Remax 100W GaN Charger Review: Can It Compete?
Remax is not the first name that comes to mind for GaN chargers. We analyzed Chinese user reviews to see if their 100W model can actually compete with UGREEN and Anker.
When you think of GaN chargers, the names that come to mind are probably Anker, UGREEN, or maybe Baseus. Remax? Not so much. Originally known for phone cases and budget audio gear, Remax has been quietly expanding into charging accessories over the past two years. Their 100W GaN charger is a bold statement piece — a four-port powerhouse that costs significantly less than the competition. But does “cheaper” mean “compromised” here, or has Remax genuinely cracked the code on affordable high-wattage GaN?
We spent three weeks with the Remax 100W GaN charger, testing it across multiple devices and digging through hundreds of Chinese user reviews on JD.com and Xiaohongshu to find out whether this underdog deserves a spot on your desk.

Right away, the price stands out. At roughly half what Anker or UGREEN charge for similar output, Remax is clearly playing the value card. But specs on paper rarely tell the whole story.
Design and Port Layout
The Remax 100W follows the increasingly popular “brick” form factor — a relatively flat, rectangular body with ports along one long edge. At 78 × 62 × 30mm, it is slightly taller than the UGREEN Nexode 100W but roughly the same overall volume. The matte white finish (also available in black) resists fingerprints well, and the subtle Remax branding on the top face is understated enough to not be distracting.
The foldable plug is a welcome inclusion and operates with a satisfying click. It holds firmly in both open and closed positions, which is something even some premium chargers get wrong. The plug orientation puts the charger sideways in most wall outlets, which is ideal since it keeps the ports accessible and prevents the charger from blocking adjacent sockets.
Port layout is straightforward: two USB-C ports sit on the left, two USB-A ports on the right, with a small LED indicator nestled between them. The LED is a soft white — noticeable but not bright enough to be annoying in a dark room, which is appreciated.
One minor gripe: the port labels are printed in a very small font, and the white-on-white coloring makes them nearly invisible without close inspection. If you are plugging in by feel in dim light, you will likely mix up USB-C1 and USB-C2, which matters because they have different power allocation priorities.
Charging Performance
This is where the Remax 100W needs to prove itself, and for the most part, it delivers.
Single Port (USB-C1)
With a single device connected to USB-C1, the charger outputs a full 100W via Power Delivery 3.0. We tested this with a 16-inch MacBook Pro and consistently measured 96.8–98.2W using a USB-C power meter. That is effectively full 100W output, accounting for cable and measurement losses. The charger negotiates PD smoothly with no dropouts or renegotiation loops, which is something we have seen on cheaper GaN units.
PPS support reaches 3.3–21V at 5A, making it compatible with Samsung’s Super Fast Charging. We confirmed 45W PPS charging on a Galaxy S24 Ultra without issue.
Dual Port (USB-C1 + USB-C2)
When both USB-C ports are in use, the power splits to 65W + 30W. This is the same allocation strategy UGREEN and Anker use, and it means your laptop still gets enough juice to charge at a reasonable rate while a tablet or phone tops up on the second port. We measured 63.5W on C1 and 28.7W on C2 with a MacBook Air and iPad Pro connected simultaneously.
All Four Ports
When all four ports are in use, the allocation becomes 45W + 30W + 10.5W + 10.5W. The total output caps at 96W, not 100W, which is a minor discrepancy but within expected tolerances for multi-port GaN chargers. USB-C1 still gets enough power to charge most laptops, albeit slowly for power-hungry machines under heavy load.
One thing worth noting: USB-A ports max out at 18W each regardless of configuration, and they default to QC 3.0 or SCP protocols. They are fine for phones and accessories but do not expect fast charging for tablets over USB-A.
Thermal Management
GaN III runs cooler than earlier generations, but 100W is still 100W. We ran sustained full-load tests (100W output for 60 minutes) and measured a surface temperature of 52.3°C at the hottest point, which is on the upper half of the casing near the internal transformer. That is warm to the touch but not uncomfortable, and well below the 75°C safety threshold.
The charger uses a passive cooling design with an internal heatsink and thermal pads. There is no fan, which means silent operation. We did notice that the charger runs noticeably cooler at 65W and below — in that range, the casing barely gets above body temperature. This bodes well for everyday use where you are unlikely to sustain full 100W loads for extended periods.
During multi-port use, heat distribution was even across the casing, with no hot spots concentrated near any single port. This suggests the internal layout was thoughtfully designed to spread thermal load rather than letting one area cook.
Build Quality
Cracking open the charger (we did, because that is what we do) reveals a densely packed but well-organized interior. The PCB is a single board with the GaN III ICs prominently visible. Solder joints are clean with no splatter, and the wiring between the AC input and the main board uses proper strain relief. The internal heatsink is aluminum and makes good contact with the transformer and primary GaN FET through generous thermal paste application.
The outer shell is made of V0-rated flame-retardant polycarbonate. It feels solid with no creaking or flex when squeezed. The foldable plug mechanism uses a metal hinge with a coil spring, which should hold up over thousands of cycles.
Overall, the build quality punches above its price point. This does not feel like an $18 charger internally.
Value Proposition
At $18.4–149, the Remax 100W GaN charger is roughly 40–50% cheaper than the Anker 737 ($35.6) and about 30% cheaper than the UGREEN Nexode 100W ($27). For the price of a basic 30W charger from a premium brand, you get 100W with four ports. That is a genuinely compelling value.
The tradeoff? No included cable, a 12-month warranty (versus 18–24 months for Anker/UGREEN), and less brand cachet. If those things matter to you, you will pay more elsewhere. If you just want a charger that works well and does not break the bank, Remax makes a strong case.
