Anker’s largest battery pack ever is a 43-pound powerplant with impressive specs

When the power goes out or you’re exploring the great outdoors with gadgets in tow, you might have a portable power station with you — and Anker may have just released the most advanced yet. The new $1,400 Anker 757 Powerhouse offers 1,500 W of power and 1,229 Wh of capacity from a lithium iron phosphate (LiFePO4) battery, promising to charge faster, last longer, and may even be safer than the lithium-ion batteries you’ll find. can usually be found on the market.

LiFePO4 batteries are nothing new in the battery space. You find them in some electric cars because they don’t need to be replaced as often and because they don’t turn into a raging inferno when hundreds or thousands are badly damaged in an accident. The downside is the weight: most consumer electronics don’t use them because they are much heavier than lithium-ion of the same capacity. The Anker 757 Powerhouse weighs 43.8 pounds, almost twice as much as a 1000Wh Jackery powerhouse, but with only about 20 percent more capacity. Jackery has a 1500 Wh power station that also weighs less.

But we’re starting to see some big, beefy powerhouses embracing LiFePO4 for its benefits, including more than 3,000 battery charge cycles and the ability to charge to 80 percent off the wall in just an hour — things Anker’s 757, the Bluetti AC200P, and the crowdfunded CTECHi ST2000 all boasted.

Mind you, those rival products are even bigger and heavier and more powerful at 2000W and 2000Wh capacity, and the Bluetti seems to have more outlets too – including six three-prong AC outlets and a pair of wireless charging pads until you leave. phone rest. But Anker’s can deliver a full 100W USB-C PD charge to a powerful laptop (the others reach a maximum PD of 60W, which the Anker also has), as well as three three-prong outlets, three two-prong outlets, four USB-A ports of 12 W each and a port for a car lighter.

Anker suggests his battery may also be able to charge faster from the sun than most — it can get to 80 percent in just 3.6 hours with a 300W, triple solar array. Anker will be selling for an undisclosed price soon. TechRadar writes that the Bluetti can technically charge in less than three hours from 700W of panels, and CTECHi says the battery takes nine hours to fully charge from a set of 500W of panels, although with both solar power and a plug can combine if you need faster on.

The other notable difference is that Anker offers a 5-year warranty on the battery, quite a bit longer than the two years other companies offer, and it claims the battery should still charge to 100 percent capacity — not the typical 80 percent — after 3,000 charge cycles. And Anker says if you leave it for a year after a charge, it should still have 62 percent capacity.

Oh, and it has a handy light bar, I think. This can be useful if you’re trying to plug things in after dark.
