Bluetti AC70
Higher ratedRanked #1 in Best Portable Power Stations
Bluetti AC70
5 sources$359as of Aug 1

768Wh of LiFePO4 behind a 1000W pure sine inverter, in a 22.5 lb box that recharges in about an hour and a half. TechRadar rates the Bluetti AC70 4 out of 5, mostly for the app and the restrained design, while The Power Pick's 4.4 out of 5 leans on charging speed. Power Lifting Mode stretches output to 2000W for resistive loads only. Two AC outlets, no expansion battery and no IP rating are the limits to plan around.

Strengths
  • Smart and subtle design that's suitable for home and vehicle use
  • Excellent companion app for greater control and monitoring
  • 5-year warranty offers strong long-term protection
Watch-outs
  • Only two AC outlets for 768Wh of capacity
  • No expansion battery, so capacity is fixed permanently
  • No IP rating, which keeps it indoors or in a vehicle
EcoFlow Delta 3 Plus
Ranked #4 in Best Portable Power Stations
EcoFlow Delta 3 Plus
6 sources$1,099as of Aug 1

The EcoFlow Delta 3 Plus is a 1024Wh LiFePO4 station whose case rests on output and charging speed: 2400W continuous with a 4800W surge, and a full recharge in about 56 minutes. Trusted Reviews scored it 5 out of 5 and called it a brilliant choice for home backup or camping, and Output Report's 9.1 out of 10 makes the same argument about continuous output being the highest in its capacity class. It costs several hundred dollars more than comparable 1000Wh units, weighs 28 lb, and its fans are plainly audible while charging. Right for people who need high output and plan to expand, wrong for anyone optimising for weight or price.

Strengths
  • 2400W continuous output allows operation of high-wattage appliances like space heaters and induction cooktops
  • 56-minute full charge time via X-Stream technology enables quick recovery during short breaks
  • Expandable up to 5120Wh with additional battery packs for future capacity growth
Watch-outs
  • Costs several hundred dollars more than comparable 1000Wh units from Anker and Jackery
  • At 28 lb it is among the heaviest stations in its capacity class, and there is no wheeled option
  • Fans cycle audibly during fast charging and under heavy load

How they stack up

Bluetti AC70

The Bluetti AC70 offers a smart design and excellent app integration, features that the Anker Solix C1000 and EcoFlow Delta 3 Plus lack. While the EcoFlow River 2 Pro is more portable and the Jackery Solar Generator Kit 2000 offers better solar compatibility, the Bluetti AC70 provides a 5-year warranty and multiple output options, making it ideal for home and vehicle use. However, its 1000W output is insufficient for high-wattage appliances compared to the EcoFlow Delta 3 Plus and lacks weather protection unlike the Jackery model.

EcoFlow Delta 3 Plus

The EcoFlow Delta 3 Plus excels in high-output performance and expandability, features that the Anker Solix C1000 and Bluetti AC70 lack. While the Bluetti AC70 offers a more compact design and better warranty, the Delta 3 Plus provides 2400W continuous output and can scale up to 5120Wh, making it superior for powering high-wattage appliances like induction cooktops. However, its weight and fan noise make it less ideal compared to the lighter and quieter EcoFlow River 2 Pro.
