IDMIX X45 Pro 45W GaN Charger Review: Smart Screen + Cute Emojis

Chargers are usually the most boring part of your tech setup. You plug them in, they do their job, and you forget they exist. IDMIX decided that was unacceptable — and built a charger with a personality.

The IDMIX X45 Pro is a 45W GaN fast charger with a built-in color screen that displays real-time charging information and animated emojis. It is compact, modern, and genuinely fun to use. But does the screen add real value, or is it just a gimmick? I spent time testing it with an iPhone 17 to find out.

What Is the IDMIX X45 Pro?

The X45 Pro is a single-port USB-C charger that uses Gallium Nitride (GaN) technology to deliver 45W of power in a compact form factor. GaN allows chargers to be smaller, more efficient, and generate less heat than traditional silicon-based chargers [citation:0].

What sets it apart from the hundreds of other GaN chargers on the market is the built-in color screen. This tiny display shows real-time charging data — power output in watts, charging progress, temperature — and adds a layer of personality with animated emoji faces that change depending on what the charger is doing [citation:5].

IDMIX describes it as a "desktop toy" as much as a charger — and after using it, that description makes sense [citation:5]. The X45 Pro is available in orange and white color options, adding a pop of color to your desk or travel bag.

Design & Build Quality

The X45 Pro is noticeably compact. At roughly the size of a typical 20W charger, it delivers more than double the power thanks to GaN technology. The build quality feels premium — the matte finish resists fingerprints, and the overall construction is solid with no creaking or flex.

Key design features:

• Compact footprint: Small enough to fit in any bag or pocket, making it ideal for travel [citation:0]
• 90° foldable plug: The US plug folds flat into the body, preventing scratches on other items in your bag [citation:2]
• Color options: Available in orange and white — a welcome departure from the usual black or white charger
• Fire-retardant materials: Built with PC flame-retardant materials for safety [citation:3]

The screen is located on the front face of the charger, positioned so you can see it clearly whether the charger is plugged into a wall outlet or a power strip. It is bright enough to read in daylight but not distracting in a dark room.

The Smart Screen: What It Shows and How It Works

The screen is the X45 Pro's headline feature, and it delivers more than you might expect from a charger.

The emojis are the unexpected star of the show. When you plug in a device, the charger "wakes up" with a smiling face. During fast charging, it shows a happy, energetic expression. When the device reaches 80% and switches to trickle charging, the expression becomes more relaxed. If you unplug the device, it goes back to "sleep" with a sleeping face [citation:1].

Is this necessary? No. Does it make charging more enjoyable? Surprisingly, yes. There is something genuinely satisfying about seeing your charger "react" to what it is doing. One reviewer described it as making your desk "cute" — and that is exactly the vibe [citation:5].

The screen automatically turns off after 180 seconds of inactivity to save power and reduce light pollution in a dark room.

Key Specifications

Charging Test: How Fast Does It Really Charge?

I tested the X45 Pro with an iPhone 17 Pro Max to see how it performs in real-world use. The results are solid for a 45W charger.

The screen provides real-time confirmation of what is happening. During the fast charging phase, the screen shows 42-44W and a happy face. When the battery hits 80%, the power drops to around 5-10W and the expression on the screen becomes more relaxed — exactly as IDMIX promises [citation:1].

This visibility is genuinely useful. Instead of guessing whether your device is fast charging or not, you can see it in real-time on the screen.

Heat Test: GaN Keeps Things Cool

One of the main advantages of GaN technology is lower heat generation. I measured the surface temperature of the X45 Pro during a full charging cycle from 0% to 100% on an iPhone 17 Pro Max.

The X45 Pro stays comfortably cool throughout the charging process. At no point did it become uncomfortably hot or concerning to touch. The screen also displays the internal temperature, giving you real-time visibility into the charger's thermal status.

How Does It Compare to the Competition?

The X45 Pro sits in a unique position. It is not the cheapest 45W charger, nor the most powerful. But it is the only mainstream 45W charger with a full-color display and emoji animations. If you want a charger that does more than just charge, this is the one.

Final Verdict: Who Should Buy It?

The IDMIX X45 Pro is not for everyone — but for the right person, it is a genuinely great product.

At approximately $30-40, the X45 Pro is priced competitively with other 45W GaN chargers [citation:1]. The screen adds personality and real-time visibility without a significant price premium. It is not the most powerful charger on the market, and the single USB-C port limits its utility for multi-device users. But for what it does, it does it well — and it does it with a smile.

The X45 Pro proves that even the most mundane tech accessory can be fun. If you are tired of boring black chargers and want something that adds a little joy to your daily routine, the IDMIX X45 Pro is worth a look.
