The Tekkeon works great at 5 volts with a genuine Joye 510. Mine are rated at 2.3, lol. But dude... forget about China! I got mine here and there are plenty of places stateside that sell them...shop around: Amazon.com: Tekkeon TekCharge MP1800: Electronics

Another one that I can vouch for (vaping on it now) is this one:

I actually found this one on sale for $19.99 through buy.com ... sale isn't around anymore :(

I really like this portable battery...haven't been able to justify purchasing it though:

ZAGG | ZAGGsparq 2.0 | 4 full iPhone charges, Charges the iPad with an additional 5-6 hours of video, mobile battery, device charger, cellphone charger, portable battery pack, 6000 mAh lithium polymer battery, USB x2 at 1000 mAh output, AC 100-240 v/

6000 mAh
4 power lights (25%, 50%, 75%, 100% charge)
2 USB ports
2000mA output @ 5v
.54 pounds
Integrated wall plug

errr, ummm, that's 2A from 2 USB ports. The question is if you can get more than 1A if you're only drawing from 1 USB port? I would think so but that would be disappointing if you bought it and it didn't.

You should be able to get more than 1 amp...one port is specifically higher output than the other anyhow (optimized and general). But now that i'm looking harder, i can't find actual output from the "optimized" port. All i can find is that it is high enough to charge an iPad.

...you can charge an iPad with 0.1 amps, it just takes longer :)

Yeah, I am suffering from the same problem. Do I REALLY need a mega battery pack? Not really, but I am sure there are some who could- if they are going to be away from power for more than a day or two. But still, I have to admit the idea of just clipping a mega pack onto my belt or pants, slamming in a usb PT, and being done with it is quite tempting.

I can foresee maybe a clip on mega pack, with all the goodies included- juice, internal atty, and an internally retractable 2 foot long tube for vaping being invented. :D

Interesting since everything I read says it needs at least .5A to charge properly or it won't charge. And thats only when connected to certain computers (newer Apple machines). You try connecting it to a USB wall adapter thats rated too low and it won't charge at all. The minimum for a wall adapter it needs is 1A (iphone wall charger), and the adapter that is included with the iPad is rated for 2A (or 10W according to Apple lingo).

It was mostly a tongue-in-cheek remark :). In that you can charge a battery by reversing the current. How long it takes to charge it depends on the current. I have no idea if the ipad has circuitry to set a threshold current for charging or even how much it draws in standby or off. I think you will want a minimum of 1.8 Amps and comfortably 2 Amps for our application.

Hahah gotcha...yeah...i kinda want to get more info from Zagg now about this "optimized" port and see what the actual rating is on it. If its a higher amperage then it could be a good option. Especially with a 6000 mAh battery and an integrated wall plug =D

I'm still new around here and a little reluctant to post. But I posted earlier about the long forgotten APC UPB10. These things do put out 1.8 amps continuous and 2 amps peak. I'm using some for a 5 volt PT with very good results using KR 808 Cartos. V4L Cools work well and it burns up the cheaper ones. Had 2 around I never used until I started vaping. Then found more on Ebay for about 22.00 shipped from China. Some suppliers listed close to 1000 available. Came in about 2 weeks. Listed some places at 8 Wh and some at 10 Wh. I have 3, one old one went bad but they do put out the power to drive a PT.
