When the power goes out or you are visiting the great outdoors with gadgets in tow, you might carry a portable power station, and it might be the most advanced one yet. The 1500W of power and 1229Wh of capacity from a LiFePO4 battery, which it promises is faster to charge, longer-lasting, and might even be safer than the lithium-ion battery packs, is offered by the new Anker 757 Powerhouse.

LiFePO4 batteries are not new in the battery space. They are in some electric cars because they don't need to be replaced as often and because they don't turn into a raging fire when damaged in an accident. Most consumer electronics don't use them because they're too heavy. The 1000Wh Jackery power station has around 20 percent more capacity than the 757, but it weighs almost twice as much. Jackery has a power station that weighs less.

The ability to charge to 80 percent in just an hour off the wall and upwards of 3,000 battery charge cycles are just some of the benefits of LiFePO4 for power stations.

The Bluetti appears to have more outputs than the other products, with six three-prong AC outlets and a pair of wireless charging pads up top. The others top out at 60WPD, which the Anker has, but it can deliver a full 100W of USB-C charging to a powerful laptop, as well as three three-prong outlets and four two-prong outlets.

The 300 watt triple-solar-panel array that Anker will be selling for an undisclosed price will allow it to charge its battery from the sun in 3.6 hours. The Bluetti can charge in under three hours from 700W worth of panels, and CTECHi says it can charge from a set of 500W panels in nine hours.

The other notable difference is that Anker is offering a 5-year warranty on its battery, quite a bit longer than the two years the other companies offer, and it claims its battery should still charge up to 100 percent capacity. If you leave it sitting for a year after a charge, it should have 62 percent capacity remaining.

It has a nifty light bar, I suppose. If you are trying to plug things in when it is dark, it might be useful.
