The GM G+ DisplayPulse 100W is a three-port GaN wall charger (two USB-C ports and one USB-A port) with a small TFT screen that shows the live wattage your device is drawing. It can supply up to 100W from a single USB-C port, enough for many USB-C laptops, but that full output drops once you plug in a second or third device. The variant linked here is the Grey model, number 75GP4X007WAEAFT.
It makes sense if you want one charger for a laptop, phone and earbuds and you like seeing what is happening while you charge. It is less convincing if you need full speed on several devices at once, or a published fast-charging standard for Samsung phones.
This explainer is based on GM Modular’s official product page, the Amazon.in listing data (captured 17 October 2026) and our explanation of what the numbers mean. We have not used this DisplayPulse 100W hands-on, and we did not find an independent review with measured results, so the figures below are the manufacturer’s and the listing’s claims.
The short verdict
- Best for: people who carry a USB-C laptop, a phone and one more gadget and want a single compact charger
- Skip if: you regularly charge two laptops at once, need a charger that confirms PPS for Samsung’s faster modes, or want the cable included
- Strengths: 100W from one USB-C port (per GM), GaN design, live wattage display, three ports, overvoltage, short-circuit and temperature protection
- Limitations: output falls sharply in some port combinations, no cable in the box per GM’s page, PPS and Quick Charge support not stated, and warranty wording differs between GM’s store and Amazon.in

How the 100W is shared between ports
The single most important thing to understand about any multi-port charger is that the big number on the box is the total, not the per-port figure when everything is plugged in. GM’s Amazon.in listing is unusually open about how the DisplayPulse divides its power, and the numbers are worth reading carefully:
| Ports in use | Output according to the listing |
|---|---|
| C1 alone or C2 alone | Up to 100W |
| C1 + C2 | C1 up to 65W, C2 up to 30W (95W combined) |
| C1 + A1 | C1 up to 65W, A1 up to 30W (95W combined) |
| C2 + A1 (C1 empty) | Both ports share just 15W |
| C1 + C2 + A1 | C1 up to 70W, C2 and A1 share 15W (85W combined) |
Two practical lessons come out of this. First, always plug your most important device into C1, which is also GM’s own advice. C1 keeps 65 to 70W in every combination, which is still plenty for a thin-and-light laptop.
Second, avoid using C2 and A1 together without C1. The listing says those two ports then share only 15W, which is slow even for a phone. If you need to charge a phone and earbuds, use C1 for the DisplayPulse 100W and either remaining port for the earbuds. The listing does not state the maximum output of the USB-A port when it is used alone.
The TFT display: what it shows and why it helps
The headline feature is the small TFT screen. According to the listing, it shows the actual wattage your device is drawing in real time, not the DisplayPulse 100W’s maximum. GM makes this point clearly, and it matters: a laptop at 90% battery might draw only a few watts, and that is normal, not a fault.
In practice, a live wattage readout is genuinely useful for three things:
- Checking your cable: if a laptop that normally charges quickly shows a low figure, a weak or 60W-rated cable may be the bottleneck
- Confirming fast charging: you can see whether your phone has negotiated a fast-charging mode or fallen back to a basic rate
- Spotting port mistakes: if output collapses after plugging in a second device, the port-sharing table above will usually explain why
The listing also describes smiley animations that change with charging status, and a long press flips the emoji so it faces you whatever the angle of the socket. The title mentions 14 animation styles. That is decoration rather than function, but some buyers will enjoy it on a desk. We cannot confirm how accurate the wattage readings are, since we have not seen independent measurements.
GaN and the compact size
GaN (gallium nitride) chargers can switch power more efficiently than traditional silicon designs, which lets manufacturers fit higher wattage into a smaller body. The Amazon.in listing gives dimensions of 7 x 2.9 x 6 cm and a weight of 65 g. GM’s product page describes it as a compact desktop or wall adapter made of high-grade plastic, and the listing mentions a hand-painted, oil-based coating meant to resist fingerprints and wear.
For travel, that means one charger can replace a separate laptop brick and phone adapter. Do check how it sits in your wall socket or extension board, because a three-port charger with a screen on top needs some clearance around it.
Phone, laptop and camera compatibility
GM lists compatibility with Android, iOS and USB-C laptops, and the Amazon.in title names tablets, MacBook Air (M4), laptops, iPhone, Samsung phones and DSLRs. Here is what that means in practice:
- MacBook Air and other USB-C laptops: a USB-C PD port supplying up to 100W has ample headroom for thin-and-light laptops. The laptop will draw only what it needs
- iPhones: recent iPhones fast-charge over USB Power Delivery, which GM states is supported
- Samsung phones: Samsung’s faster charging modes rely on PD with PPS. GM’s page and the listing do not mention PPS, so we cannot confirm those modes. The phone will still charge, but possibly at a slower standard rate
- DSLRs and mirrorless cameras: only cameras that support USB charging or USB power will benefit. Check your camera manual
- Gaming laptops: many need far more than 100W or use a barrel connector, so this charger is not a replacement for their power brick
If you only charge a phone, you do not need 100W at all. Our Samsung 15W travel adapter review explains when a basic adapter is enough and when a higher-wattage one makes sense.
Safety and protection
GM’s product page lists overvoltage protection, short-circuit protection and temperature control, and describes “multi-layer safety protection”. These are standard expectations for a charger at this wattage. As with any high-power charger, avoid covering it, keep it away from bedding and curtains, and unplug it from loose sockets that wobble or spark.
Who should buy it and who should skip it
Buy it if you want one compact charger for a USB-C laptop plus a phone, you like seeing live wattage, and you are happy to keep your main device on C1.
Skip it if you need full speed on two or three devices at the same time, if your phone depends on PPS for its fastest mode and you want that confirmed, or if you would rather buy a charger that includes a cable. Also skip it if you need more than 100W for a powerful laptop.
Other chargers to compare
- GM G+ 45W GaN Adapter (retractable cable): GM’s own store lists it as a pocket-sized 45W GaN charger with two USB-C ports and a built-in retractable cable, a simpler choice if you do not need laptop-level power
- GM G+ Adapter with LED Display, 35W: a smaller GM option with an LED charging display, QC 3.0 support, two USB-C PD ports and one USB port, according to GM’s store
- GM G+ Dual Tone 24W PD Adapter: GM’s store lists one USB-A and one USB-C port, PD 3.0, QC 3.0 and PPS support, and a 60W USB-C cable in the box, for phone-only users

