They're never cheap, but having one for emergencies is highly recommended so you can charge and power all your critical devices when you need to. Given the high prices, however, you typically want to wait for a good deal before picking one up. On Amazon, the EcoFlow DELTA 3 Max is available now for just $1,148.99, saving you $570. This is a powerful battery that comes with solar panels that let you top it off anytime it's sunny. EcoFlow DELTA 3 Max Brand EcoFlow Dimensions 19.5 × 9.4 × 12 in Weight 44.7 lbs (20.3 kg) AC Output ports 4 Solar input rating Up to 500W USB Ports 3 USB-C; 1 USB-A The EcoFlow DELTA 3 Max is a 2,048Wh LiFePO4 portable power station with a built-in UPS function that switches over in under 10ms. It outputs 2,400W of AC power, or up to 3,400W in X-Boost mode, and recharges from 0 to 80% in about 1.13 hours. Battery type LiFePO4 (LFP) You're getting a lot of power for your money A big battery with serious output Credit: EcoFlow The standout spec for the DELTA 3 Max is its 2048Wh rated capacity (51.2V, 40Ah), built on LFP (LiFePO4) cells. On the output side, you get 2400W of rated AC output across four outlets, each rated for up to 20A, so you can run several devices at once. Essentially, the EcoFlow DELTA 3 Max is meant for times when you don't have easy access to power, whether it's because you're out on a campsite or you've lost power at home. As such, the solar panels are a serious boon to this station. The solar input of the DELTA 3 Max accepts up to 500W (11-60V, 13A), so you can pair it with solar panels for camping or as a backup when the power goes out. For smaller gear, you get a single USB-C port with up to 100W of output and a 12V DC output rated for 126W total. The listing puts noise at 25dB or less at 600W, which helps if it's running near where you sleep or work. The main drawback is size. At 44.8 lbs (20.3kg) and 19.4 x 9.4 x 12 inches, it's something you'll only carry between the car and the campsite or garage. It's certainly portable, but not "slip in your bag and carry it everywhere" portable. The EcoFlow DELTA 3 Max is built to efficiently charge several devices at once, so if you only want something to charge your phone, you'll want to look elsewhere. Portable power stations aren't cheap, so it's best to take advantage of a sale like this when you see it. Grab the EcoFlow DELTA 3 Max on Amazon while it's still on sale.
