Most 45W chargers are either fast or compact but getting both in the same package, at under Rs 2,000, is the more difficult part of the equation. That’s where the Stuffcool Numen 45 enters the picture. At 6.0 x 3.85 x 3.18 cm and 110 g, this is a GaN charger that delivers a solid 45W through a single USB-C port while staying small enough to drop into a jeans pocket. The headline claim, however, is not the size or the wattage, it is the protocol support. The Numen 45 is one of India’s first chargers to support Apple’s AVS or Adaptive Voltage Scaling, the fast charging standard that newer iPhones use to negotiate higher, more precise charging voltages than standard USB PD allows. Pair an AVS-compatible charger with an iPhone 17 Pro and the device charges differently from how it would on a standard 45W PD brick. Whether that difference is meaningful in daily use is a fair question, and it is one the Numen 45 gives you a reason to ask.
The charger is built from polycarbonate with a smooth matte finish and prongs that fold flat for travel. It is BIS certified and Made in India, which matters in this category where non-certified third-party chargers are both common and genuinely risky. Three colour options are available.
The size is the selling point but the weight is the noticeable. At 110 g, the Numen 45 is heavier than it looks. Some competing 33–35W GaN bricks at a similar price come in noticeably lighter. For home use this is irrelevant, but for travellers who are counting grams in a carry-on, it is worth keeping in mind before you pick it up. The plastic body will show scratches over time and a hard drop could damage the fold-flat prongs.
GaN technology does its job on thermals. During normal single-device charging the charger runs warm rather than hot. At sustained peak output, around 40–45W, the surface temperature reaches approximately 40°C. That settles back to a gentle warmth once the device crosses 80% and shifts to trickle charging. It does not become uncomfortable to touch and it does not throttle noticeably during a single charge session.
The Numen 45 supports USB PD PPS, Samsung Super Fast Charging 2.0 and Apple AVS. That covers the three most commonly encountered fast-charging devices in the Indian market: Samsung flagships, iPhones and Google Pixels.
On an iPhone 17 Pro using AVS, Stuffcool claims 50% in 20 minutes. In testing across multiple devices, real-world figures fall in the 20–35 minute range depending on starting charge level, ambient temperature and cable quality (more on that below). A non-AVS iPhone 15 or Pixel reaches 50% in approximately 30 minutes, consistent with what standard USB PD PPS delivers at this wattage. A Samsung Galaxy Z Flip, rated to 25W, charges at its maximum rated speed without issue.
The charger is also powerful enough to charge a MacBook Air, which draws up to 30W in low-demand use and benefits from a 45W input for basic productivity tasks. It will not keep up with sustained heavy workloads, but for light laptop use on the road it works just fine.
The standard Numen 45 ships with a 100W 5A USB-C to USB-C cable fitted with an E-marker chip. The E-marker identifies the cable’s capability to both the charger and the device, enabling the full 45W output. Without an E-marker cable, the charger negotiates a lower wattage; in testing with a standard 25W cable, output dropped to around 25W. The included cable is therefore is functionally required to unlock what the charger is rated for.
Build quality of the cable is fairly acceptable. The surface texture is soft and pleasant to handle, and a strain-relief spring at the connector end reduces sharp-angle bending. One of the concern is longevity because the outer material is not braided and with repeated flexing, exposure to heat or contact with moisture, the jacket may degrade faster than a braided alternative would. For desk use this is unlikely to be an issue. For frequent outdoor or travel use, replacing it with a braided E-marker cable over time would be sensible.
The Pro variant adds a second USB-C port for Rs 1,499: Rs 200 less than the standard version. The trade-off is that when a single device is connected you get the full 45W through either port. But when you connect two devices: 25W on port one, 20W on port two, that covers a phone and earbuds or two phones simultaneously.
The Pro does not include a cable. If you already own a quality USB-C cable, the Pro is the better value for anyone regularly charging two devices. If you need the cable, the standard Numen 45 at Rs 1,699 is the more complete purchase.
The Stuffcool Numen 45 makes a clear case at Rs 1,699. The AVS support is a practical differentiator for anyone using a recent iPhone and the bundled E-marker cable means the full 45W is accessible from day one without a separate accessory purchase. The compact GaN design handles heat responsibly but the six-month warranty is the shortest in the category and reflects the one area where Stuffcool should raise the standard.
For Android users on Samsung or Pixel flagships, the performance is exactly what the spec sheet suggests. For iPhone users upgrading from a standard 20W adapter, the jump in charging speed is the most tangible difference this charger delivers. At under Rs 2,000 for a 45W GaN charger with AVS and a cable in the box, the value is difficult to argue with.
