If you’re like a lot of phone junkies and replace your phone as soon as the latest thing comes along, you’ll know that often the hardware in the old phone is perfectly fine, even the battery. But fancier new screens and more powerful processors mean that battery life usually remains a problem, making battery packs a popular accessory. Enlighten’s Better Re lets you get some more use out of your old phone’s battery, by allowing it to slot into an adjustable external battery charger for your new phone.
Enlightened has already received awards for the design of its “upcycling power pack”, which it is now seeking to fund through Kickstarter. The idea is simple: create a case to house an old cellphone battery and create a sleek external charger. Go crazy and stack multiple expansion packs connected via magnet to provide even more charge capacity. The case adjusts to accommodate batteries of sizes up to 58.5 x 97.8 x 6.5 mm, which Enlighten says is the biggest battery currently on the market.
Enlighten argues that the average turnover of a cellphone is 1.3 years, while after two years of use, a battery is still around 80 percent efficient. Additionally, many mobile phone users who have a phone with a removable battery buy extra batteries to ensure they aren’t caught short. While reports from Recon Analytics in February 2015 suggest that mobile phone turnover rates are slowing, from 22.4 months in 2013 to an anticipated 28.4 months this year, there are still a lot of extra batteries out there.
How much charge you could get off a Better Re will of course depend on the capacity and condition of your old battery (for example, a Galaxy Note battery is 2,500 mAH), as well as what rate your current phone can charge at.
With an output of 5 V and 2 A, the company says the Better Re should charge an iPhone 6, with its 1,810 mAh battery, in just under 55 minutes, while an iPad Air 2 and its 7,340 mAh battery will take just over 220 minutes. A Galaxy S6 (2,550 mAh) and Galaxy Note 4 (3,220 mAh) should take 76 and 96 minutes, respectively.
If you don’t use phones with removable batteries such as iPhones, Samsung Galaxy models, an LG3, or a Note, Enlighten has a pledge package that includes a recycled phone battery. It also plans to produce batteries of its own.
The Kickstarter campaign offers the Better Re for a US$39 pledge, with an additional $20 for an expansion case. If everything goes to plan, delivery is estimated for November 2015.
