Stuffcool just launched the Numen 45 and Numen 45 Pro in India, and the headline here is not just the 45W output it is the AVS (Adaptive Voltage Scaling) support. That makes the Numen 45 India’s first AVS-compatible GaN charger, which is a bigger deal than it sounds right now. More on that in a moment.
Both chargers are priced aggressively, BIS certified, and proudly Made in India. If you have been hunting for a single compact charger that handles your iPhone, Samsung Galaxy, Google Pixel, and MacBook Air without needing a bag to carry it this lineup deserves a serious look.

What Is AVS and Why Does It Matter
AVS, or Adaptive Voltage Scaling, is Apple’s newer fast charging standard built into the USB Power Delivery 3.1 specification. It allows a charger to intelligently adjust voltage output based on what the connected iPhone actually needs at any given moment, rather than delivering a fixed voltage. The result is faster, more efficient charging with less heat generated on the device side.
Here is the catch: Apple has not yet pushed the software update that activates AVS charging on the iPhone 17 Pro series. So right now, AVS-compatible chargers like the Numen 45 are essentially future-ready hardware waiting for Apple to flip the switch. Once that update lands, compatible iPhones will charge up to 50% in just 20 minutes.
Worth knowing before you buy? Absolutely. Worth waiting for? That depends on your timeline.
Stuffcool Numen 45: Single Port, Serious Power
The Stuffcool Numen 45 is a single USB Type-C port charger delivering up to 45W PD PPS output. It is, per Stuffcool’s claim, the smallest 45W GaN charger in its category in India right now.
The physical dimensions back that claim up: 6.0 x 3.85 x 3.18 cm, weighing 110 grams. That is genuinely pocket-sized. Not “fits-in-a-jacket-pocket” pocket-sized actually fits in your jeans pocket without annoying you.
Charging Performance
- iPhone 17 Pro (AVS, post-update): 50% in 20 minutes
- iPhones and Google Pixel (45W PD): 50% in approximately 30 minutes
- Samsung Galaxy flagships: Full Super Fast Charging 2.0 support
- MacBook Air: Fully supported via 45W PD output
The PPS (Programmable Power Supply) support means the charger can dial in a precise voltage and current combination for devices that support it, going beyond standard fixed-voltage PD charging.
What’s in the Box
This is where the Numen 45 justifies its slightly higher price point. In the box, you get:
- The Numen 45 charger
- A 100W 5A Type-C to Type-C cable with an integrated e-Marker chip
That cable is not a throwaway accessory. An e-Marker chip is required for cables carrying more than 60W, and Stuffcool has included a proper 100W rated cable here. If you were going to buy a high-quality USB-C cable separately, that alone adds real value to this bundle.

Stuffcool Numen 45 Pro: Dual Port, Same Tiny Size
The Stuffcool Numen 45 Pro is the smarter buy for most people. Same compact body, same GaN technology, same AVS and Samsung Super Fast Charging 2.0 support but with two USB Type-C ports instead of one.
Both ports can deliver the full 45W individually. When you plug in two devices at the same time, the charger splits intelligently: 25W to Port 1, 20W to Port 2. That is fast enough to keep a phone and a tablet both charging at respectable speeds simultaneously, without either device crawling.
The Numen 45 Pro costs Rs 1,499, which is actually Rs 200 less than the Numen 45. The trade-off is no cable in the box. If you already have a good USB-C cable, the Pro variant is the obvious pick.
When Both Ports Are Active

Numen 45 vs Numen 45 Pro: Which One Should You Buy
This is genuinely not a difficult call.
| Feature | Numen 45 | Numen 45 Pro |
|---|---|---|
| Ports | 1x USB-C | 2x USB-C |
| Max output (single) | 45W | 45W |
| Max output (dual) | N/A | 25W + 20W |
| AVS support | Yes | Yes |
| Samsung SFC 2.0 | Yes | Yes |
| MacBook Air compatible | Yes | Yes |
| Includes cable | Yes (100W 5A) | No |
| Price | Rs 1,699 | Rs 1,499 |
Buy the Numen 45 if you need a single, self-contained kit with a premium cable included useful for travel when you want one cable and one charger sorted.
Buy the Numen 45 Pro if you already own a decent USB-C cable and want the flexibility of charging two devices without carrying two chargers.
For most buyers, the Numen 45 Pro at Rs 1,499 is the stronger everyday proposition.
Safety and Build
Both chargers carry protection against over-voltage, overheating, over-current, and short circuits. The GaN technology itself runs cooler than conventional silicon-based chargers at the same wattage, which matters over time a charger that runs hot degrades faster and puts more thermal stress on whatever is plugged into it.
BIS certification means these meet India’s Bureau of Indian Standards safety requirements for electrical products. That is not optional in India, and it is good to see both variants certified out of the box.
Stuffcool backs these with a 6-month warranty, extendable to 12 months for free through product registration on their website.
