When my household went to Maine this summer time, the cottage we stayed in has occasional energy outages and, even when energy is on, it is darkish and has few shops to plug in our gadgets. So, I took the chance to pack the 1229Wh Anker 757 PowerHouse ($1,399.99, on sale now for $1,249.99) to supply working shops for lights and the coffee maker and charging ports for our telephones and laptops.

The 757 PowerHouse is an influence station, a kind of generator that runs on batteries as an alternative of gasoline and is secure to make use of and retailer indoors. Not like most different energy stations, which use lithium-ion or lithium NCM batteries, the 757 PowerHouse makes use of lithium iron phosphate (LFP) batteries. LFP batteries have six occasions as many cost cycles as different lithium-based batteries, giving the 757 PowerHouse an extra-long lifespan of 10 years.

Whereas I could not assess the battery’s lifespan, I spent greater than per week testing the facility and recharging capabilities of the 757 PowerHouse. I discovered it to be a horny, well-built product that could be a nice selection for emergency backup energy. Anker’s LFP product is noticeably bigger and heavier than equally specced lithium-battery-based energy stations, however the further charging cycles are greater than a good tradeoff.

Nonetheless, it is larger and heavier than related capability lithium-ion or Lithium NCM energy stations at 18.2 by 11.3 by 9.3 inches and 43.9 kilos, simply barely transportable for me.

The 757 PowerHouse has loads of charging ports and shops. There are six USB ports – one 100-watt USB-C, one 60-watt USB-C, and 4 12-watt USB-A – that are stacked in a tower. I might like them spaced out a little bit extra, but it surely’s tremendous. The actual downside is with the six AC shops. They’re packed so tightly collectively that almost all energy adapters will cowl up the adjoining shops. Additionally, solely three of the shops are the three-prong grounded selection. So, chances are you’ll have to spend money on adapters to make all the pieces match. There may be additionally a DC automotive charger port. In whole, you possibly can cost as much as 13 gadgets concurrently.

A big 5-inch show on the entrance makes it simple to see how a lot energy you have got left, what number of watts you are at present utilizing, which ports are energetic, your charging mode, and extra.

On the prime of the entrance panel is an LED mild with three mild ranges. Typically the sunshine on these energy stations is a vibrant white, however Anker selected a heat white, which would not be misplaced close to a campfire.

On the again, you will discover the inputs for charging. You’ll be able to cost by way of an everyday AC outlet, your automotive’s DC charger port, or photo voltaic panels (as much as three). Cables for all strategies of charging come within the field.

The 757 PowerHouse doesn’t have an IP score for water and dirt resistance. Subsequently, I’d not suggest utilizing it outside in locations the place it is going to be uncovered to rain and dust or sand.


Utilizing the Anker 757 PowerHouse is straightforward. For USB charging, you plug in your gadget, and it begins charging. The AC shops and the DC car-charger port have energy buttons it is advisable to activate earlier than they work. The AC and DC shops will slowly drain the battery if they’re on, however you possibly can activate Energy Saving mode, which is able to flip off the facility station as soon as your gadgets are totally charged.

You should use the 757 PowerHouse as an uninterruptible energy provide (UPS) along with utilizing it as your major energy supply. To make use of it as a UPS, preserve the 757 PowerHouse linked to an AC outlet and your tools plugged into the 757 PowerHouse. Then, if the facility goes out, the facility station will instantly begin offering energy from its battery.


Just a few energy stations are able to super-fast charging, together with the Anker 757 PowerHouse. It takes simply an hour and a half to totally recharge from a normal AC outlet and an hour to cost to 80 p.c. That is as a result of the 757 PowerHouse can settle for a 1,000-watt enter, one of many highest available on the market. A single photo voltaic panel (100 watts) or a automotive charger (120 watts) will take considerably longer.

Anker claims 3,000 charging cycles and estimates the product will final ten years. Compared, the utmost variety of cycles for lithium-ion-based energy stations is normally round 500 cycles, with a most of about 1,000 cycles. Whereas I could not check the lifespan, the LFP battery know-how is broadly recognized to have the ability to attain the cost cycles that Anker claims.
