Hagibis LED Display USB C Adapter 240W 40Gbps 8K@60Hz, USB4 Connecter for Thunderbolt 4/3, iPhone 16 15 Pro Max, Current Voltage Fast Charging Monitoring Display Tester Detector

I recently tried the LED Display USB-C Adapter and was impressed by its support for Thunderbolt 4/USB 4.0 speeds. Unlike similar products, this one is particularly special! Instead of USB 2.0 500Mbps speeds, it handles data transfers up to 40Gbps meaning it can deliver a crisp 8K@60Hz output, making it perfect for high-resolution displays while showing power reportings.Build Quality & Connector DurabilityThe USB-C connector is significantly more durable than other brands I've tested. It holds up well even after frequent use, showing no signs of wear, especially on the USB C male connector piece which is typically the first breaking point of any USB connector. This sturdiness is a major plus if you often connect and disconnect devices.LED Display FunctionThe adapter features an LED display that cycles through Volts (V), Amps (A), and Wattage (W) every 5 seconds. While this offers useful insights, the cycling can be slightly distracting and overwhelming, and there's some LED bleed that makes it hard to read at certain angles. However, the readings are impressively accurate compared to similar adapters.Performance & Heat ManagementThis adapter can apparently handle up to 240W of power. However, as of 2024 to my knowledge no charging device offered to the public as a standard is able to reach such a high rating. What I have tested is charging my Meta Quest 2. At higher amperage, it gets warm but never uncomfortably hot like others have stated. Interestingly, it stays cool even with higher voltage, indicating excellent heat management.Pros:- Supports Thunderbolt 4 / USB 4.0 speeds up to 40Gbps- High power capacity (240W) with decent heat management- Durable USB-C connector, more robust than many other brands (I haven't seen any reviews from others on this item being damaged either)- Accurate power reporting for volts, amps, and wattage- Reporting goes down to decimal values, 1/10 or 0.1, rather than whole numbers, 1, 2, 3, 4...Cons:- LED display cycles every 5 seconds while updating 5 ticks of the V / A / W values, which can be slightly distracting (it shows the voltage for 5 times in 5 seconds, next the amperage for 5 times in 5 seconds, then the amperage for 5 times in 5 seconds, then recycles again)- Minor LED light bleed between readings (makes it a bit difficult to read double digit values)

Independent review. These are the best I know of and have personally tested across devices. USB4 support is crucial key. Works with new and old. I have bought these 3 times. No failures but needed more. Caution- they are really small. Easy to lose. Keep spares in the included zip lock pouch.

Solid construction and shows a variety of information. Watts, volts and amps showed on loop. Don’t have a 240watt device to test but it goes to 100watts and beyond. Pictured with my SlimQ 240watt super charger.

So this device works as intended. When you plug in a cable, it will output the wattage, volts, and amps in that order. it automatically cycles through the information. I can safely say that it works for any device below 100w. However past 100w, I cannot say that I would trust this device. I currently do not have a device that can pull more than 100w, but of the two devices that pull 100w, my power bank and gaming laptop, I would trust neither. This device gets unreasonably hot during use with both of these devices. not only that, the power doesn't seem to get past 95w when the device is plugged in. When the cable is plugged in without the meter, it works fine and the cable just gets warm. But I would imagine that someone could eventually burn their hands on this device if they would be holding onto the cable for a ~5 minute duration. Excess heat in this capacity does not give me the confidence that it will support 240w of continuous draw. even 100w seems to be the realistic limit. Since a device that uses 180w or 240w over USB C doesn't exist at the time of this review. I would say that for right now, I would say the realistic limit of 100w to 140w is possible, but I would not be the first to test it.

There’s not much to say. This is a great little tool you can use in-line to see power stats. It’s easy to use, and does give more data than a lot of adapters do. Only complaint is that sometimes it can be wonky with data connections and my iPhone.

I have tried 5 different brands of the inline power readouts. This is the only one that is readable in sunlight.Because they use proper lens tinting, it works in sunlight, and also isn't too bright indoors.A pleasant white character instead of the eerie blue/green all the others use.The gap between segments is a bit wide, which reduces readability some.This does cycle through Amps, Volts and Watts, that could be a pro or con depending on what you are looking for

I now have 3 of these. They are clear, bright, and easy to read because of the very sharp and large screen. Bidirectional metering and the screen image rotates to allow viewing from any angle.

Not built to last. Would work great if you plugged them in once and let them but they get loose quickly and won't stay inserted
