The charge current limits it to smaller capacity Lipos, or long charge times.
It would take about 2 1/2 hours to charge the majority of my 4S3300mah batteries.
Longer if the max wattage is actually all of 4W.

At $20-30 I'd be all over it, but at $50, not so much. That buys a lot of batteries and my current chargers can do everything it does, though only one at a time.

Another thought. A 4s5000 pack could charge a BUNCH of 1s150s. If it was cheaper I'd jump on it and whip up a quick series cable for a pair of 5AH 2 cell car packs and vastly cut down on what I have to take to the field. Since I can't drive, I ride a trike pulling a trailer full of UMX planes, and I just plain cannot haul a deep cycle charging battery, but I could haul a pair of 2 cells.

Hitec, I've used your products for decades, but I won't touch your chargers at their current prices, especially when they're generally YAFBCs that can be had for half of your prices elsewhere.

(YAFBC: yet another four button charger)

SFT2, 4 port Celectra will do what you need.

And you are right about, this is another re-branded SkyRC charger.

From what I could find, it won't be cheap.

No info on whether it'll bring the cells back down to storage charge either from the OP or on the Hitec website. Anyone have a clue about this aspect?

Yeah, I'm guessing that'll be just as much as the Hitec labelled charger. I'm seriously considering throwing some MCP73831 chips and digital pots on a board, along with an Arduino of some kind and a 1.8" TFT, and doing it myself for about $20.

For what it is, a fully self contained easily portable charger, that really isn't too bad. However, I really want to be able to adjust charge current, and I like working with microcontrollers, so building one sounds like fun. I'm working on talking to the TFT display now and will start figuing out how to use a switch mode power supply chip I have in my stash later. The plan is to use a large 2 cell LiFe pack to charge at least 2 single cells at a time, and have it easily scaled to more or less cells.

But that's getting way off topic. Back to the Hitec, if I weren't so cheap I'd be all over it. It looks to have a good set of features in a small package that will run on whatever power you have handy. The ability to select charge current puts it well ahead of the Celectra. I want to charge at no more than 1c before I head to the field, but once I'm there I prefer 3c so there's less down time. I routinely fly 3 planes 3-4 flights each in a 3 hour stay at the park, and I don't want to wait for batteries to charge.

I don't have any experience with the Hitec, but I picked up a "WYSIWYG 1" 4-port 1S charger a couple of months ago from 4Port.us, and love it.

http://4port.us/products/wysiwyg-1/

It's only $69 and includes an AC adapter. Pick up a $5 5V, 5A BEC and it'll do everything the Hitech can do.

Sure it doesn't have a microprocessor, knobs and fancy displays, but it is dirt simple to use and to borrow Apple's slogan, it just works. Plus, the guy that makes them really knows his stuff, and is super responsive to questions.

All you have to do is flip the current setting switch, plug in the battery and keep flying. It handles 75mA to 1100mA per battery.

I suppose the only drawback is that it doesn't speak Chinese so it will never be $20. But I have no problem paying a fair price for a quality product.

Here's a video review on YouTube.

That SkyRC charger only has 3 different socket types per charge outlet vs 4 shown on the Hitec?