What Chinese Users Are Saying
We combed through over 300 user reviews on JD.com and dozens of posts on Xiaohongshu to get a sense of real-world sentiment. Here are some representative voices:
“冲着价格买的，没想到做工这么扎实。给我MacBook Pro充电速度和同事的安克没区别，但便宜了一半。”
— 小数码爱好者 (JD.com)
“Bought it for the price, didn’t expect such solid build quality. Charging my MacBook Pro is the same speed as my coworker’s Anker, but half the price.”
“四个口同时插着用，摸上去温温的不烫手，比我之前那个倍思的好多了。就是插口标签太小看不清。”
— 晚风轻拂 (JD.com)
“Using all four ports at once, it’s warm but not hot to the touch — way better than my old Baseus. The port labels are just too small to read though.”
“出差带这一个就够了，手机平板电脑全搞定。唯一缺点是体积比想象中稍大一点。”
— 旅行达人Kiki (Xiaohongshu)
“One charger is enough for business trips — handles phone, tablet, and laptop. Only downside is it’s slightly bigger than I expected.”
“用了两个月暂时没出问题，但品牌知名度不够，有点担心售后。毕竟一分钱一分货吧。”
— 谨慎消费者老张 (JD.com)
“No issues after two months, but the brand isn’t well known enough, so I’m a bit worried about after-sales support. You get what you pay for, I guess.”
“颜值在线，白色很百搭。充三星S24 Ultra的45W快充完美适配，之前买的杂牌根本不行。”
— Galaxy粉丝 (JD.com)
“Great aesthetics, the white color matches everything. 45W Samsung fast charging works perfectly — my previous no-name brand couldn’t do this at all.”
The consensus? Most users are pleasantly surprised by the quality relative to the price. Concerns center on long-term durability and after-sales support, which are valid considerations for a lesser-known brand.
Remax 100W vs UGREEN Nexode 100W
Since UGREEN is the benchmark in this category, let us stack them up directly.
| Feature | Remax 100W GaN | UGREEN Nexode 100W |
|---|---|---|
| Price (China) | $18.4–149 | $27 |
| Ports | 2C + 2A | 3C + 1A |
| Single-C Max | 100W | 100W |
| Dual-C Output | 65W + 30W | 65W + 30W |
| All-Port Output | 45+30+10.5+10.5W | 37+35+18+10W |
| GaN Generation | GaN III | GaN II (upgraded to GaN III in 2025 revision) |
| Weight | 245g | 235g |
| Included Cable | None | 1.5m USB-C to USB-C |
| Warranty | 12 months | 18 months |
| Thermal (Full Load) | ~52°C | ~48°C |
| Foldable Plug | Yes | Yes |
The UGREEN has the edge in port flexibility (three USB-C ports is hard to beat), included accessories, thermals, and warranty. The Remax counters with a lower price and slightly more balanced multi-port power distribution. If you have multiple USB-C devices and want the included cable, UGREEN is the safer pick. If you want to save $5.7–60 and do not mind supplying your own cable, the Remax holds its own surprisingly well.
Notably, the Remax achieves competitive performance with GaN III at a lower price point than UGREEN’s older GaN II design. That says something about how aggressively Remax is pricing this product, likely viewing it as a market share play rather than a high-margin item.

FAQ
Can the Remax 100W charge a 16-inch MacBook Pro?
Yes. In single-port mode, USB-C1 delivers a full 100W, which is sufficient to charge a 16-inch MacBook Pro even while in use (though it will charge slowly under heavy workloads like video rendering). The charger negotiates PD 3.0 correctly with Apple’s charging profiles.
Does it support Samsung 45W Super Fast Charging?
It does. The PPS profiles include 3.3–11V/5A and 3.3–21V/5A, which cover Samsung’s 45W Super Fast Charging requirement. We confirmed this works with the Galaxy S24 Ultra, Galaxy S25, and Galaxy Tab S9 without issue.
Is it safe to use as a bedside charger?
Yes. The LED indicator is dim enough not to disturb sleep, and under typical overnight charging loads (a phone and a watch, for example), the charger barely gets warm. It also meets V0 flame-retardancy standards and includes over-voltage, over-current, short-circuit, and over-temperature protection. That said, its size may make it awkward on crowded nightstands — it is not the most compact charger at this wattage.
How does it handle power surges or unstable grid power?
The internal power management IC includes surge protection and input voltage regulation. Chinese user reviews from regions with less stable power infrastructure report no issues. The wide 100–240V input range also makes it suitable for international travel, though you will need a plug adapter for regions with different outlet standards.
What happens if I draw more than 100W total across all ports?
The charger enforces its power budget strictly. If total demand exceeds the charger’s allocation, it will redistribute power according to its priority scheme (C1 gets priority, followed by C2, then A ports). Devices will simply charge at a slower rate rather than shutting off. The charger does not allow total output to exceed its rated capacity.
Final Verdict
The Remax 100W GaN charger is the definition of punching above your weight class. It delivers genuine 100W output, competent multi-port charging, respectable thermal performance, and solid build quality — all at a price that undercuts the established players by 30–50%. Is it perfect? No. The invisible port labels, lack of included cable, and shorter warranty are real downsides. And as a relatively new entrant in the GaN charger space, Remax does not have the track record that Anker or UGREEN users take for granted.
But for anyone who wants a no-nonsense, high-wattage charger and does not want to pay the premium for a brand name, the Remax 100W is an easy recommendation. It is the charger you buy when you stop caring about the logo on the casing and start caring about watts per dollar.
Score: 7.5/10
Deductions for the lack of included cable, microscopic port labels, and lingering questions about long-term durability. Everything else about this charger genuinely exceeds expectations at this price point.
