eco-piggy bank / battery

eco-piggy bank

Just like you save money into a piggy-bank, store used batteries. With an USB port, it becomes possible to use the left-over energy saved in the piggy-bank. The piggy noses consist of two USB ports, which enable you to connect electronic devices to. 'Eco piggy-banks' work in a way that a gun is loaded.The trashed batteries accumulate at Eco piggy-banks and take turns in regular sequence.
You can take all the used batteries out by pushing the back of the Eco piggy-bank. USB ports have become standardized and the utilization of them are increasing.
