Smartphones have been a really mundane part of our everyday lives to the extent that a supposed 1-day battery life is starting to grow insufficient for a day’s work. Do you catch yourself sneaking in your battery charger to your office and secretly charging every break? Since the advent of Power Bank, a certain percentage of smartphone users had resolved this. Yes, only a portion. It is because not everyone is willing to pay the price for the convenience of another battery at hand. Well, these two external phone batteries can definitely whisk away your hesitation. Unu Ultrapack Go and Petalite Flux are said to have the capacity to reach its 100 percent charge in as quick as 15 minutes. So, if you happen to forget to charge your phone last night and unfortunately you woke up late the next day, charge it in for 15 mins while you are taking your shower and voila, you are ready again to face your day!

Ultrapack Go is portable with its 3.95 x 2.05 x 0.68 in (10 x 5.2 x 1.7 cm) dimensions and weighs 4.5 oz (127 g). A 100 percent of its battery capacity can store up to 3,000 mAh and requires 30 minutes of charging time. BUT charging it for 15 minutes can already supply you 2,000 mAh, which is more than enough a day use. It has a cord, which is also compatible iPhone charge cable and other cords, which you will need to connect to a smartphone or tablet via Micro USB.




The Petalite Flux is tubular in appearance, which makes it also very handy in a different way. It measures 3.54 x 1.18 x 1.18 in (90 x 30 x 30 mm) and weighs 3.35 oz (95 g). It can store up to 2600 mAh, which only need 15 minutes to reach its 100 percent. It also uses Micro USB or Apple’s Lighting connector.

Ultrapack is valued at US$60 and is already up for grabs through pre-order. Shipping is expected to start this August 25. On the other hand, Petalite’s manufacturer is planning to launch an Indiegogo campaign by end of this month and is still closed about the price details.
