 You know those mobile power banks that everyone and their dog has where you plug it in with a USB port and you charge up the battery that's built in and then you can take it around with you and you can give your devices an extra boost actually I guess we're kind of in the shade aren't we? You can give your devices an extra boost of power or just charge things on the go all that kind of thing. Great concept, love them, I have one, I use it all the time but the thing that was kind of missing for me was one that doesn't need to be charged. So what I would find happening was I would use it on a flight to somewhere, I'd forget to charge the bank itself and then on the way back I'd discover that it was dead. So this is a product from TerraTrend by Silverstone, basically by Silverstone, pen-shaped mobile charger utilizing AA batteries, so I think that's pretty self-explanatory, supports install AA battery times two, USB-A type female interface easy to carry and compact design. Now I asked for a pink one and I guess they figured I must have mistyped because they sent a green one too but the one that I actually want is the pink one. So check this out. They showed this off at CES and we actually did see it in their booth but I just want to show you guys how this works so there you go, super simple. Just like that, you unscrew the bottom, it's made of aluminum, it feels really solid, it's got a nice anodized finish on the outside so I mean it's made by Silverstone which is pretty much all you need to know so it's good. You throw a couple batteries in there, you can use rechargeables or disposable batteries, it's up to you. So there's your contact point, you go ahead and screw this back on. And then this is a quick way to turn AA batteries into USB power so now all you got to do is toggle the switch here and there's your USB charger. So it's a 500mAh charger I believe, yeah 500mAh, sorry not milliamp hour, that's a rating for the capacity. 500mAh charger so you're not going to be able to quickly charge, like speed charge a phone or charge a tablet at any sort of appreciable rate but what it is, is it's a handy little thing that you can carry around in a backpack or whatever else. It's going to be durable and you're going to be able to take an otherwise standard thing that you can buy at a store and quickly convert it into something that you can charge your device with or top up your device with. So there you go, I mean I think if you can see the application for it then you see the application for it and if you can't then you can just tell me Linus I don't see the application for it, I don't know why you made a video about this and I'll say well come on it's like a pink stick, put batteries in it, it must be good.

So yeah it's available in a variety of colors, maybe that was the point of sending me the green one. You don't have to get a pink one, so you can get green or I think there's like three other colors.
