I have a power strip with several usb-wall chargers in it. I think the only problem you'd have using a hub is simply not getting enough power to charge. What is powering the hub? If it's plugged into the wall you should be ok. If it's plugged into a computer I doubt it will do the trick. Either way I don't think trying will hurt anything; it just might not work, that's all.

I have an old USB 1.0 hub that is pretty much useless for anything having to do with computers. It has it's own power adapter so it sits on a table with gear plugged into it. Data transfer may not be all that great, but its charging capabilities are just fine. It only takes up one power slot and there's absolutely no danger of it ever frying my computer ;-)

It only has 4 ports so I've been looking for a larger version. There was a time when you could buy old, outdated, powered hubs for next to nothing but apparently they've all been scrapped - too bad, there's a new market out here.

it'll charge slowly/wont charge at all

You know how when it's not getting enough power to charge batteries will flicker or the LED will glow some weak off-color?

For some reason that reminds me of cartoons where the character gets hit with a mallet or something and their eyes go wonky and birds fly around their heads. Not sure why.

If it's a powered USB hub you could use it to charge multiple e-cig batteries. But even then you have to know what you are doing.

Say you have a powered USB hub and it runs off a 2 amp (2,000 mA) AC/DC power supply. A typical eGo battery charger dongle draws 420 mA current. So you could plug four of those eGo type chargers in: 420 mA x4 = 1680 mA current being drawn. But if you add that fifth one you are now trying to draw 2100 mA current - more than the power supply is designed to provide. Then you run into the risk of overheated power supplies and things going pop/crackle/boom/fire.

A non powered USB hub plugged into a computer? I would personally never risk charging more than one device under that circumstance. And even then, only if you can afford a damaged computer if something goes wrong. Why we aren't plugging toasters into computer USB port yet...? :facepalm:

Standard power to / from a computer USB port is 500 ma. So, very true, if the hub is not separately powered, i.e. with an adapter plugged into 120 volts, using it would be problematic at best and could fry parts of your computer.

I use a 4 port wall wart adapter, rated 2 amps, plugged into a power strip. Cost about $15, Amazon has a variety to pick from.

Conversely, if it is a powered hub, just plug it to the wall and not the computer. Since you're not transferring data into the battery, why risk damaging the expensive stuff?
