fully charge voltage of the pack and that tells you the max charge rate. As an exmple the AC680 charger you linked has a max output of 80watts. So while it can charge at up to 6amps it can only do that with a 3s pack. A 4s would be 4.9 amps max and a 6s would be 3.6amps max. Nothing wrong with that but it's important for the buyer to know what the product is capable of.

Oh absolutely. Gotta know your specs. I hadn't really thought about folks who use 4S & 6S packs. Makes sense. Packs with higher voltage can be charged at higher wattages. P = I x E , Watts = Amps x Voltage. Or, E = I / P.

Are you flying helis with those "bricks"?

No flying for me. I'm just one of those guys who likes stupid power and always run 5s or 6s.

What do you run 5S and 6S in?

My daily charger is a Venom Pro Charger. Not the plus just the regular. It's this one: http://www.thebarnfloor.com/catalog/...8#.U2ZqkWdOXIU I thought they used to carry it on Tower Hobbies but I couldn't find it. It looks like they replaced the regular Pro and the Pro Plus with the Pro2 that came out. It appears that the Pro2 has a plastic shell. Why?!?!

180W must be awesome! Nice choice!

Actually Rob, I think you are recommending a great charger! But maybe not recommend the Evader so much. The Evader is definitely capable and one of the best in the 2WD stadium class. (I think the AE 2WD stadiums top it though) But there are definitely better vehicles out there for the price IMO. Just say'in.... There is probably just more hopping up to do on it than what you would have to do on a couple other ones.

I run 5s and 6s in 1/8 scale vehicles. Right now a Losi 8ight-t 2.0 and Losi LST XXL, but I've had a variety of other 1/8 buggies, truggies and MT's. As you saw by the examples in my previous posts you need higher wattage to charge higher voltage packs at 1c. Charging at less than 1c will take too long, so for me 180watts isn't awesome, its a necessity. For those running 2s-4s packs I'm sure Rob's charger is great, I've seen plenty of other people very happy with it too.

man, that thing has $250 worth of features I would never need!

Im perfectly happy with my thunder ac6. sometimes it would be nice to charge 2 lipos at the same time, but other than that it has all the features I need.

maybe if I start building planes that need 4s to fly on I would consider upgrading my charger.

Cheerz bud, I'm really happy with the end result and there is still room for more. I dare say I could run another 2 50w chargers if ever needed. But later down the track I'd like to get a 100w charger for when I get my 8ight finished

Thats an impressive output rating for a charger, and the price for that output is impressive as well.
