USB Rechargeable "3600mAh" Battery with USB Charging Cable for Xbox 360 Controller

Pros: The price for one is great. To buy one in my country would cost way, way more. I would recommend getting a couple! The battery power lasts long and the product is well made. Does not feel cheap by any means and you wouldn't be able to tell that this wasn't a "real" one that you would buy in stores.

Cons: There were no cons for me. I thought everything was great.

Other: Go for it, I would recommend this for sure. I am not a hardcore gamer or anything but I think this item is fantastic and very handy. For the price and quality it is worth it.

Pros: This item is great! In my country (England in the united kingdom) this would cost me atleast £15 (equivalant to about $25/$30 us dollars. This is an absoloute bargain! Works absoloutely brilliant too! The battery lasts me 20 hours easily (that's the most i've played with it without charging) but it could probably last alot more!

Cons: No cons whatsoever!! It works exceptionally well, and i get atleast 20 hours playtime from each charge! There are absoloutely no downsides to this item, what more could you ask for?

Other: Go for it buy this item! It's well worth the price! I'm about to order another two now for my other controllers! Thanks Deal Extreme!

Pros: - You can charge it while in use.
- Very cheap and holds a decent charge.
I tested the capacity of mine with a Ultrafire C3 as shown in the uploaded picture. Reed it for the full test, the test shows a capacity of 663 mAh.

Cons: - I don't know for sure but be careful with overcharging the battery with a more powerful wall charger. Hereby I don't recommend using other than USB from the 360 or PC when charging for long periods.

Other: Cheap or not cheap?
- For a battery pack it is cheap but not for the capacity of 663 mAh.
- I can get 2 Eneloop 2000 mAh batteries for $8.
