The Tylt Energi 2K is a very simple device combining two separate devices: a travel charger and a portable battery pack. It looks like a regular old travel charger, which converts your wall socket to a USB port, but also includes a built in battery to charge your devices on the go. But is it the travel companion you need?
Colors: Black, tangerine, lime, blue
Battery: 2,200 mAh
Where to buy: Tylt
First of all, this accessory is as simple as can be. To charge the internal battery, simply flip out the prongs on the back and plug it into the wall. You can charge your smartphone through it, as it outputs one amp of current. This isn’t sufficient for many tablets, and on the low side for large capacity devices like the Note line (which come with 2A chargers in the box), but it’s still pretty fast. During charging, it’s like any other wall adapter.
Unplug it from the wall and throw it in your bag for when you need some extra juice. When the time comes, plug your phone into the same port you used for charging from the wall. Hit the button on the front, and the indicator light will glow green to show you the phone is charging. As the internal battery dwindles, the light will glow yellow then red to indicate how much charge it has left (when pressed of course, it won’t always glow).
This simple operation, without separate ports or different modes for charging the internal battery and device, is what makes this accessory so great. You can’t forget to charge it because it’s your charger. And if your battery is dying, just plug your device in and get an extra 2,200 mAh of power. This is over two thirds of a charge for my Galaxy Note 3, and even more for other devices.
It takes about an hour to charge 20% of my Galaxy Note 3′s battery, and will fill up around 70% of the device in a little over 3 hours. It’s reasonably fast.
Of course, this device has its drawbacks. The output for charging your device is 1A for normal wall charging, which is a bit low for modern devices. While it charges pretty fast, it won’t charge as fast as some stock chargers. Also, the 2,200 mAh capacity isn’t exactly huge. In fact, it won’t fully charge most modern smartphones. To be fair, this isn’t meant to fully charge a device; it’s a combination travel charger and battery pack that’ll give you enough extra juice to get through a heavy use day.
For $40, this accessory is well worth it. Having a 2-in-1 device like this for travel is awesome, and the capacity will be more than enough for most people. Hell, it’s more than enough for an iPhone 6. If you travel a lot, this may be the charger for you.
Tylt also offers the Syncable charge and sync cable that goes well with this travel charger. With a one foot length and a flat design, it’s easily thrown into a bag and keeps the device close when topping it off. It’s not ideal to charge your device at night on your nightstand/desk, but it’s a nifty thing to have for hooking up to your computer. But at $15, it’s pricey for just a cable.
