Description
The PEAK 1.8 is a versatile and powerful portable power station, delivering reliable energy wherever you go. Compact yet robust, it provides ample power for a wide range of devices, from small electronics to higher‑demand appliances. Built with a durable exterior and a user‑friendly interface, it is ideal for camping, vanlife, home backup, and professional use. The integrated MPPT charge controller enables efficient solar charging, allowing you to stay off‑grid for longer. The pure sine wave inverter ensures compatibility with sensitive electronics, and the Backup Power Supply function switches from grid to battery in 8–20ms during power cuts.
The PEAK 1.8 uses automotive‑grade LiFePO4 batteries, known for safety and longevity. These cells can be cycled 3500 times before capacity drops to 80%. With 1024Wh capacity and optional expansion to 4096Wh, it offers substantial energy reserves. The advanced BMS provides protection against over‑voltage, low‑voltage, overheating, overloads, and short circuits. An automatic battery cell heating function activates when charging below 0°C (32°F), ensuring safe operation in cold climates.
With 11 output ports, the PEAK 1.8 powers multiple devices simultaneously:
AC: 3 × 220V–240V/50Hz sockets
USB‑A: 2 ports
USB‑C: 2 ports
DC 5525: 1 port
Wireless Charging Pad: 1
Aux Car Port: 1
XT60 Output: 1
Suitable for smartphones, cameras, laptops, fridges, diesel heaters, and other DC devices.
