Use The Better RE To Turn Old Smartphone Batteries Into Instant Power Banks


Like all power banks, you can use the Better RE to charge your gadgets on the go. Unlike them, you can replace the actual battery any time you want, so you can switch to a new module as soon as the one inside starts performing at sub-par efficiency rates.

A charging case designed to fit standard smartphone batteries, you can use it to put any old phone battery to good use. Whether batteries from an old phone that you’ve retired, ones you’ve decided to replace, or cheap used batteries you picked up, you can save them from being relegated to the landfill by turning them into useful tools that you can use to charge your gadgets on the go.


The Better RE is a rectangular case that can hold any size or model of smartphone batteries, with two integrated ports (one for power input, another for output). Need more power than what a single smartphone battery can carry? Not a problem, since you can buy expansion packs, a similar case (minus the ports) that can be attached (they have built-in magnets) to the Better RE for increasing power capacity. You can add as many expansion packs as you need to a single unit, although use too much and the whole thing could end up being too thick for portable use.


Dimensions are 5.1 x 2.7 x 0.5 inches (l x w x d), with a weight of 2.6 ounces. Construction is aluminum, with hardwood accents on each end.

A Kickstarter campaign is currently running for Better RE. Pledges to reserve a unit starts at $49.

    Amazing! Technology can do incredible things, and this is just one example! I love it.

    This is pretty cool, but can’t tell if you can still use the power while it’s being charged–that’s kind of unclear here.

    The idea is OK, but I’d rather opt for the USB on the go charger so you can still continue to use your phone. Also, I’m nervous about exposing the internal parts of my phone since I’m always on the go. Though, the wood-grain style here looks pretty nice. I think $50 is a little high, since the USB on the go chargers, a nice durable one, will cost you around $30 USD. And also the on the go one’s can be charged by any device via USB.
