The likelihood of every single one of you reading this having at least one cell phone battery you don’t use anymore buried in a box or your desk is probably pretty high. Turns out all those old batteries, in addition to obviously being bad for the environment, have about 80% efficiency left in them. With a design and size similar to a portable hard drive, BETTER RE can turn those old batteries into a reusable power pack for your current devices. The elegant slide and clip system works with batteries up to 58.5 x 97.8 x 6.5 (mm), which is the largest size currently on the market. Each BETTER RE is made with aluminum and wood and comes in four different finishes, so pick something you’re going to like for a long time because this product is usable as long as you have an old battery.
