At CES: Home Battery Storage Stands Out

January 9, 2023

As battery prices plummet, and mega-factories sprout all over the globe to produce them, home energy storage comes into it’s own. I have a small (briefcase size) device that I carry around the house to keep phone and devices charged. Much bigger systems on the way.

Techcrunch:

As we were roaming the halls of CES in Las Vegas, one product category stood out across the board: There’s a lot of focus on portable (and less portable) power storage. These are more than your average charge-your-phone-once-or-twice battery packs, ranging from simple small power packs to sophisticated power stations that can connect to portable or rooftop solar. The biggest versions can power your whole home for weeks at the time.

The smallest portable power stations usually come with a few 110V sockets and some USB sockets with maybe a 12V car cigarette lighter port for small peripherals. From there, it can get pretty advanced: solid-state batteries, 240V power, wireless charging ports, the ability to plug in additional batteries and the option to be powered from a number of power sources, including mains power, solar, car chargers and even the high-end rapid chargers designed for electric vehicles.

It would be a complete fool’s errand to try to capture everything we saw at CES, but here are a few of the highlights:

Zendure’s Superbase V (pic above) really stretches the definition of what can be considered “portable.” Clocking in at a hefty 100 lbs (46 kg), at least it has a pull-out handle and motorized wheels to help you move it around. Once it’s in position, however, it can do just about everything — it has 6.4 kWh built in. However, it also supports additional battery modules, for a maximum of 64 kWh worth of storage available. Fully loaded out, that’s more than an entry-level Tesla Model 3 battery pack, and the company claims that’s enough to power a typical household for a week.

Packing both 120V and 240V voltage, it can power both small appliances like a fridge and larger home goods like induction cooktops and electric clothes dryers. Hell, with up to 12,000 W of power, you can charge two electric cars with it at the same time, should you need to. The price starts at $3,100. Fully maxed out with four external batteries, you’re looking at a price tag north of $15,000.

EcoFlow came out of nowhere a few years ago and has established itself as a very serious player in the portable power space. At CES, the company launched a battery-powered fridge with ice maker, a portable, an updated version of its battery-powered air conditioning unit and a number of other innovations. The biggest news this year, however, is that it is rolling out systems for full-house battery backup systems later this year.

The biggest news from Bluetti was its full-house power in the form of the B300S and matching inverter series. In normal use, the mains power (or a solar array) keeps the batteries topped up. When the power goes out, the battery packs jump in, like an uninterruptible power supply for your whole house. You can either keep power to everything, or design two separate circuits; one with essential power circuits (your fridge, cooking and heating/cooling, for example), and one with less essential circuits (say, your washing machine and EV).

Geneverse has broad distribution in the U.S., being available at Walmart, Home Depot, Lowe’s, Costco, Sam’s Club and online. It’s easy to see why: The company launched two new power stations. The HomePower One has 1,210 Wh of capacity, 1,200 W of rated power and 2,400 W of surge power, while its bigger brother, the HomePower Two packs 2,419 Wh of capacity, 2,200 W of rated power and 4,400 W of surge power. Both have three 120V outlets, two 100 W USB-C outputs and two USB-A quick-charge sockets.

None of these stats really move the needle — but the price point does. The smaller power station costs $1,500 and the bigger one is $2,500. You can add two or four solar panels to the power stations, respectively, bringing the price tag to $2,600 or $4,800. With prices like that, at-home backup power is starting to come into range for most home owners. The company didn’t skimp on the batteries either, opting for the ultra-high efficiency LFP/ LiFePO4 (lithium iron phosphate) battery tech. These are very safe indeed and provide a lifespan of around 3,000 charge cycles.
