There is a portable 4G router modem on Amazon for €34, an ASUS for €77: the right time to get one

Here are two devices that meet different needs, although both use a SIM card to bring the Internet where there is no fixed line. The first is a portable hotspot router designed for travel, remote work, fairs, and students; the second is a more structured LTE modem router suitable for those seeking a 4G+ connection to use as a main or backup network at home and in the office.

The 2100 mAh battery offers up to 8 hours of intensive use, a useful feature for those who frequently move and do not want to depend on a power outlet. It is primarily for those needing a personal Wi-Fi network always available on the move. The compact format allows it to fit in a bag or backpack, while WPA/WPA2 protection and PIN code management add a layer of security useful in public or shared environments.

The ASUS 4G-AC86U is a step up in category and performs like a true home 4G+ modem router. The LTE Cat.12 connectivity reaches up to 600 Mbps in download and 150 Mbps in upload, values that are much higher than the Strong portable router, making it suitable for streaming, smart working, video conferencing, and home networking without fiber.
The difference is not just speed. The ASUS 4G-AC86U integrates advanced features such as Adaptive QoS, VPN server and client, AiProtection Pro, parental controls, AiCloud 2.0, media server support, and compatibility with Time Machine for Mac backup. Additionally, it offers a guest network with a captive portal, useful in professional environments or hospitality facilities.
From a radio perspective, ASUS supports multiple bands: 4G FDD-LTE, TDD-LTE, and 3G UMTS, with an adjustable LTE antenna to optimize signal reception based on location. This setup makes it more flexible in areas where mobile coverage is not always perfect and requires a more stable device than a simple pocket hotspot.
The choice, therefore, depends on actual usage: the first device proposed is ideal for those wanting simple, affordable, and portable mobile Internet; the ASUS 4G-AC86U is better suited for those seeking a complete, faster network with advanced router functions. At €34.90, the first is a travel device, while at €77.99, the second aims to replace or supplement a fixed connection with more technical margin.
