Overview

The Fujisoft +F FS040W is a SIM-free 4G LTE mobile router that comes bundled with a dedicated shock-absorbing screen protector. Its standout feature is the built-in 3,060mAh battery, which delivers up to 20 hours of continuous operation on a single charge. This makes it an excellent choice for creating a Wi‑Fi hotspot in your car, at home, or on the go without needing a constant power source. Beyond being a router, the FS040W includes a battery power supply mode that lets you charge other devices like smartphones via its USB Type-C port. In an emergency or during a power outage, it doubles as a portable power bank. The companion +F Setup Tool app provides real-time battery level and data usage monitoring, adding to its convenience.

Connectivity & Compatibility

The FS040W accepts a single Nano SIM card and is fully SIM-unlocked, supporting major Japanese carriers (docomo, au, SoftBank, Rakuten Mobile) as well as various MVNOs. It operates on dual-band Wi‑Fi (2.4GHz and 5GHz) with maximum theoretical speeds of 150Mbps down and 50Mbps up. For charging and data tethering, it features a USB Type-C port. The package includes an AC adapter and USB-C cable, so you can start using it right out of the box.

Product Info

Released in late 2023, the FS040W typically retails for around ¥13,000–¥14,000, positioning it as an entry-to-mid-range mobile router with strong battery life. The manufacturer provides a standard one-year warranty. In the box you'll find the router, quick start guide, warranty card, safety instructions, USB-C cable, AC adapter, battery pack, and one screen protector film. It competes well against similarly priced models by offering both long runtime and a power-bank feature.

Best Use Cases

Car Wi‑Fi on a budget: The FS040W is designed for both car and home use. Its internal battery means you don't need a constant power source, making it ideal for road trips or camping. However, it lacks 5G support, so heavy streamers may want a faster option. Emergency preparedness: With 20 hours of continuous operation and the ability to charge other devices, this router is a solid addition to any emergency kit. Just note it's not water or dust resistant, so keep it dry. * Cost-conscious users with MVNO SIMs: Because it's SIM-unlocked, you can pair it with a cheap data-only SIM from any provider. This is perfect for users who want a dedicated mobile hotspot without a long contract. But if you regularly consume large amounts of data, be aware of potential speed throttling. ## FAQ
