The Stuffcool Major Ultra launched in July 2024, so it’s been almost 2.3 years since it hit the market. The power bank launched at ₹3299, but it’s now ₹2699 on the company’s site, which is an excellent price.
Unboxing
The unboxing experience of the Stuffcool Major Ultra is pretty good too, since we are getting the power bank and a USB-C cable that supports 100W charging. The cool part about the cable is that it comes with PD support and an e-marker chip; it also comes with a user manual and a warranty card.

Design
The design of the Stuffcool Major Ultra feels premium while holding the power bank; it weighs around 400 grams, which is a bit on the heavier side, but the power bank doesn’t feel much heavier once you have adapted to the design. It has a metal build, and it comes with stylish graphics on the front, which look cool, though the device can get scratched up pretty easily. A quick note here: our earlier unit was a bit scratched up, but Stuffcool’s team got us a new unit, which also shows how good their warranty team is.

The powerbank comes with 4 ports, which are 2 USB-A ports on the front and a USB-C port. On the sides, you also get a micro USB charging port, which feels dated since the USB-C port on the front can also charge up the power bank. It comes with a power button, which is used to show the battery indicator, and yeah, it comes with 4 indicators, each showing how many percent your power bank has charged, which feels pretty good.



Battery and Charging
The Stuffcool Major Ultra is a 20000 mAh battery powerbank, which is good, and the size is 74 Wh, and I have tried to charge my laptop using the USB-C cable, and it can charge my Windows laptop from almost dead to 30%, and in rapid charge mode it was shown that the powerbank was trying to deliver around 25W to my laptop, and in around 30 minutes it had been at 29%, which is pretty good, and I had previously tried charging the laptop with a 65W power brick from Lenovo, and it was seen that this stuff cool was actually charging it faster than the Lenovo charger.
The Major Ultra is capable of delivering 65 W of power to the devices via the USB-C port when using compatible devices, and I used my M06 to see if it can charge in super fast charging mode, and it was consistently delivering 25W to my M06, and the device was charging it super fast too, more than my 25W charger, which was a bit of a surprise to me, and the USB-C port can do super fast charging 2.0 too on the higher-end Samsung devices and can also charge iPhones and Apple MacBook Pros at 65W.
Port, Compatibility
The USB-C port can be used to charge the powerbank too, and we tried charging the power bank from our 25W charger, and it took around 3 hours 45 minutes, which is great considering the size of the power bank. Speaking of the USB ports and their specifications, both the USB-A ports are limited to 18W of charging, and the micro USB port, which we spoke about earlier, can be used to charge the power bank at 18W, so if you have a USB-C charger, use that whenever needed instead of the micro USB.
Pricing
The Major Ultra was launched at ₹3299, but was dropped to ₹2699; the unit we have was bought for roughly 1800 with offers. For 1800, the package is quite solid; you are getting a 100W PD cable and a solid powerbank for the price, but yeah, it would be good if StuffCool actually gave us 2 USB-C ports versus 1 on the Major Ultra in their next revision. The power bank is solid at both prices, and if we do our calculations, the cable would go on sale for around 400 or 500, according to me, so the power bank is roughly 2300, which is the best deal for me.
