If you are looking for a true 5G portable router that can turn any SIM card into a high-speed Wi-Fi hotspot for your team, Huawei’s 5G Mobile WiFi series is definitely the way to go.
Today, we are comparing the E6878-370 (5G Mobile WiFi Pro) and the E6878-870 (Standard 5G Mobile WiFi). They look almost identical, but that small “Pro” upgrade makes a surprisingly big difference in real-world use.
What They Have in Common
Both devices are powered by Huawei’s high-performance Balong 5000 chipset and deliver the same core specs:
- 5G Speeds: Up to 1.65 Gbps download / 250 Mbps upload (NSA+SA modes).
- 4G Fallback: Up to 300/75 Mbps.
- 5G Bands: n41, n77, n78, n79 (plus a full suite of global LTE bands).
- Dual-Band Wi-Fi: 802.11ac (300 Mbps on 2.4 GHz + 867 Mbps on 5 GHz).
- Connectivity: Supports up to 32 simultaneous devices.
- Display: 1.45-inch color LCD for quick status checks.
- Design: Nano-SIM slot, sleek white finish, and support for the Huawei AI Life App.
In short, when it comes to connectivity, they are twins. Whether you are streaming 4K video on a train or hosting a multi-device video call, you will get the same speeds on either device under the same network conditions.
The Real Differences
The value of the “Pro” label comes down to power and versatility:
Battery Life and Power Bank Functionality
The E6878-370 (Pro) packs a massive 8000 mAh battery—double the 4000 mAh found in the E6878-870 (Standard). In practical terms, the Pro version easily lasts 10–12 hours under heavy 5G use, while the Standard version clocks in at about 5–6 hours. Even better, the Pro version doubles as a portable power bank.
Charging and Ports
- Pro Version: Supports 40W SuperCharge input and features a USB Type-A output port to charge your phone or tablet via cable. It also supports reverse wireless charging.
- Standard Version: Uses a single USB Type-C port (18W charging) and lacks any output ports for external charging.
Size and Weight
Both share the same footprint (148 × 72 mm), but the Pro version is significantly thicker (18 mm vs. 12 mm) and heavier (280g vs. ~175g) due to the larger battery. It still fits in a pocket, but you will definitely notice the extra heft.

Price
The Pro version typically carries a premium of $50–$80. This is a reasonable jump considering you are getting twice the battery capacity and added charging features.
Which One Should You Buy?
Choose the E6878-370 Pro if: You travel frequently, hate hunting for power outlets, or need to charge other gadgets on the go. The extra battery and USB-A port make it a true “all-day” companion.
Choose the E6878-870 Standard if: You prioritize portability and a lightweight design. If you don’t need the power bank feature and want to save some money, it remains an excellent 5G hotspot.
