Kunpeng Infinite (NRadio) C2000 MAX 5G CPE Unboxing and Review.

I bought this 5G CPE to replace my broadband. My current rental broadband costs 100 yuan per month for 300 Mbps, which is a bit expensive. A few days ago, I purchased the ZTE F40 portable WiFi, but I found its performance insufficient, so I decided to try this model.

User manual

Removing the manual reveals the Kunpeng Wireless C2000MAX.

Below it are the power adapter and power cable.

The power cable has dual Type-C male connectors, one of which is an angled connector. The power adapter model is S9-PD20W-GAN, manufactured by Shenzhen Wangyou Electronic Technology Co., Ltd., with supervision by Shenzhen Jiahaoxin Electronic Co., Ltd. Input: 220VAC, Output: 5V/3A, 9V/2.22A, 12V/1.67A. The model suggests it might be a GaN (Gallium Nitride) charger that supports the PD protocol with a maximum output power of 20 watts.

China Telecom 5G

Network information shown below, signal strength -94dBm, band n78 (3.3GHz-3.8GHz), relatively weak signal strength with no 5GA or carrier aggregation triggered (occasionally appears, likely due to base station coverage issues).

Left: C2000MAX, download speed 346.24Mbps, upload speed 65.4Mbps;

Right: Huawei Pura70 Pro+, download speed 283.31Mbps, upload speed 30.75Mbps.

China Mobile 5G

Network information shown below, signal strength -79dBm, band n41 (2.5GHz-2.7GHz), with decent signal strength.

Left: C2000MAX, download speed 357.84Mbps, upload speed 37.7Mbps;

Right: Huawei Mate70 Pro+, download speed 381.09Mbps, upload speed 37.42Mbps.

Maximum WiFi Speed

The maximum negotiated speed for the 5GHz WiFi band is approximately 2401Mbps.

Power Consumption Test

Applying 5V input voltage, the device fails to start properly, with current fluctuating within 0.2A. The USB-A port outputs 5V/2A.

On China Telecom 5G, with one WiFi device connected but no data transfer, power consumption is around 4.6W.

On China Telecom 5G, with two WiFi devices connected and speed testing, power consumption is around 9.5W.

Data Plan Pricing

The version I purchased includes one built-in data SIM and supports two additional SIM cards. The built-in card is from China Mobile.

1TB per month, annual plan 599 yuan (approximately 49.9 yuan/month), monthly plan 79 yuan/month, reasonable pricing.
