Overview

By popular demand we've brought back the lithium battery version of our popular Solar USB Kits!

Build your own solar powered gadget charger in minutes with this simple soldering kit! Centered around a 2200mAh Lithium Ion Battery this charger has the ability to charge up most cell phones with one full charge*. When you've depleted your battery power stick this charger in the sun or plug it into a USB power source to recharge.

You'll need some simple soldering skills to build this kit. Overall there are 15 solder points with most of them being through hole to a circuit board. Build time is is between 20-45 minutes and will require a soldering iron and screw driver, though it isn't a bad idea to also have a wire cutter/ stripper around.

Lithium batteries are a very common power source and can be found in nearly every smart gadget around your home. However they can also be quite dangerous if they're not handled properly. We do not recommend anyone under the age of 14 to build this project without direct adult supervision and appropriate safety gear. When in doubt, try one of our other Solar USB kits that use AA batteries.

*Different phones, gadgets, and tablets have wildly different sized batteries inside which makes it difficult to judge just how much this charger will actually charge up your device. In general when it's 100% charged up it should charge up most cell phones between 75-100%. We don't recommend charging up tablets.

Soft and washes well.
Size: 30" X 20", Color: Grey
These are great rugs and I keep going back and buying more. They are such a good value for money and they wash really easily. They don't slide or shed and they are very durable. They are very soft.So far we have them in both bathrooms and next to our bed.

Great Purchase
Size: 24" X 24" Contour Rug, Color: Beige
I picked these rugs (I purchased 3 of them) because it said its for elongated toilets. I have elongated toilets so I ordered for each room, they are a little large. I thought they would fit the toilet perfectly and not be large where it moves away from the side of the toilet. they are all very soft, like a shag rug, nice and thick and they come in many colors. The only thing I would change is the price of the light grey rug.

Good mat, good price, 'nuff said.
Size: 30" X 20", Color: Grey
While the photo suggests that this mat is enormous, it is a pretty good size at 30 x 20 inches. The chenille is very soft and feels nice on your feet. There is a rubber backing that prevents slippage on smooth bathroom floors. Overall there is nothing terribly noteworthy about this bathmat - it's a nice, high quality mat at a very good price. A good deal every day.
