Keep track of all your battery-powered toys and devices with the Tethercell. This brilliant, app-connected add-on works with any device that takes AA batteries. You simply replace one of the AAs with the Tethercell, which has a AAA cell loaded inside. Once connected to the app, you'll be able to remotely turn your battery-powered stuff on and off, set device schedules and timers, get alerts when the batteries are running low, and, soon, even find Tethercell'd devices via a proximity function — so you'll never have to dig for the TV remote again.
Storing your photos, files, music, and videos in the cloud is great — but it requires an Internet connection for access, and in case you haven't heard, there's always the possibility that someone could hack your account. The Mblok solves both these problems by holding up to 256 GB of your stuff in a tiny, portable package that you can take with you anywhere. This personal cloud-like box connects to up to seven of your devices via Bluetooth 4.0, offering immediate access to your data. The battery lasts for up to 300 hours on a single charge, the app offers one-tap backups, and best of all, your data is protected with 128 bit encryption — so no one's going to see your naughty selfies, even if they steal your device.
We've seen some damn small phone chargers before, so when one claims to be "the world's smallest", we tend to be skeptical. Yet the Chargerito appears to back up its claim. This minuscule charger attaches to your keyring, and provides everything you need to power up your device, including fold-out prongs and a flip-up Apple Lightning or Micro-USB connector. As an added bonus, the design creates a sort of built-in dock for your phone, so you can still see incoming notifications on the screen from a distance — which is more than we can say for your average wall wart.
