These power banks are made from 100% recycled lithium-ion batteries, that come from old laptop battery packs.
Do your part in helping the environment and get your own Eco-Charge power bank.
To date, we have re-used over 100kg of lithium batteries.
Eco-Charge power banks are perfect for powering small Arduino and Raspberry Pi projects, as they do not have a minimum current draw required to stay on. With a majority of the commercial power banks that I have tested, if there is less than roughly 200mA of current drawn, they will turn off after a couple seconds – not the case with these batteries.
This is the fully assembled version, if you want to build your own, you can buy the kit.
More information on these power banks can be seen on the projects section here.
