Physce 45W GaN Charger Review: Two Phones at Once, and a 5 W Mode for Overnight Charging

This is the English edition of a review from my Japanese YouTube channel, iestaLife. I review gadgets from my home studio in Japan, so product links go to Amazon Japan. Physce provided this charger for review (sponsored).

Quick take

The Physce 45W GaN charger is a two-port USB-C charger with a party trick: hold the button and it drops to a gentle 5 W "battery protection" mode for overnight charging. In my tests it delivered about 44 W across two phones and really did fall to 4–5 W in the slow mode.

What I tested

Physce 45W GaN charger (two USB-C ports, PD 3.2 AVS/PPS, independent power per port, RGB light, folding plug)
iPhone 17 Pro Max and Galaxy Z Fold8 charging at the same time
A USB power meter on each cable

What I found

With both phones connected, the iPhone 17 Pro Max drew about 30 W and the Galaxy Z Fold8 about 14 W — roughly 44 W in total, close to the rated 45 W.
On its own, the iPhone settled at around 32 W. I think that ceiling is the iPhone, not the charger.
A long press (1.5 s or more) turns the light green and switches to the 5 W mode. Both phones dropped to about 4–5 W, and it stayed in that mode when I unplugged one of them.
A single press turns the light off — useful on a bedside table. Many chargers have an indicator you can’t switch off.
The light cycles through colours on standby; while charging it glows reddish above 20 W and bluish below.
It weighs 107.2 g in my measurement. Compact for 45 W, but you can feel the weight.

Specs

Ports	2 × USB-C (independent power)
Max output	45 W
Standards	PD 3.2 AVS / PPS
Slow mode	5 W battery protection mode
Weight	107.2 g (measured)
Price	¥5,890 at the time of recording

Who it’s for

It suits people who charge their phone overnight in the bedroom and would rather not fast-charge every night, and anyone who wants one small charger for two phones. If you just want the cheapest 45 W charger, there are less expensive options — at ¥5,890 this is on the pricey side for its wattage.

The video is in Japanese; YouTube can show auto-generated captions. Useful chapters: 01:59 light and battery protection, 05:06 charging two phones, 06:45 measuring the 5 W mode.

Limitations

These are spot readings from a USB meter on my own phones, not a lab test, and I didn’t measure heat or long-term battery health. The price is Amazon Japan’s at the time of recording. In the video I mention that Physce sells other wattages up to around 140 W; I only tested the 45 W model.