Buying tips before you order
- Variant: this link is for the Grey G+ DisplayPulse 100W (ASIN B0GFDXD8ST, model 75GP4X007WAEAFT). Confirm the colour and model on the listing before ordering
- Buy the right cable: GM’s page lists only the adapter and a manual in the box. To get 100W you need a USB-C to USB-C cable rated for 100W (5A). Ordinary 3A cables are limited to 60W
- Plan your ports: keep your laptop or most important device on C1, and avoid using C2 and A1 together without C1
- Check the warranty wording: the Amazon.in listing states a 1 year manufacturing warranty, while GM’s own store page shows 7 days replacement. Keep your invoice and contact GM Modular support through the details on the listing if you need help
- Check your sockets: make sure the charger sits firmly in your wall socket or extension board

Frequently asked questions
Can the GM G+ DisplayPulse 100W charge a MacBook Air?
Yes, it should. It offers USB Power Delivery from a USB-C port rated up to 100W, which is more than a MacBook Air-class laptop needs. Use a good USB-C cable and keep the laptop on port C1 if other devices are connected.
Does it show the charger’s maximum wattage or what my device uses?
According to the listing, the display shows the live wattage your device is actually drawing, which changes as the battery fills.
Does it support Samsung Super Fast Charging?
GM’s page and the listing mention Power Delivery but not PPS, which Samsung’s faster modes rely on. Samsung phones will charge, but we cannot confirm their fastest mode is supported.
Is a cable included?
GM’s official page lists only the adapter and a user manual in the box. Plan to use your own USB-C cable, rated for 100W if you want full laptop speed.
Why does my phone charge slowly when two devices are connected?
The listing says C2 and A1 share only 15W when C1 is empty, and share 15W even when all three ports are in use. Move the phone to C1 for faster charging.
Final thoughts
The GM G+ DisplayPulse 100W combines a 100W GaN charger with a live wattage screen, which is a useful mix for anyone who wants one charger for a laptop and phone. Its weak spots are the steep drop in output on some port combinations, no cable in the box and unconfirmed PPS support. If you keep your main device on C1 and use a 100W cable, check the current price of the GM G+ DisplayPulse 100W on Amazon.in.
