Why I won't buy another portable power station if it doesn't have this useful feature

"The RIVER 3 Plus is a portable power station with 286Wh of capacity that measures 9.2 × 9.1 × 5.8 inches and weighs 10.4 pounds. It has three AC outlets -- one on the front, two on the rear -- good for 600W continuous load and a surge load of up to 1,200W. That power capacity is smaller than the 768Wh of the RIVER 2 Pro, but it's also almost 7 pounds lighter."

"The batteries are automotive-grade LiFePO4 cells designed to last 3,000 recharge cycles -- which is around 10 years of everyday use -- before their capacity drops to 80%. The cells are protected to IP54 standards (protected against a limited amount of dust and water splashes from any direction), and the shell of the unit is made from a fire-retardant polymer designed to survive a 3-foot/1.5-meter drop."

"Regular readers will know that I'm a huge fan of EcoFlow's RIVER series of portable power stations. The has been with me on many an adventure, including on a UFO hunt to Rendlesham Forest, the location of Britain's own Roswell UFO incident . It's also been with me in my hammock on numerous cold, wet nights. It's been one of those Goldilocks power stations -- not the smallest, and definitely not the biggest."

The RIVER 3 Plus trades higher capacity for reduced weight and size compared with the RIVER 2 Pro.
