uNu Enerpak Tube 5,000mAh Backup Battery review


The Enerpak Tube by uNu features a bulit in 5,000mAh battery and flashlight. This charger is just what you need to give it an extra boost, but served with a side of practicality.

uNu’s Enerpak Tube is just the jump-start you need when your device is dead. In fact, it will provide 1-2+ extra charges to your cell phone, depending on its battery.


The Enerpak Tube is sleek and classy but note that the exterior is almost slippery. Not to worry, though, the size makes up for the silkiness.

The design was really thought through, feels great in hand, and easily fits into almost any pocket.

This battery is powered by a 5,000mAh rechargeable battery to charge your favorite electronics. This is a great item to keep in your car for a possible emergency. When depleted the Enerpak Tube charges withing a few hours.

The device is very responsive and works with a wide assortment of devices. Cell phones are charged anywhere between 1-3 additional full charges. The flashlight isn’t too bright but works well when needed in low light situations. Personally, I’d still stick with my smartphone’s flashlight, but we can knock this for having a spare.


If you need a quick go to charger for emergencies, and/or to give your phone an extra boost of battery life, this is just what you need. The uNu Enerpak Tube is available now for $59.95 in a variety of colors.
