It is rated for up to 240W over USB PD 3.1 and has a braided nylon jacket. In short, this is a charge-only cable for moving a lot of power over a very short distance. Think of a power bank and a phone, or a charger and a device sitting right beside it. It does not support data transfer, so do not buy it to connect hubs, docks, monitors or external SSDs. The connectors are reinforced to handle daily plugging, unplugging and bending. A built-in E-marker chip tells the charger and the device how much current the cable can carry. This helps them settle on the right power level and lowers the risk of overcharging or overheating. Any charge above 100W under PD 3.1 requires a 5A cable with an E-marker, so the chip is essential for a cable rated at 240W. ## Where the Short Length Helps At about 15cm, this cable is far shorter than the usual 1m cable. It fits situations like these: carrying a power bank stacked with a phone in a bag, placing a laptop or tablet right next to a charger on a desk, or connecting a charger by a power strip to the device beside it. In each case, extra cable length just tangles or snags. A short cable leaves almost no slack and keeps things tidy. On the other hand, it cannot reach you on the sofa or in bed while you use your phone. It also cannot run from a charger under the desk up to a laptop on top. This is not a replacement for all your charging cables. Buy it when you want one extra cable for a specific short-range setup. ## Compatibility Guide Both ends use USB Type-C connectors. The cable can charge a wide range of USB-C devices, including the iPhone 17/16/15 series, Galaxy S25/S24/S23, MacBook, iPad, Steam Deck and Nintendo Switch. It is rated for 18W to 240W, so one cable covers everything from fast-charging a phone to charging a laptop. | Use | Works? | Notes | |---|---|---| | Charging phones and tablets | Yes | Charging speed depends on what the device and charger support | | Charging laptops | Yes | Above 100W only if both the charger and the laptop support PD 3.1 (EPR) | | Connecting a power bank | Yes | The use where the short length helps most | | Charging a Steam Deck or Nintendo Switch | Yes | Charging only; no video output through a dock | | USB-C hubs and docks | No | No data transfer | | Video to a USB-C monitor | No | Carries no video signal | | File transfer or phone backup to a PC | No | Charge-only | | USB-A chargers | Not directly | Both ends are USB-C, so you need a charger with a USB-C port | The biggest trap is assuming that a 240W cable means 240W charging. Standard USB PD (SPR) tops out at 100W. Anything above that requires PD 3.1 EPR support on both the charger and the device. The cable is only a path that can safely carry up to 240W. The charger and the device decide how much power actually flows. Phones and handheld consoles normally charge at far less than the cable's limit. The second trap is assuming that anything with a USB-C plug will just work. This cable is charge-only, so plugging it in does nothing except charge. To import photos from a phone to a PC, or to use a keyboard and mouse through a USB-C hub, you need a separate data-capable cable. ## Product Info | Item | Detail | |---|---| | Cable length | 0.5ft (about 15cm) | | Max power delivery | 240W (PD 3.1) | | Connectors | USB Type-C (both ends) | | Material | Braided nylon | | Data transfer | Not supported (charge-only) | | Quantity | 2 cables | SUNGUY is an accessories brand, and this product is sold through online retailers. Its price has moved a lot. Amazon prices were: That is roughly half the price in about two months. All of these are prices at the time of capture and change often with sales and stock. Check the product page for the current price. The information available does not state the warranty period or whether the cable is USB-IF certified. Check the product page for both. ## Comparison With Alternatives Even among USB-C to USB-C cables, the right choice depends on whether you care most about length, power or data. Below are cables we cover that are often compared with this one. For detailed specs of the other products, see their articles and product pages. | Product | Length | Key trait | Best for | |---|---|---|---| | SUNGUY (this product) | ~15cm, 2 cables | 240W PD 3.1, charge-only | Short-range charging | | Belkin BoostCharge braided 240W PD 3.1 | 2m | USB-IF certified | High-power charging at a distance | | Cable Matters 40Gbps USB4 | 0.3m | 40Gbps data | Short links to docks and SSDs | | Plugable Thunderbolt 3 | 80cm | 40Gbps plus 100W charging | Data and power in one cable | | Anker 310 durable nylon | 0.9m, 2 cables | Two-pack at a standard length | Everyday charging | This cable's strength is that it combines three things: it is short, it is rated for 240W, and it comes as a two-pack. Its weakness is that it carries no data. If you want a short cable for a dock or SSD, a data-capable option such as the Cable Matters 0.3m USB4 cable fits better. If your laptop sits away from the charger, a longer cable such as the 2m Belkin is more practical. If third-party certification matters to you, the Belkin states USB-IF certification. ## Recommended Users - People who carry a power bank stacked with a phone: at 15cm there is almost no slack to tangle in a bag. - People who charge devices right beside the charger: a desk with the adapter next to a laptop or tablet stays tidy. - Owners of high-output chargers or power banks: the cable is rated for 240W, so it is unlikely to be what slows charging down. - People who want the same setup in two places: the two-pack lets you keep one at home and one in your bag, or one for a power bank and one for your desk. - People who value a tough jacket: braided nylon and reinforced connectors resist fraying and bending better than typical rubber cables. It is not a good fit for: - Anyone who needs data transfer or video output - Anyone who wants to charge on the sofa or in bed - Anyone who needs to run a cable from under the desk up to the desktop It is also a poor choice as your first or only USB-C cable. It works best as a second or third cable alongside the ones you already use. ## Before You Buy This cable is charge-only. It does not support file transfer or video output. If you need data through a USB-C hub or dock, get a separate data-capable cable. It looks just like any other USB-C cable, so label it as charge-only to avoid mixing it up later. At 0.5ft (about 15cm), the cable is very short. It may not reach if your laptop and charger sit apart on a desk. Check the product page to see whether the stated length includes the connectors. Also, if you hold a phone connected to a power bank, a short cable has nowhere to flex. That puts stress on the base of the connectors. Rest the power bank on a table, or strap it to the phone while in use. The full 240W is only available when you pair a PD 3.1 charger with a PD 3.1 device. Otherwise, the charger's own maximum sets the limit. If charging feels slow, check what the charger and the device support first.

Can I transfer photos from my phone to a PC with this cable? ** A. No. It does not support data transfer; it is a charge-only cable. **Q. Will any charger deliver 240W through it? ** A. No. Power above 100W flows only when both the charger and the device support PD 3.1 (EPR). Otherwise you get the charger's or device's maximum. **Q. Does it work with iPhone 15 and later? ** A. Yes. It charges the iPhone 17/16/15 series with USB-C ports. Charging speed depends on the iPhone and the charger. **Q. Can I use it with a Nintendo Switch or Steam Deck dock to output video to a TV? ** A. No. The cable carries no video signal. Use it only for charging the device itself. **Q. Is 15cm really long enough? ** A. Yes, if the devices are stacked or placed right next to each other. If your charger and device are more than 15cm apart, choose a longer cable. ### Product Disclosure (Amazon) - Manufacturer: SUNGUY - Seller: Amazon US - Fulfilled by: Amazon US - ASIN: B0GHQ544RH - Note: This article covers a manufacturer-made product based on Amazon listing details.
