Best Buy is running a President’s Day sale on EcoFlow portable power stations, which can keep essential devices running during outages, or provide electricity for RVs and off-grid setups. And our number one performer is in the sale, with the EcoFlow Delta Pro 3 now $2000 (was $3400) at Best Buy.
This portable power station is built as a serious home backup power station rather than a simple portable battery. It has a base capacity of 4,096 watt-hours, which is enough to run core appliances like a refrigerator, lights, networking gear, and small electronics for many hours.

The unit delivers 4,000 watts of continuous output with an 8,000-watt surge, and it supports both 120-volt and 240-volt appliances from a single unit.
That allows it to run larger household loads such as central air conditioners, well pumps, or electric dryers, tasks that most portable power stations cannot handle.
Multiple units can also be connected in parallel to reach up to 12,000 watts for even higher-demand setups.
The Delta Pro 3 is designed for fast, seamless backup. It features a 10-millisecond automatic switchover, which helps protect sensitive electronics like computers, servers, or home entertainment systems during outages.
It also supports several charging options, including standard AC outlets, solar panels, vehicle charging, and EcoFlow’s smart generator.
Under ideal conditions, it can charge from empty to 80% in about 50 minutes.
Despite its large capacity, it remains portable with built-in wheels and a handle. The LFP battery chemistry is rated for around 4,000 cycles and roughly a 10-year lifespan.
You get a five year warranty for parts and labor.
In our five-star review, we called it "an outstanding, high-capacity power station with incredible output, rapid charging, and smart home integration" and said it was the "ultimate power solution for homes, RVs, and professionals needing a versatile power station."
