Eco USBCell: A LiPo AA USB rechargeable Battery

Posted in Technology

Even though we have already stepped into a world where we have electronics which can be recharged, still many of the electronic items are working only with AA batteries. This is where the USBCELL AA size rechargeable batteries are needed. You can simply pop off the lid to recharge by any powered USB Port on the go, in the office or at home.

Unlike most rechargeable AA and AAA cells that use nickel metal hydride chemistry, the USBcell’s are based on the same advanced lithium polymer technology that’s used in many smartphones.

That may not sound like a big deal, but one limiting factor in using LiPo in a AA or AAA battery is voltage. LiPo and Lithium Ion’s typical minimum voltage is 3.7 volts and would fry a standard device looking for 1.5 volts.

The Eco USBcell features a power control chip to match the voltage to the standard disposable alkalines we’re used to. Lithium batteries beat nickel metal batteries in recharge time and the number of times they can be recharged. And when compared to disposable alkaline batteries they have an even bigger advantage.

USBCELLs can be charged hundreds of times saving you money and helping reduce environmental waste. USBCELLs are NiMH 1.2v batteries with 1300mAh capacity. In a powered USB socket, USBCELL takes about 5 hours to charge to over 90% of capacity and partial charging also allowed. The USBCELL can help protect the environment (and save you money) by reducing the amount of waste batteries. They can also be charged in a standard approved 250 mAh re-charger.

And that’s not even the slick part of the USBcell. Once the battery is dead, you simply pull the top off to reveal a standard USB Type A port. That means there’s no need to carry a charger anymore. Plug it into a 1 amp wall-wart charger and it’ll be topped off in about two hours, even flashing an embedded green LED to let you know. The company says it can technically be charged on a computer’s USB port, but it’ll be a lot slower. Even slicker, you can attach the removable cap to the back of the battery while it’s charging, so you’re less likely to lose it.

But how can you fit a USB Type A onto a tiny AAA battery? You can’t fit a full-size one, true, but since you only need positive and negative to charge it up, the AAA Eco USBcell has half a USB Type A plug, which still lets you charge it in a standard USB Type A port.

The batteries can be recharged about 500 times before the capacity begins to diminish significantly, but in that time the company says you will have saved a lot of landfill. The list price of a pack of four is $20.
