It’s important to bear in mind that AC (alternating current) and DC (direct current) power different types of appliances and devices.
AC Power is the same type of electricity supplied by the grid and used in most household tools and appliances such as standard refrigerators, desktop computers, and power equipment.
DC Power, on the other hand, is what’s stored in batteries and energizes electronic devices like smartphones and laptops. It’s what powers mobile devices, RV accessories like coolers and air pumps, and other low-voltage equipment.
The true versatility of portable power stations like the Delta Pro series lies in their ability to provide both AC and DC electricity, enabling you to run a wide range of devices simultaneously and manage battery energy more efficiently.

The charging speed of portable power stations is another crucial factor to consider, since it determines how quickly the device's battery can be replenished. The rate of recharging varies between AC grid power and DC solar power.
AC power provides a rapid and reliable charge, ideal for quick top-ups in settings served by the grid, while charging with DC solar power offers a slower, more eco-friendly alternative that’s ideal for off-grid situations. A power station that taps both sources of energy ensures you’ll have access to electricity in almost any situation.
Charging with AC power from the grid happens at a portable power station’s maximum rated speed—particularly beneficial when quick turnaround times are needed, such as when a looming storm threatens to disable the grid, or when you’re in a hurry to hit the road in an RV.
Despite being slower, solar charging is perfect for off-grid use. Sunlight is free, of course, and provides an invaluable resource during extended grid outages, or in remote locations to enable sustainable living.
