Key stroke per hour test

Most accurate during my final test after three months in storage.

It had a higher percentage of energy efficiency against its stated watt hour potential in the large appliance test and long-term storage test. While it had a more accurate reading in both tests with a fresh charge, it turned off with still 2 percent left on the onboard display after the long-term storage test. However, it did worse than the EcoFlow in the most important test

Across the last 180 daysAverage Price: The average price across the last 180 days Price per Usable Watt Hour: The average price of the unit divided by the usable kWh from the high-draw (~380W) testing scenario. This provides a sense of the relative value of the unit in terms of the amount of power it can hold.I will rerun the prices in this table during each significant update to the story.Best Portable Power Stations: Reviews & RecommendationsBest Overall: EcoFlow Delta 2 Laura Lancaster Pros Stronger performer in all testing categories Low weight Easy to use Great value for its power output Cons Not water resistant The compatible EcoFlow solar panels aren’t my favorite Report Card Stated Watt Hours: 1024 Provided 67% of stated watt hour potential at a consistent 34W draw Provided 88% of stated watt hour potential at a consistent 380W draw Provided 83% of stated watt hour potential after 3 months in storage Recharge Time: 1 hour, 15 minutes Confirmed Max Wattage: 1800 watts AC Port and Inverter Power Use: 10 watts IP Rating: IP20 Average Price per Usable Watt Hour: $0.84 Key Features Other Available Sizes: 2048 watt hours, 3600 watt hours Weight: 27 pounds Battery Chemistry: LiFePO4 Manufacturer Claimed Lifecycles to 80 Percent Capacity: 3,000 Warranty: 5 years This one was close.

Power Use: 50 watts IP Rating: IP21 Average Price per Usable Watt Hour: $0.64 Key Features Other Available Sizes: None in this series, but other Oupes models come in different sizes Weight: 27.8 pounds Battery Chemistry: LiFePO4 Manufacturer Claimed Lifecycles to 80 Percent Capacity: 3,500 Warranty: 3 years In my initial round of testing with the Oupes, I was beyond impressed with its performance relative to its price. While it didn’t score stunning marks in my watt hour potential test (60 percent and 76 percent for the low-watt and high-watt draw test, respectively), it costs only 64 cents per watt hour, which is blowing the competition out of the water. It also boasts an impressively fast recharge time of only 43 minutes, one of the quickest I’ve tested.While the AC charging port for the Oupes Mega 1 looks like it would fit a standard AC plug, it won’t. Hold onto the one provided by Oupes. Photo by Laura LancasterOf course, there are always trade-offs with budget products and the Oupes is no exception. Part of the reason the Mega 1 didn’t score as high for efficiency as other options I looked at is because the combined inverter and AC port power use is unusually high. At 50 watts, it’s about three times what other power stations are using. I was also surprised in my high wattage test that the unit stopped supplying power to the AC port with 4 percent still left in the tank. Finally, the warranty isn’t as
