Stuffcool is India’s main charging model, and I coated a number of of their merchandise up to now. The Main Max is a 20000mAh energy financial institution that is ideally suited in case you have a Samsung cellphone, and Stuffcool is rolling out a brand new mannequin dubbed the Main Extremely, going as much as 65W.
Clearly, the massive differentiator is that the ability financial institution now delivers 65W of energy over the USB PD 3.0 protocol. After all, that comes with the inevitable worth hike, with the Main Extremely retailing at ₹3,299 ($39) on Amazon India — the Main Max nonetheless prices ₹2,299 ($27) . I believe the Main Extremely is by far the higher alternative contemplating you get 65W charging as normal.

Because the Main Extremely is a brand new variant of the Max, the design is equivalent. The facility financial institution has a silver aesthetic that appears a bit cleaner than the essential design of the Main Max, however there’s a number of obtrusive textual content and branding on the system that does not cater to my tastes.

The Main Extremely has an oblong design, and also you get the identical LED indicators that spotlight remaining battery degree. There is a energy button on the correct, and a Micro-USB port on the left; just like the Main Max, you need to use the Micro-USB port to cost the ability financial institution at as much as 18W. I do not get the utility of the Micro-USB port; if you happen to’re like me, you’ll’ve converted to USB-C by now, and it is unlikely {that a} majority of Stuffcool’s supposed userbase would have Micro-USB cables mendacity round.

Whereas I haven’t got any points with the design itself, the construct high quality is not fairly on par with different energy banks. The Main Extremely had one tumble within the month I used it, and the ability button dislodged; it is titled to the facet, and is unable to be activated. This is not a giant deal as the ability button would not do a lot aside from point out remaining battery degree, but it surely’s nonetheless annoying.

The Main Extremely comes with one USB-C port and two USB-A ports. The USB-C port is the one which goes as much as 65W over the PD protocol, with the USB-A ports restricted to 18W. Stuffcool clearly reused the identical design because the Main Max, so it went with the identical port configuration, however the model ought to have supplied two USB-C ports — all different 20000mAh energy banks I examined within the final 15 months have a minimum of two USB-C ports, and the Extremely is distinctly on the backfoot in consequence.

The solitary USB-C port limits the flexibility of the Main Extremely, however the energy financial institution has a novel benefit in that it hits 65W over the USB PD PPS normal, making it a improbable alternative to be used with Samsung gadgets. Sure, you get only a single USB-C port, but it surely delivers a dependable cost, and the power to make use of it with Samsung gadgets is a giant deal on this class.

What’s additionally nice is that the inner battery prices at 65W; it takes simply over three hours to cost the 20000mAh battery, however it’s significantly better than the Main Max. The Main Extremely makes use of normal USB PD 3.0 energy profiles, and here is a fast rundown:
USB-C in/out (65W Max): 5V/3A (15W), 9V/3A (27W), 15V/3A (45W), 20V/3.21A (65W)USB-C PPS (65W Max): 3.3 – 13.5V/5A (65W)USB-A1/A2 out (18W Max): 5V/3A (15W), 9V/2A (18W), 12V/1.25A (18W)Micro-USB in (18W Max): 5V/3A (15W), 9V/2A (18W)
With two gadgets linked to the ability financial institution, the USB-C port goes right down to 45W, with both USB-A port restricted to 15W, going as much as a most of 65W. I used the Main Extremely over the course of a month to cost the likes of the Pixel 9 Professional XL , Vivo X100 Extremely, Xiaomi 14 Extremely , and a bunch of different gadgets, and I did not see any issues with charging. The twin USB-A ports are higher suited to cost equipment, and that is what I ended up utilizing more often than not.

Stuffcool additionally did a fantastic job with the bundled cable this time round. It goes as much as 100W and delivers 20V at 5A with out breaking a sweat, and I used to be ready to make use of it to cost notebooks and different gadgets with ease.
General, the Main Extremely is an honest improve over the Main Max, and it would not price an excessive amount of extra. It continues to be one of the reasonably priced selections if you happen to want a 20000mAh energy financial institution with 65W PD charging, and the power to maximise the charging potential of Samsung telephones is an added bonus.
