These pricey [url=https://www.jkchinasourcing.com/]battery-
powered device[/url]s are the only type of generator that can be used
indoors safely
Since generators emit carbon monoxide, they require that you take
critical safety measures, including running the device outside, at
least 20 feet away from any structure.
But in an age when we can charge our smartphones with a battery pack
that fits inside a pants pocket, shouldn't there be a simpler way
to restore power in the wake of a storm? Or, say, power a campsite
without the constant hum of a gas-fueled generator?
Such is the promise of [url=https://www.jkchinasourcing.com/]portable
power station[/url]s, also known as battery-powered inverter
generators. Essentially, they're oversized rechargeable batteries
—about the size of a countertop microwave oven—that you plug into a
typical 110-volt outlet to top off.
When duty calls, you can safely run a portable power station inside,
since it doesn't generate any emissions. They have enough
capacity to power a few small appliances for a short time. With a
host of different outlets (standard 120v outlets, USB ports, and DC
chargers), you can use the station to charge electronics, too. And
the units often come with portable solar panels, to add more charging
capabilities and extend runtime.
“These generators have no fumes and all of the models we tested made
virtually no noise,” says test engineer Dave Trezza, who oversees
generator testing at Consumer Reports. “But, if these power stations
go dead and you’re unable to use your solar panels, you can’t
recharge them. You can’t just use another gallon of gas.”
We see models from brands, including Goal Zero, Humless, K2, and
Kohler in our portable power station ratings. Some companies, like
Goal Zero, market these portable power stations as perfect for
apartment preparedness during storms (as opposed to single-family
homes with a yard that can accommodate a generator).
How We Test Portable Power Stations
In our labs, CR test engineers evaluate five key measures to rate
portable [url=http://www.jkchinasourcing.com/outdoor-power-station/]
outdoor power station[/url]s: runtime, power delivery, power quality,
ease of use, and noise.
To test runtime, we run a constant 300-watt load to simulate powering
a TV and a few lights. We also hook each battery up to a side-by-side
refrigerator to see how long it lasts. The best model in our tests
powered the fridge for 44 hours on one charge (the worst only managed
for 13 hours). For power delivery, or how well a model can maintain
voltage when tasked with different loads, we use a variety of
devices, including a 1?2-horsepower submersible pump and a 10,000-BTU
air conditioners.
We also judge noise output and found that, as a category, these
batteries run quietly: All the models we tested earned an Excellent
score for noise.
Below, our experts share some pros and cons on using
[url=https://www.jkchinasourcing.com/]portable power station[/url]s.
See how the most popular models fared in our ratings, and check our
generator buying guide to compare portable power stations to other
types of generators.
1. They Can’t Deliver Nearly as Much Power as Gas Generators
As with their gasoline-fueled counterparts, portable power stations
require a transfer switch should you wish to
[url=http://www.jkchinasourcing.com/power-bank/]power bank[/url]
things such as your furnace, overhead lights, or any thing else in
your home that’s hardwired.
But while a recreational inverter generator would probably keep the
TV and a few lights on for 8 to 13 hours on one tank of gas,
you'd see anywhere from 3 to 9 hours of power, under the same
circumstances, with a portable power station.
And you won't be able to run, for instance, your power-guzzling
well pump.
2. They Take Awhile to Charge
In our tests, most of these models require hours of charging
(typically overnight) to provide you with a full battery and max
runtime.
So—assuming you fully charged the battery before a predicted weather
event—a portable power [url=http://www.jkchinasourcing.com/beauty-
device/]beauty device[/url] station could give you hours of
electricity to run a refrigerator or another essential appliance.
But Trezza notes that once the battery is dead, if you’re without
power and minimal sun, there’s no way to recharge.
3. Charging With Solar Panels Can Be Iffy and Lengthy
If you're dealing with an outage or you're otherwise off the
grid, charging the power station via solar panels is your only option
—and that's provided you have good sun and no obstructions.
In our tests, we found that the solar panels can add to the runtime,
but that might only amount to an extra hour or two of power
with larger appliances.
4. They’re Not All That Portable
Portable power stations are about the size of an average microwave
oven, but they're fairly heavy—most in our tests weigh more than
80 pounds.
That means you'll likely need an extra pair of hands to lift one
into the trunk of your car. Some of the models come with wheels, but
not all wheels are large in size, which makes rolling them across a
lawn difficult.
5. They Don’t Come Cheap
The portable power stations we tested cost between $1,500 and $3,500.
And our best portable gas generator costs less than the worst
portable power station.
Before buying one of these power stations, consider if you might be
better served by a portable generator. In the event of a outage, you
can continue to add fuel, and portable generators typically provide
enough power to keep larger appliances running. Check out our buying
guide on generators to learn which type might best suit your needs.
