Pros
- Slim 0.55-inch design according to the listing
- USB-C and USB-A connectivity
- Up to 65W claimed output with PD 3.0 and QC 4.0
- Foldable wall plug for easier packing
Cons
- Power distribution during two-device charging is not specified
- Amazon listing gives contradictory total-port information
- Only 110V AC input is specified
- Certification details and an included cable are not clearly documented
Bottom line
The RUIDUN 65W Flat GaN Charger is a practical choice for travelers or desk users who want one slim adapter for a USB-C laptop and a second device. Its foldable plug and mixed USB-C/USB-A connectivity are useful, but buyers should verify the port count, output split, and electrical certifications on Amazon because the listing is inconsistent or silent on those points.
Buy this if
- You want a thin charger that takes up less room in a laptop bag.
- Your everyday devices include both newer USB-C gear and older USB-A cables.
- You need up to 65W for a compatible laptop, tablet, handheld, or phone.
- A foldable US-style wall plug matters for travel or shared workspaces.
Skip if
- You need confirmed charging wattage from both ports when they are used together.
- You want three or more charging ports for a larger desk setup.
- You need a charger explicitly documented for worldwide mains voltage.
- You prefer a model with clearly published safety certification information.
Will it actually charge your laptop?
Wattage is the whole game here, and the number on the box is the total across all ports — not what any one device gets. Getting this wrong is why a charger feels slow rather than broken.
What this listing states
- USB-C output — listedThe connector laptops and modern phones charge over. USB-A only means phone-speed at best.
- 60W or more stated — listedRoughly the floor for charging a laptop at full speed while you use it.
- Multiple ports — listedConvenient — but the total wattage splits between whatever you plug in at once.
- GaN construction — listedMeaningfully smaller and cooler than older silicon bricks at the same wattage.
- Retractable or foldable — listedA small thing that decides whether it survives a bag without snagging everything.
- Battery capacity stated — not listedFor power banks: capacity in mAh, which also decides whether an airline lets it in your carry-on.
Do the wattage math before you buy
- Find the watt rating printed on your laptop's original charger — that is your floor, not a target.
- Charging a second device splits the budget: a 65W two-port charger may hand the laptop only 45W.
- Under 30W will trickle-charge a laptop and can lose ground entirely while you are working.
- Phones top out around 20–30W, so wattage beyond that aimed at a phone is wasted money.
- Flying with a power bank? Airlines generally cap carry-on at 100Wh — roughly 27,000mAh at 3.7V.

Performance & everyday use
The listing specifies PD 3.0 and QC 4.0 support, with up to 65W output for compatible equipment such as MacBooks, iPhones, Samsung phones, and Steam Deck. That output is suitable on paper for many thin-and-light laptops, although it may not satisfy power-hungry mobile workstations or gaming laptops that expect a higher-wattage proprietary adapter.
Its main everyday advantage is the combination of USB-C and USB-A. That lets you keep using an older watch, accessory, or phone cable while charging a USB-C computer. However, the listing does not publish the power allocation when both connections are active. As with many multiport chargers, connecting a second device may reduce the power available to the laptop or briefly renegotiate charging. Buyers who depend on a specific dual-device output should confirm the current Amazon documentation before ordering.
There is also a listing discrepancy worth noting: the marketing bullets describe two ports, and the connector field names USB Type-A and USB Type-C, but the specification table says “Total USB Ports: 1.” The product title and images should be checked to confirm the exact configuration being shipped.
Build, comfort & setup
RUIDUN describes the black charger as 0.55 inch thick and includes a foldable plug. The flat body should pack more neatly than a conventional block, though a wide charger can still interfere with an adjacent receptacle depending on the outlet or power strip orientation.
Setup is plug-and-charge, with no software required. The listing mentions overcharge and overheating protection and says GaN technology improves efficiency and reduces heat, but those are manufacturer claims rather than independent test results. No charging cable is identified in the included-components information, so plan to supply a properly rated USB-C cable. The table specifies 110V AC input; it does not clearly establish broad international voltage support.
Value & alternatives
This charger offers competitive functionality if your priority is a slim adapter with one modern port and one legacy port. Check Amazon for the current price and compare it with models that clearly publish single-port output, simultaneous-use power distribution, input-voltage range, and recognized certification details.
A simpler single-port charger may be the better choice if you only charge a laptop. For a permanent desk, a larger three-port or four-port unit provides more flexibility. Frequent international travelers should favor an alternative that explicitly lists a broad input-voltage range rather than assuming device compatibility also means worldwide wall-power compatibility.
Verdict
The RUIDUN 65W Flat GaN Charger has a sensible travel-friendly shape, useful USB-C and USB-A connections, and enough claimed output for many mainstream portable devices. It is worth considering for a compact two-device kit, but the unclear shared-output behavior, contradictory port count, and limited input-voltage documentation keep it from being a universal recommendation.
