Design and Portability
The AllPowers R4000 boasts a sleek, modern design. It's noticeably large, however, and its nearly 100lb weight makes it less truly 'portable' than some competitors. Despite this, AllPowers has incorporated thoughtful features to ease transport.

Two top handles, coupled with comfortable orange gel padding, improve the carrying experience. A cleverly designed, retractable handle extending from the base, coupled with heavy-duty wheels in the rear and rubber stoppers in the front make maneuvering surprisingly easy, even over uneven terrain.

Ports and Connectivity
The R4000 offers a comprehensive array of ports to meet diverse charging needs. These include a 12V car adapter port (10A max), two 100W USB-C ports, four USB-A ports (two 12W, two 18W), and multiple AC outlets (one 30A, four 20A).

The rear panel provides access to AC input, an expansion port, and three solar panel inputs. This makes the station adaptable to various power sources and expandability.

User Interface and App
A full-color touchscreen provides a user-friendly interface, displaying battery level, toggles for DC and AC power, input levels, and Wi-Fi status. The screen's modern graphics are a welcome departure from some older power station displays.

A companion app offers additional controls, including language selection, frequency (50/60Hz), operating modes (stay-on, timed shutdown), buzzer control, backlight adjustment, and data logging. The app is compatible with Bluetooth and Wi-Fi.

Performance and Battery Life
The R4000 utilizes a LifePO4 battery, rated for 80% capacity after 3,500 charges, offering a lifespan of over 10 years with daily use. It boasts a maximum charging speed of 2000W (0-100% in 2 hours) via AC, and simultaneous solar and AC charging is supported (3000W max, prioritizing solar power).

A real-world test yielded a usable capacity of 86.1%, surpassing many competitors. The inverter includes a safety feature to prevent complete battery drain.

Real-World Testing and Power Output
A test running various household appliances (lights, fan, router, smart devices, phone, laptop) drew only 250W. This demonstrates the R4000's efficiency for everyday needs. Even high-power appliances can easily be run.

Adding two 1500W electric heaters increased the load to nearly 2800W, leaving ample capacity for additional devices. This highlights the power station's suitability for home backup in power outages.

Solar Panel Compatibility
The review also includes the AllPowers SP039 600W solar panel, a large panel (71x70 inches) ideal for various mounting options (RV, deck, fence, etc.).

Testing yielded around 480W under less-than-ideal weather conditions, suggesting a potential output of 500-540W on a sunny day. This would significantly supplement the R4000's charging capabilities.

Conclusion
The AllPowers R4000 is a high-capacity portable power station that delivers on its promise of a reliable home backup solution. The large capacity, combined with thoughtful design features (retractable handle, wheels), makes this unit powerful and convenient.
While the weight is a consideration, its performance, extensive port selection, and user-friendly interface outweigh this for many. The inclusion of a useful app further enhances its practicality. While not cheap, for those needing a robust home backup power solution, the AllPowers R4000 is a top contender.
