USBCell batteries are rechargeable via USB
USBCell is a new take on rechargeable batteries – they’re recharged via USB power – just pop the top and plug them into any available standard sized USB port.
They’re not as cheap, but they’ll last a lot longer than your regular one-and-done batteries. Now while the capacity of these are not quite as good as typical rechargeables (we like Energizers), the advantage is that you don’t have to lug around a charger, and any ubiquitous USB port will do.
Get rechargeable batteries (like the USBCells) if you’re a huge battery user. Stop dumping old toxic batteries back into the system. Remember that even recycling takes energy and isn’t 100% efficient; there’s still waste.
