Product Info

The TOMSING 4-in-1 USB to USB C Cable is an entry-level to mid-range accessory released in late 2024. It is available on Japan for approximately ¥1,280, making it an affordable option for users seeking a multi-functional cable.

In the market, this cable positions itself as a budget-friendly multi-cable solution. While it lacks premium branding or MFi certification, its price-to-feature ratio is excellent for users who need basic charging and data transfer across multiple device types.

Best Use Cases

Frequent travelers and business professionals: Carry one cable instead of three. Charge both a USB-C laptop and a Lightning iPhone without swapping cables. However, if you need to charge multiple devices simultaneously, consider a multi-port charger instead. Multi-device users: Ideal for those who switch between Android and iOS devices, or between a tablet and a laptop. The cable reduces desk clutter and eliminates the need to carry separate cables for each device. Not recommended for high-speed data transfers (e.g., external SSDs) due to USB 2.0 speed limits. * Budget-conscious students and young professionals: At around ¥1,280, this cable offers excellent value. It covers most everyday charging needs without breaking the bank. Be aware that achieving 100W PD charging requires a compatible PD charger on the power source side.

Things to Consider

Actual charging speed depends on both the connected device and the power adapter. For example, iPhone 15 series typically max out at around 27W, while MacBook Air may reach 60W. The cable's data transfer is limited to USB 2.0 (480 Mbps), so it is not suitable for frequent large-file transfers or backups. The silicone material, while flexible and durable, tends to attract dust and lint more than PVC or braided cables. Regular cleaning may be needed. Additionally, the Lightning connector is not MFi certified, which could occasionally trigger compatibility warnings on iOS devices. If you rely heavily on Apple's ecosystem, an MFi-certified cable might be a safer choice. ## FAQ
Q: Can I fast charge my iPhone 15 Pro Max with this cable? A: Yes, using USB-C to USB-C connection with a PD charger, you can achieve up to 27W charging. However, since the cable is not MFi certified, you may occasionally see a compatibility warning on iOS. Q: Can I charge a laptop and a smartphone at the same time? A: No, this cable connects only one device at a time. For simultaneous charging, you would need a multi-port hub or charger. Q: What is the data transfer speed? A: It supports USB 2.0, so the maximum speed is 480 Mbps. This is fine for photos and documents, but large video files or backups will take significantly longer.
