With 1800W continuous and 2700W surge, this unit can handle most small- to medium-sized appliances you’ll use outdoors or in a short home outage.
AC outlets and real-world appliance use
You’ll find several AC outlets that let you run laptops, lights, CPAP machines (check your model’s startup watt), mini-fridges, small microwaves, and power tools within the 1800W continuous limit. For high-draw appliances like large electric heaters or full-size ovens, the DELTA 2 won’t be suitable as a primary power source.
DC and USB outputs
The inclusion of multiple USB-A, USB-C, and 12V DC outlets means you can charge phones, tablets, cameras, and run 12V devices directly. USB-C PD ports are especially useful for fast-charging laptops and phones without adapters.
Solar charging performance
The included 2PCS 100W 12V solar panels pair nicely with the DELTA 2. The panels claim up to a 23% conversion rate, which is competitive for portable panels and helps you recharge faster under good sunlight.
Typical solar charge times
If you use the two included panels under ideal sun conditions, you can expect around 5.1 hours to fully charge the DELTA 2. If you add a third compatible panel, charge time can drop to around 2.6 hours. Real-world times will vary depending on sun angle, shading, temperature, and panel placement.
Solar setup tips
Position the panels facing the sun with minimal shade, use the built-in stands or mounts where possible, and keep them clean. If you’ll be off-grid frequently, plan panel placement to maximize midday sun and consider a third panel for faster turnaround.

You have multiple charging pathways: solar, AC wall charging, and vehicle charging. This flexibility helps you adapt to various scenarios like home outages, road trips, or backcountry camping.
Fast charging capabilities
The DELTA 2 offers faster-than-average recharge times for its class: with two panels it’s about 5.1 hours solar, and with AC charging you’ll see substantially shorter times depending on the AC adapter and mains supply. This means you can get back to full power quicker after a long usage day.
Charging simultaneously and pass-through
You can use multiple inputs concurrently in many setups — for instance, solar plus AC — depending on the system’s input design. The unit typically supports pass-through so you can use power while charging, which is handy during long events or outages.
Expandability and modular options
One of the strengths of this model is that you can increase capacity from the base 1kWh to as much as 3kWh by adding extra batteries. That gives you flexibility if your power needs grow.
Adding extra batteries
If you plan to expand, you’ll have the option to connect additional battery modules compatible with the DELTA line. This is useful if you want longer runtimes for refrigerators or to power more devices during extended outages.
When to expand and when to stick with base unit
If your needs are mostly portable charging, weekend trips, or brief power outages, the base 1024Wh should suffice. If you anticipate extended blackouts, powering several large appliances, or supporting a household for many hours, expanding capacity is a smart move.
Real-world run-time estimates
Understanding run times helps you plan better. Below are general estimates for what to expect, remembering that actual times vary by device efficiency and usage patterns.
Typical device runtimes
- Smartphone (25W): dozens of charges, often 30+ full charges.
- Laptop (60W): 10–12 hours depending on workload.
- Mini fridge (60–100W typical cycling): 10–16 hours depending on compressor duty cycle.
- CPAP (30–60W typical): 12–20 hours depending on mask heating and humidifier use.
- Small microwave (700–1000W): 1–1.5 cycles (short bursts) — not ideal for prolonged microwave cooking.
- Electric grill or high-wattage heaters: not supported for extended periods due to 1800W continuous limit.
How to estimate your own use
Add up the wattages of devices you’ll run simultaneously to ensure you stay below the 1800W continuous limit. Multiply device wattage by the hours you need to operate, and compare that to 1024Wh to estimate run time. If you plan concurrent heavy loads, consider expanding capacity.
