Electronic accessories brand Stuffcool recently launched its new 10000 mAh backup rechargeable battery with an MRP of 2,499 Rs. The device comes with a USB Type-C port for both the input and exit of the power supply. The spare battery comes with a range of I/O options including micro USB, USB Type-A, and USB Type C. Stuffcool backup rechargeable batteries come with support for fast charging at 3A exits using type-C ports.
Stuffcool Power bank has a capacity of 10,000mAh and uses Lithium Polymer batteries. The input on stuff cool Power bank via USB port is 5V / 2A and via USB Type-C up to 5V / 3A. This is similar to the input level for charging the device, the input through the micro USB port is 5V / 2A and through the Type-C charger up to 5V / 3A. Stuffcool Power bank has a capacity of 10,000mAh at 3.7V output and uses a 37WH battery for support.
Stuffcool Power bank comes with a plastic body with a textured matte black panel, the product itself looks not premium and offers a very simple approach. The spare battery provides a good grip in the hand and is easy to carry, the design of the Stuffcool backup rechargeable battery is very thin and sleek, fits in minimum volume, and is extremely portable. The overall size of stuff cool Power bank is much smaller than the Xiaomi Mi Power 2i 10,000mAh.
Fast charging on Stuffcool Power bank is very limited, it supports fast charging on some devices including pixel 3 which helps to bring the machine from 0 to 100 in just 1 hour 40 minutes. The spare rechargeable battery itself takes about 5 hours to fully charge with a USB Type-C cable. We tried charging the OnePlus 6t and Samsung S9+ and Stuffcool Power bank but could not quickly charge either device. Stuffcool Power bank does not support the standard 9V/2A demand for most fast-charging deployments including Samsung Adaptive Fast Charging, Qualcomm Quick Charge, spare rechargeable batteries that don’t even support OnePlus Dash Charge technology that limits Stuffcool Power bank’s capabilities for a very small range of devices.
The spare rechargeable battery comes with an LED indicator to show the battery level, the LED indicator is displayed on the opposite side of the power button and lights up when pressing the power button or USB cable connection to charge. Four LED indicators help to clearly show how much battery is left when charging the external device and how much battery remains to be charged when charging the spare battery. Speaking of connectivity, the device comes with a USB Type-C port for fast charging and has 2 regular USB ports for charging 5V / 2A. Spare batteries can be charged using a micro USB port or Type-C port.
We can get about two full charges on the Samsung Galaxy S9+ from the Stuffcool Power backup rechargeable battery, while the spare rechargeable battery is rated at a capacity of 10,000mAh, we regularly find that the test capacity is generally much less mainly due to power outages in transmission. The average conversion rate on Stuffcool Power bank is about 70%, slightly lower than the 75-80% average. The charging speed on Stuffcool Power bank is quite good, although the device does not support fast charging on the main test product, it can charge the Samsung S9+ to 100 in about 2 hours. This device does not support popular and very limited Fast Charging technologies. A backup battery charge of 0 to 100 takes about 5 hours.
Stuffcool Power bank supports cross-charging that allows you to charge connected devices and spare batteries at the same time. The power outlet stays cool for the longest time and we can only notice the heat when many devices are connected to the spare battery. The brand promises that the spare battery will last at least 500 charging and discharging cycles and provide a 6-month warranty. Stuffcool Power bank comes with a long list of safety safeguards against surges, low voltage, overpressure, overheating, and other measures.
Overall, Stuffcool Power bank is a pretty good option, however, limited fast charging options are the biggest drawback. The device has an MRP of 2,499 Rs and is usually retailed on Amazon and their own website for about Rs 1,999. This price brings together stiff competition, especially the Xiaomi Mi Power Bank 2i model that supports many faster charging options. However, Stuffcool Power bank has a very thin design and gives a good grip, making it worth buying if mobility is a top necessity.
