Portable Chargers

[macewank]

So, the Zaggsparq 2.0 that I have apparently won't charge the N7. Doesn't even register that it's trying to charge. LAME..


Anyone know of a good portable charger for this bad boy?

This one looks more portable than the one that came with it.
2.1 amp USB wall charger
And it provides enough amperage to actually charge the Nexus. (stock charger provides up to 2amps)

Edit: although the Zaggsparq 2.0 says it also supplies up to 2 amps, so in theory it should work, I assume you tried it in both the optimized and non-optimized ports, and with the cable that came with the Nexus.

I noticed that the N7 doesn't charge from just any charger. None of my 10W iPad chargers would work. The only charger that I found that worked happened to be an HP TouchPad charger. The TP also won't charge from anything else. So, the N7 shares the odd charger requirement with the TP. Not sure that helps...

Just tried mine. I can charge with my Samsung GNexus charger and also my old my-touch travel charger with OEM and aftermarket USB cables. Oh at my computer also. So mine works with any charger. 2amp output is optimal but still charges with 1amp chargers at a slower rate.

My Zagg Sparq 2.0 works just fine are you trying to use the incorrect port that is maded for apple products and optimized charging?

Sombody that knows more about usb charging specs will come up with the solution I am sure. In the meantime, I wonder if this would work? For only $26.07 each when QTY 50+ purchased - 12 Outlet Power Surge Protector w/ 2 Built-In USB Charger Ports - 3420Joules | Surge Protectors

Definitely curious if there is a portable battery that would work with the Nexus 7 that would not have to be plugged into the wall to charge it.

The Fuel Tank Duo charges my N7. It's available on Amazon if anybody is interested.

Have any of you tried charging with the power off? I've noticed that adapters (wall plug, not battery) that won't charge when the device is powered on will do so if it's off. Not helpful if you want to use it when it's on but if you've got no other way to charge it...

I think you nailed it. The "quick start" pamphlet says it will only charge when connected to a computer if asleep (powered off).

Stands to reason that would work with other low power sources.

I think you nailed it. The "quick start" pamphlet says it will only charge when connected to a computer if asleep (powered off).

It say "sleep mode (screen off)" which means you don't actually have to switch it fully off to charge from a computer, this is probably because the screen uses as much or nearly as much power as a regular computer USB port will provide.

Also there was a thread about charging the Nexus 7 over at XDA, where someone determined it only shows as charging when the charger is wired correctly (that is with the data pins shorted to indicate it is a dumb charger), but it will charge whenever it receives power regardless of whether it indicates it is charging or not. To do a quick test of whether it is actually charging when it doesn't say it is, you could plug the charger into a kill-a-watt type power meter and see if it uses power when the Nexus 7 is plugged in.

Just bought this https://rover.ebay.com/rover/1/711-...0556?pt=PDA_Accessories&hash=item2c673e811c4G All in One | eBay

Reasons for this: 2 amp so should support N7, charges from BOTH 110 & 12 volt so very cool, saw another seller for same item say it works with GALAXY TAB 2 7.0 so hopeful it will work with N7.

Haven't received/tested yet so buyer beware.

has anyone used one of these. it has a 2.1 amp output and 12,000 mAh just wondering if it will charge the 7 with the screen on as i use this for school.

double post sorry.

My Samsung charger and USB cable charges that N7 just fine. My Samsung car charger also works with the N7.

I got this one, pretty good deal, less than $50.

8000 mAh Portable Battery Charger | Aluratek

Not had any problems at all, it will charge my Nex7 and HTC Rezound at the same time. It has enough juice to charge both twice from 25% to full before it needs to be charged. It will take a good 8-9 hours to charge this up to full, so plan on that.

There is a youtube review that's pretty bad, but I got it anyway and it's been a charm and a lifesaver, had not one problem with it. But be careful what you try to charge with it, some devices with "suck" the juice from it (almost like shorting it out, but it isn't) and you lose your charge and have to start over for another 8-9 hours. Had it happen with a bluetooth headset with miniUSB port. So far everything with microUSB has worked.

Here's a good youtube review: Aluratek Portable 8,000 mAh Battery and Charger Unboxing - YouTube

And the bad one: Aluratek Portable 8,000 mAh Battery and Charger Review - Fail - YouTube

I got mine at TigerDirect Aluratek APB02F Portable Battery Charger - 8000 mAh, Built-in Lithium-Ion Battery, 2 USB Ports at TigerDirect.com

Oh and it shows charging from "plugged in" on the N7 and not USB charging.

This arrived and it works, both 12 volt & 110. Charging rate appears comparable to OEM Asus. Great at under $7. Sprint logo even lights up. I like it better than OEM Asus because the charger/cable are flush with the wall. Several sellers for same item.
