Along with its most popular smartphone ZenFone 2, ASUS have released a few smartphone accessories including a power bank device. Dubbed as ASUS ZenPower, the device packs a 10,050mAh battery in a miniscule form factor.
ASUS ZenPower is available in black, silver, pink, blue and gold. The black variant is priced at ₹1,599 and the silver, pink, blue and gold variants at ₹1,499.
ZenPower power bank sounds a tad expensive, but ASUS claims it is worth the price for its superior finish, fast charging and ultra compact form factor.
We received the silver variant of ZenPower for review. Let's find out how true their claim is.
Build & Design
ASUS ZenPower features a smooth aluminium exterior with rounded bezels. Measuring 90.5x59x22mm, the ultra compact form factor fits easily into one's hand and hence it is easy to carry. But the 22mm width makes the ZenPower difficult to fit in a tight trouser pocket.
Weighing 215g, the device is 5g less than OnePlus power bank, but we found the latter more ergonomic in many ways.
Talking about the build quality, ZenPower features a solid body. With the colourful exterior, ZenPower flaunts a cool look with a rugged form factor.
The power bank features an LED strip battery indicator, a power switch, an USB for output and a micro USB for charging the device. We expected at least two USB outputs, which is offered by both Huawei Honor and OnePlus power banks.
For testing the power bank, we used various smartphones and gadgets from different makers to factorise the real output. Before moving any further, we optimised the battery so that the power bank be able to offer the real life.
Out of 10,050mAh, ASUS ZenPower was expected to offer at least 8,000mAh battery back-up as around 20% battery loss is common across all available power banks in the world. And ASUS ZenPower stood true to its test. The 5.1V 2.4A output charged all the devices rapidly, but we found the charging time pretty similar to the OnePlus power bank.
Another noticeable thing about ZenPower is that it never heats up even when we used it at a stretch while charging two smartphones and an iPod Touch.
For its price, the ASUS ZenPower power bank sounds a bit expensive. But if you're are a fashion conscious consumer you can either choose from ASUS or OnePlus. Both the devices offer similar battery life, but differs in form factor and design.
ASUS ZenPower offers variety of colours with a lustrous aluminium finish, while the OnePlus comes with a similar-to-smartphone design and matte finish. Now the choice is up to you.
