Anker 757 PowerHouse provides high-power, portable backup power
Anker has long provided battery backup solutions for portable electronics and has eventually moved on to larger power-station products. The Anker 757 PowerHouse 1500W power station represents their largest product yet. With fast charging and plenty of connectivity options, can this device power your next long-distance outing?
Portable and durable Anker 757 PowerHouse
The Anker 757 PowerHouse has one of the most elegant designs we've seen in a powerhouse. All controls and outlets are located on the front of the unit. You also get a nifty LED strip light on top that emits enough light to let you see around the campsite—even a job site table to read building plans.
The 757 PowerHouse Power Station has convenient handles neatly arranged to deadlift this giant battery. The only problem is that you can only lift it hard, as there are no wheels to help you move this 44-pound device from one place to another.
Large capacity and high power
However, all that weight means important things. The appearance of Anker 757 Power Station does not reach the rated power of 1500W. It also has a battery capacity of 1,229Wh. While not the largest power center we've tested or seen, it still represents a lot of stored energy.
Internally, Anker appears to have built the Powerhouse 757 to handle being run over by a truck. It has an aluminum frame surrounding the electronics and 1229Wh worth of LFP (LiFePO4) batteries.
Several large radiators manage the heat associated with storing and offloading all potential power.
It claims to deliver an impressive 1,500W of output power and 2,400W of surge capability for aggressive start-ups. Anker also claims that the device can handle the following tasks:
|To charge the phone||10Wh||97X|
|led light||12W||82 hours|
|Charge the drone||40Wh||24.5 times|
|portable refrigerator||45W||22 hours|
|LCD TV||110W||9 hours|
|Coffee machine||1000W||1 hour|
|electric oven||1150W||48 minutes|
|Wired Recipe Saw*||1200W||48 minutes|
|cord cutter||1200W||48 minutes|
|Electric Chainsaw*||1440W||36 minutes|
|Demo Hammer*||1500W||36 minutes|
real world test
We hooked up a 15A DeWalt shop vac to an Anker 757. It consumed about 1200 watts and ran for 54 minutes and 43 seconds. According to estimates given by Anker, this is actually 14% higher than their numbers. We'll consider it a win.
When testing with tools below 1500W, Anker provided enough power to keep them running. As a temporary power source for medium-sized tools, you should be able to get some use out of this product. However, the higher the load, the less runtime you receive.
On a whim, we decided to test the Anker 757 with a more power-hungry tool, the Milwaukee 15A Super SawZall. This might be the best corded reciprocating saw on the planet – if not the most popular. Realize that the maximum power of the tool is about 1800 watts – well beyond the power station's stated capabilities . Even so, the Anker PowerHouse 757 got me down about 3.5 times before shutting off power to the outlet! After a cool down period of about 30 seconds, it let me turn the socket back on and make another 3-4 cuts before turning it off again. We suspect high current draw to be the culprit. Impress us anyway.
Anker designed the PowerHouse 757 for less aggressive loads and longer runtimes. Not surprising given its design. Even a continuous 12A tool draw (1440W) puts a very aggressive current load on the battery powered system. A battery backup system designed primarily for the jobsite will also feature more protection and portability – maybe even a roll cage.
That doesn't undercut Anker in our opinion — it's just setting it up as a power source designed for camping, camping, UPS capabilities, and putting all that excellent battery storage into applications for which it's more designed.
Charge the power station
It only takes about 1.5 hours to charge with a 20A 120V socket. During the charging process, we felt that the Anker 757 could not be charged within the specified time. On the LCD display, it keeps saying it's approaching 66% charge capacity after almost 90 minutes. After a moment, the LCD shows 100% and the device stops charging. It's not a great user experience, but it charges in the time Anker claims is a full charge. Presumably, if you stop it early and then check the battery level, you should get a fairly accurate number – just not when actually charging the station.
Anker PowerHouse 757 Connectivity
For camping or anything else you can think of, the Anker 757 Charging Station includes 13 ports for connecting all your various devices.
Here's how it breaks down:
- 3 polarized 120VAC outlets
- 3 grounded 120VAC outlets
- 2 x USB-C (100W max) ports
- 4 x USB-A (maximum 12W each) ports
- 12V (120W max) car socket
On the back of the unit, you'll find a 120VAC charging input, a car or solar panel input connection, and a reset button.
Pure sine wave output
Anker not only offers a powerful battery backup system, but also builds it as an uninterruptible power supply (UPS) with 20 millisecond switchover times. It also provides pure sine wave output on six 120VAC outlets, so sensitive electronics get clean power. You may not care about this, but cheap UPS systems without a sine wave output can end up damaging things like refrigerators and some medical equipment.
For such a large powerhouse, the Anker 757 PowerHouse charges fairly quickly. We hooked it up to a 20A circuit and the PowerHouse 757 reached 100% in an hour and thirty-two minutes. While we'd like to see if it hits 80% in an hour as claimed, the truth is, the LCD display is wildly inaccurate while charging. Just before the device reached 100%, the meter showed 1.8 hours at a charge rate of ~300W for a 61% completion. After 10 seconds it reaches 100% and stops charging.
So while we like the speed of the charging process — and Anker does charge as fast as it claims — you won't really know how it's working until you interrupt the charging process and check the display. When charging from an outlet, we recommend waiting at least 1 hour to 90 minutes (if you have enough time) before using it again.
Of course, you can connect up to 300W of solar panels to the 757 if you want to go completely off grid. Doing this, you can charge the Anker 757 to 80% capacity in less than 4 hours.
- 50,000-hour electronics life expectancy
- 6.1″ LCD display
- 5-year limited warranty (excludes solar panels)
