Double AA Rechargeable USB Battery – 4 Pack
These are 1450mAh batteries that are rechargeable via standard USB port.
This is the better way digital devices should be designed. I am not a fan of, for example, my portable speaker going south because the device can no longer hold a charge. I’d much rather have my portable speaker take batteries which I can replace, than my device going dead and I have to throw it away.
As I type this, the four pack of double AA batteries are going for $35. So just under $10 per battery.
The company claims they will take 500 charges. Assuming they have over stated that statistic, even at 250 charges… it’s a smart move.
They also claim the AA battery will last 2 to 3 times longer than a normal battery. Probably a direct link to the 1.2V NiMH nickel metal hydride cell technology.
So what do you get for $35? Four Double AA batteries, carrying case and a 4 port USB hub with individual power switches and LED lights for power status feedback.
One final note, the size of the battery makes it so any USB port will accommodate the battery. In a car charging part, your thin laptop or socket off a PCI card.
Amazon customers have given this a 4.5 star rating, with a total of 159 reviews. Clearly no buy remorse here.
