The world of gadgets has evolved immensely and so has the need of the common man. When it comes to smartphones, the technological improvements in processors and screen displays has grown at a rapid rate. Octa-core processors and super AMOLED displays have started to catch up and though they perform excellent, all they ask for is a powerful battery. The fact that Nokia’s battery ran through a couple of days easily because the displays weren’t as bright and there was not much to play with in the phone.

Having talked about the new era of technology, what we still long for is a smartphone which can fetch you long hours via its battery. Unfortunately, the same has not happened yet and hence the rising demand of power banks aka portable chargers. A number of players have entered this sphere of power banks and the competition has started to become tough. We recently got Zoook Power Vault for ZP-PB10000L+ Power Vault for review which by the specifications looks very impressive and powerful.

Design Aesthetics

The Zoook ZP-PB10000L+ Power Vault comes in an elongated cuboidal shape with a unibody white plastic coating. The top and the bottom of the device is of blue color. It is slightly heavy to hold but you got to take it considering that it has a massive 10,000mAh capacity. The device is easy to hold in a single hand and can also fit in your denim pocket easily. The most important feature of a portable charger is how portable it is. The Zoook Power Vault lives upto it.

The top of the device has a USB slot, the charging slot and a flashlight. One side has a bright digital display and a switch to switch on/off the device or use the flashlight. The display shows the percentage of the battery remaining in the power bank, the input/output measure and a symbol indicating whether or not the flashlight is on. The front-on surface of the Zoook ZP-PB10000L+ has the Zoook branding on the top-left and the model number on the top-right.

As mentioned above, Zoook ZP-PB10000L+ has a single USB port i.e. only one device can be charged at a time. The devices supported are- mobile phones, Bluetooth headsets, smartphones/PDAs, MP3 players, portable gaming devices, digital cameras and GPS devices. Available in only white colour for now, this Zoook creation provides a good in-hand feel. It comes with a charging cable, a user manual and 1 year limited warranty.

Performance

Although the looks and packaging of the device holds importance in today’s age, it still comes down to the performance which matters the most. As the case is with a Li-ion battery, the 10000mAh Zoook Power Vault is said to have over 500 recharge cycles. You can only charge one device at a time with a maximum output of 2.1A. If you have an Android device which usually have around 2500mAh battery, you can expect to charge it from 0 to 100% 3-4 times. However, in the case of an iPhone which has a slighly lesser battery capacity, you can charge it upto 6 times using the Zoook Zp-PB10000L+ Power Vault.

Having put the device to test, I could charge a Sony Xperia Z2 two times from 0 to 100% and once from 0 to 92%. It is difficult to conclude that the capacity is exactly is 10,000mAh. But yes, it is certainly close to that as the Sony Xperia Z2 houses a powerful battery of 3200mAh. The charging output though never reached the maximum of 2.1A and remained fluctuating betweem 1.5-1.8A which too is acceptable although it took a considerable time to charge the Xperia Z2.

When it came to charging the device itself, it showed a pretty good input of around 1.5A although the manual claims it to be only 1A. The power bank itself took about six and a half hours to get completely charged. So if we consider this time at an input of 1.5A, it validates the said capacity of 10,000mAh.

Safety: It Matters

Any electronic device shows its full worth when it is highly safe for use. The Zoook ZP-PB10000L+ Power Vault provides a number of safety features packed-in. Here they are:

  • PWM Analog Control System
  • Intelligent Current-Shut Technology
  • Intelligent Control Circuits
  • Short-Circuit Protection
  • High Efficiency of conversion
