Aaoyun 300 Watt Portable Power Station Review

I’m a big proponent of portable power stations.  I own several and they are scattered about the house performing various missions.   One problem with these power stations is that they are generally pretty expensive.  Imagine my surprise when Aaoyun provided me their Aaoyun 300 Watt Portable Power Station to review.

At the current Amazon price of $155.99 it is a bargain compared to many other of its competitors.   I’ve been using and abusing this for a couple of weeks now and it has passed through my gauntlet with stellar results.

Key Features

I’m going to start off this discussion with a not so obvious point.  As I stated earlier I own several competitors power stations.  And while they all have a massively bright torch on them, the Aaoyun has a 360 Camping Light which is quite a bit more subdued.  When I set up my tent I always have a power supply AND an additional light.  The Aaoyun has one built right in and man is it PERFECT for tent camping.  And it is one less thing to hump in.  It, by far, is my favorite feature.  It makes a great night light as well for around the house.

UPDATE:  We had an ice storm last night (2/19/2025). We lost power twice for around an hour each time.  The Camping Light was EXACTLY what we needed to light up our bedroom enough to see and function.  Also, the carrying handle was perfect for carrying around the house to check things out.  I cannot say enough about that camping light and the mobility of the Aaoyun portable power supply. 

Additionally, here are some more features:

• Lightweight at just over 7 lbs.
• 296 Wh max capacity
• USB C or Solar Charging
• 3 USB A ports
• 1 USB C port (input or output)
• 12 volt, 10 Amp “cigarette lighter” output port
• 110 volt AC outlet
• Display indicating amount of charge remaining.
• Outdoor torch with SOS flashing
• Carrying strap
• Charging cable and AC brick included
• Pure Sine Wave output (won’t damage sensitive electronics)

Run Time

Obviously 300 watts won’t light up Times Square but it is good for light work.  Over the past couple weeks I have charged iPhones, ham radios,  GoPro batteries, flashlights, etc.  Anything around the house that can be charged, I have been charging it.   A long time ago I made a spreadsheet to calculate run times for various wattages.  Generally when I have 1 to 3 things plugged in it generally pulls about 5 to 10 watts (depending on the items).

Run Time Calculator Aaoyun 300 Watt Portable Power Supply

Naturally, the first thing I did was to test the run time.  Unfortunately, the power station does not indicate consumed wattage.  That would be a cool feature.  But let’s face it, the only thing that benefits is a reviewer like me.  If you are camping or in a grid down situation you’ll be more concerned with remaining capacity.  My estimates of run time are based on knowing the wattage while charging of a few items I own.

My results fell just about perfectly in line with my spreadsheet entries above.  I think it can be surmised though that this will degrade a bit over time.  This will be the case with ANY power station though, as the batteries age.

When using the 110 volt AC outlet the inverter plus what you are operating can consume a full 300 watts.  This means you’ll have significant less run times when using the AC outlet.

Solar Charging

I had a solar cable laying around here and I verified that the Aaoyun has a center pole positive and negative barrel before hooking it up.  Then I hooked it to a 50 watt and then subsequently a 100 watt solar panel.

It worked like a champ.  The only problem I had was staying in the sun in a house surrounded by trees in winter time in North Carolina.

Charging worked as advertised.

The cable I used is a iGreely cable and it should be noted that you need a cable with a 2.5mm adapter which the iGreely comes with.

You should also ensure that your solar panel output voltage is between 5 volts and 24 volts.  Anything greater than 24 volts could cause a failure.  As indicated below the output of my 50 watt panel in the window was just shy of 11 volts.

Recommendations

I already mentioned that I wish it had a display of output wattage while charging.  One more USB C port would be awesome.  Or I would recommend an adapter be provided from USB A to USB C.  These are all small wish list items and written from a REVIEWER perspective and not a tent camping perspective.

Can’t leave this blog entry without a YouTube overview video.

Should You Buy One?

Yes. Yes. A thousand times yes.  I have many portable power stations and for the price this one is a bargain.  The real key though will be product longevity which obviously I can’t explore in the short time I’ve had this.

I swear to you if it didn’t work well or failed you’d have read about it here.  While I was provided this for free to review I was not paid or otherwise incentivized to provide a positive review.  If I hated it, you’d know it.

This is a must for tent campers.  That subdued illumination on the top is a feature I can’t believe anyone else hasn’t added to their station.
