What Runs, and for How Long
- A 100 W fridge runs about 8 hours on the GPP-1000, 16 hours on the GPP-2000 and 32 hours on the GPP-4000.
- A 60 W laptop plus router and lights runs roughly 12 / 24 / 48 hours across the three models.
- An 1800 W kettle runs on the GPP-4000 only.
Charging Options
Mains AC (500 / 800 W), solar (300 / 550 / 1200 W) or a car socket. All three charge while supplying load. The GPP-4000 accepts solar over an 18-110 V window.
Outputs
Pure sine wave 230 V AC, four 12 V DC 5521 ports, USB-C PD 20 W and USB-A QC 20 W.

Common Questions
How long will a 1 kWh portable power station run a fridge?
A SiRay GPP-1000 holds 1004.8 Wh of LiFePO4 capacity. Running a 100 W camping fridge, the GPP-1000 supplies it for about 8 hours on battery alone. With 300 W of solar input connected, the fridge runs through daylight while the pack recharges.
Can a portable power station charge while it is powering devices?
Yes. All three SiRay GPP models support pass-through charging. The GPP-1000 accepts 500 W from mains AC or 300 W from solar, the GPP-2000 accepts 800 W AC or 550 W solar, and the GPP-4000 accepts up to 1200 W solar over an 18-110 V input window while continuing to supply the AC outlets.
What is the difference between the GPP-1000, GPP-2000 and GPP-4000?
The GPP-1000 stores 1004.8 Wh and outputs 500 W AC at 10.5 kg. The GPP-2000 stores 2009.6 Wh and outputs 1000 W across two AC outlets at 18.5 kg. The GPP-4000 stores 4019.2 Wh and outputs 1800 W with UPS transfer switching. All three use LiFePO4 cells and provide USB-C PD 20 W and USB-A QC 20 W.
What outputs does a SiRay portable power station have?
Every SiRay GPP model provides pure sine wave 230 V AC outlets (one on the GPP-1000, two on the GPP-2000), four 12 V DC 5521 ports at 4 A each, USB-C with 20 W Power Delivery and USB-A with 20 W Quick Charge.
