I stopped into a Verizon store with a coworker who was buying a case for his Gnex. While there, I asked about the extended battery and got one for 50% off. During checkout, the sales associate told me about a blowout special for 7 wall chargers for the price of one, and included free shipping. So I bought that. Comes out roughly to $4 per charger, so not bad. I know there are plenty of Amazon/Ebay chargers for about that price, but when you add shipping in, they almost are always close to $10. And I've always found that those ebay chargers, even the branded ones, tend to go bad quickly.
Believe it or not, I could use 7 chargers (3 for phones, 3 for travel, 1 for work). So I sprung for the deal.
In any event, the chargers came in yesterday. They are Palm branded, LOL.
The box states for Palm Pre/Pixi. However, they are just standard plug, with USB to micro-USB cables similar to the one that comes with the Nexus. They work fine for charging, and are very high quality. I'd trust they last far longer than the crap you get elsewhere.
So for anyone looking, I'd look hard at that deal. Sell the extras if you want.
