This battery is perhaps the best portable battery I've bought so I'm gonna do my best convince you to buy it. It's also discontinued, so it could sell out any time.For $22, this battery is on par with those fancy expensive external battery packs sold in Best Buy and other accessories. It's well made and light, has a simple button with different lights representing battery usage, and can charge the to nearly full battery around 2 times, but this is just going off of the mAh rating.You need to charge it the same way to do a Vita, but once it's fully charged, all you need is the USB cable for the Vita and you're good to go. You can then slip it into your pocket or preferred case of choice (the official Vita pouch works great for this, since it has two accessory pockets) and you're not gonna run out of juice while out for a long period of time.Did I mention it can charge other portable devices, too? All you need is the USB cable for that device and you're golden. Of course, it's not gonna fuel up higher batteries like an iPad or MacBook, but for things like smartphones, you can get multiple charges out of this thing.Overall, this is a great purchase for not just my Vita, but my other portable devices as well, and I'm glad I managed to pick one up after it's discontinuation.
