Personally I think this is really cool. For $8 you provide your own batteries and you can even swap them out quickly with disposables if you need more power right away for your USB device and you don't have access to a wall outlet. twitter.com @LinusTech Buy it now at NCIX: ncix.com
This video presents an unboxing and overview of the Teratrend AA Powered Portable USB Charger from SilverStone. The host demonstrates the device by showing how it uses AA batteries, either rechargeable or disposable, to generate USB power without needing to be charged itself. The charger is designed as a compact aluminum unit with a removable bottom that reveals the battery compartment, and it uses two AA cells to power a USB output via a USB A female connector. The device is described as simple and durable, with a straightforward on/off toggle that converts batteries into portable USB power. While the stated output is a modest 500 mA, the video emphasizes the utility of having a compact power source on the go, especially when a wall outlet isn’t available. The host notes the product’s CES appearance, mentions color options including pink and green, and highlights the practical use case for travel or everyday carry. Overall, the video frames this as a highly accessible workaround for charging devices on the go, trading high output for portability, convenience, and the ability to swap in fresh AA cells as needed.
