Not all power stations are created equally, and that can be said about any product, but in the case of power stations, you have to look closely and understand what it features and does not feature. Does the power station use LiFePO4 batteries? Does the screen show helpful info? Does the power station have app integration?

Questioning and comparing power stations is vital to get the best one for your needs. In this review, I’m taking a look at this FlashFish 560W portable power station, and I’ve got to be honest, this one isn’t the best choice, but it could be if the price were lowered substantially.

Battery Capacity & Efficiency

The 520Wh battery capacity of this FlashFish power station is decent, and what matters most is the capacity you’re able to use. That is why I ran an AC capacity test using a watt meter to measure the watt hours, and I powered a mini crockpot at high, which had a 90W power output. So I ran the crockpot until the power station was at 0%, and I ended up with a 430Wh capacity that I could pull from the FlashFish power station, which is an 83% efficiency.

An 83% efficiency from a power station is pretty good, as I’ve seen worse from some other power stations having a 70% efficiency, so you can use most of the capacity that this power station says it has.

For 430Wh of usable capacity, you’re looking at a decent runtime, but it all depends on what appliance you want to power from. Considering the 520Wh initial capacity, if you power a 500W appliance, you will get about an hour of usage time. In contrast, a 250W appliance will give you about 2 hours of runtime, and a 100W appliance will get you about five hours of runtime. The battery capacity of this FlashFish power station is good and one of the best parts of this power station.

Output Charging

The port selection of this FlashFish power station is decent; there are four charging ports, two AC outlets, a single cigarette lighter port, and four DC barrel ports. So most of what you can find on similar capacity power stations, but let’s see what each offers.

Charging Ports

The charging ports on this FlashFish power station aren’t breaking any limits and should be more powerful. There are three USB-A ports and a single USB-C Power Delivery port. One of the USB-A ports features Quick Charge, which means that it has an 18W output, two standard USB-A ports share a 15W output, and the USB-C PD port has an 18W output.

The biggest letdown is that the USB-C Power Delivery port has an 18W output, while it should have at least a 60W or higher charge rate because that is what the competition offers. In my testing, I used all the charging ports simultaneously, with a Galaxy Note 9 fast charging from the USB-A Quick Charge port, an LG G7, and a Galaxy A51 standard charging from the two standard USB-A ports.

One surprise I ran into is that the USB-C port could recharge my Lenovo laptop at about 22W. So, even though the specs of the USB-C port say that it’s an 18W port, it’s higher than that. Once again, though, I still think the USB-C port should be more powerful.

I didn’t test out the car cigarette lighter port or the DC barrel ports, but the car port has a 12V/10A output, and the DC ports have a 12V/10A output, too. These ports are most helpful for charging and powering devices that can use these connections.

AC Outlets

There are two three-prong AC outlets on his FlashFish power station, and the overall output of the unit is 560W. For the first test, I wanted to see if this unit could power a Black & Decker min fridge as the power station does have a 1100W peak output through its AC outlets, and the mini fridge has an 800W-900W jump of power, and then it levels out at about 80W when it runs. However, when I turned on the mini fridge, the watt meter jumped to 534W, and then the power station shut down, so it couldn’t handle the jump in power.

For my next test, I powered a Ninja full-sized blender and set the blender to low, medium, and high, and the power station was able to power the blender with no problems. At its highest setting, the power station was outputting 250W, and even with food inside the blender, I’m sure it could still power it.

After the blender test, I powered a Milwaukee battery charger that used about 68W to recharge a battery and an Aukey lamp that used about 20W. With powering the battery charger and the lamp, this FlashFish power station can easily last many hours.


Then for my next test, I powered a large crockpot at high, and that had a 204W power usage, and then I powered a mini crockpot with a 90W power usage; after powering them separately, I powered them at the same time, and they ran perfectly as they should have because power station had about a 295W output when powering the two crockpots simultaneously.

For the final test, I powered a 32-inch Samsung TV, and with no surprise, it ran fine with 48W power usage. Overall, the AC outlets on this power station perform how they’re supposed to; that said, it was still disappointing seeing that it couldn’t power the mini fridge and handle that jump in power from the refrigerator; however, that did let me know that this FlashFish power station has a strict 560W max output and is not able to power anything over it.

Input Charging

The recharging for this FlashFish power station could use some work regarding recharging speed. You can recharge the power station using the included AC charging brick or car charging cable via the DC input port on the unit, or you can recharge it via solar panel with the Anderson port on the power station.

The AC recharging is 90W which is slow for a 520Wh capacity and will get the power station back to full power in about 7 hours, going from 0% to 100%. For the solar recharging, this power station has a 130W solar input, and I used an AlphaESS 200W solar panel to recharge it with and got about 80W solar input via the Andreson port on the power station.

Overall, faster recharging would have been better.

Size and Weight

The size and weight of this FlashFish 520Wh power station are to be expected. It has an 11-inch length, a width of 7 inches, and a height of 6.5 inches. The weight of the power station is 12.5 pounds. You can quickly move it around anywhere, and portability is made more accessible with the handle at the top.

Functional Components

The design quality of this FlashFish power station is severely lacking. The screen is incredibly minimal with the features because the screen does not show the wattage input, output, or an estimated runtime. The screen shows a battery logo with capacity increments but not the battery percentage. So design is way off compared to many other power stations on the market. Most other power stations have a percentage display for their capacity, a wattage input, and output, and some also have an estimated runtime on their screen.

In addition to showing the battery logo, the screen also shows what sections are powered on, such as the USB, DC, or AC outlet sections, as each of these sections has its power button to activate them.

Also, the charging port, DC, and AC outlets are not labeled, meaning they don’t have any indication of what the ports are capable of, such as noting their output.

Structure and Material

The build quality of this FlashFish power station is comparable to other power stations as this one is also made of plastic. The same rules apply here; don’t expose the unit to water or drop; it should hold up just fine.


On the technical level, this FlashFish power station did turn off once it went over the 560W max output, showing that it does have protections to keep it safe and not damaging itself.


This FlashFish power station is reliable enough for a 560W power station, but critical things are missing that you would expect from it. The screen is scarce and does not show vital info that it should; the charging ports are relatively weak, the recharging is slow, and the power station still uses Lithium-Ion batteries, which come at a relatively high price.

Taking the product for what it is, yes, it’s reliable, but comparing it to the competition, then it’s not the most reliable as this unit does not even feature pass-through charging.

The FlashFish 560W power station is a decent unit that should have its price knocked down a peg or two simply because it’s not an up-to-date power station. The screen, recharging, charging ports, and battery type are all areas this unit lacks, as the competition has better features and can offer them at a lower price than this FlashFish unit.
