Are there any good, portable aftermarket chargers (or even just another stock one) I can buy for the new Nexus 7 that will allow for equivalent or faster charging as the stock charger?

I want to keep one at home and take one with me when I go to work (where I'm on the move pretty frequently and away from a regular desk most of the time).

On a similar note, if I wanted to get a car charger, do I have to get one with like a specific wattage/voltage or anything like that?

Faster is unlikely - the device itself regulates the charging speed. I've been charging my N7-2 with several different chargers & cables I already had lying around, and they've all worked great. That's the beauty of standardized charging hardware. I generally advise getting at least a 2a charger (if not 2.1a), so that it will have the ability to put out enough amperage to charge whatever you plug into it. If you're worried about compatibility, shop on someplace like Amazon & read the reviews to see if anyone else has tried it with the same device. I'll try to check some of my chargers to be extra sure, and throw some links up shortly.

*edit*

have generally had good experience with the following products. I'll try to re-edit this once I've specifically tested them with my new N7.

*Tested, confirmed working both ports* AC charger

*Tested, confirmed working both ports* Car charger

*Tested, confirmed working* Cord

I also have some chargers with a retractable cord that have been awesome for keeping in my cars, but I don't have a link handy for them. Overall, there are a gazillion options out there. The only hangup is that there seem to be 2-3 standards, and some devices work across standards better than others. I have one charger that has one USB plug marked for apple products, and the other for other products. It's not really that simple, but there is a tiny bit of hit & miss, thus my suggestion to read some reviews on amazon first, or wait for folks to point to products that have been specifically tested with the new N7.

Thanks for the help and tips! especially about the ampage. I happened to see your post right before I was about to purchase a Duracell USB car charger on the way home and ended up switching out to a different one that had 2.1a.

Gonna go check around online to see if they sell any compact USB ac adapters. I'd like something that could easier into the sleeve I keep my Nexus in.

Looks like the new N7 is very flexible about chargers - it worked with both ports of both the chargers I linked above.

Another nice thing about getting a higher amperage charger is that if it has two (or more) ports, the amperage rating tends to be total possible amperage output. So that 2.1a gets split between two devices if they're charged at the same time. Devices can (usually) charge at lower amperage than what's optimal, it just takes longer. I've had some instances where a device uses more power than the charger is giving it, and I have to shut the device off to get it to make progress in recharging.

It looks like faster charging *is* likely with specific chargers.
"you might at least be pleased to know that iFixit's teardown of the device revealed a Qualcomm PM8921 Quick Charge Battery Management IC, which allows for faster charging than conventional plugs (as long as you're using compatible adapters)." (Engadget review)

Info on quick charge:
Qualcomm? Quick Charge | Qualcomm

Yeah I've had the same experience. I've tested chargers that you buy for a couple bucks on ebay to the "official" Asus Nexus 7 charger. They all pretty much worked the same.
