300W Portable Power Generator Lithium Portable Power Station 288Wh CPAP Backup Battery Pack Power Source Supply 110V AC Outlet, QC3.0 USB, 12V/24V DC, Solar Generator inverter for Camping Fishing Home

This portable generator works as advertised. I like the on screen digital display that shows how much power is being inputted during charging and from what source, and how much is outputted when a device is plugged into the generator. The display is very informative. I also like its lightweight and easy to carry around in its own carry bag provided by the seller. No other seller that I found on Amazon does that. It is also easy to charge through a regular120v wall outlet, solar panel, or through a car cigarette electrical port. It is also priced better than a Rockpals generator and other similar brands. That is a huge plus for me. Overall, I recommend this generator.

First impressions: the unit is solidly constructed, and it feels substantial but is smaller and lighter than I expected which is great. The display shows useful information and overall it seems to work well. It gets warm (not hot) to the touch and there is an internal cooling fan.In order to test the capacity, I charged it up all the way using the AC cord, then put it a ~10-15W load on it. Unfortunately, it seems the auto-off function kicked in and turned off the power after a short period of time. So if you're looking to run a light load off the 120V inverter, this is not the choice for you.On my second try, I charged it up again, plugged a Kill-A-Watt into the 120V out socket, and plugged in a computer drawing ~50W. The Kill-A-Watt measured 0.22 kWh before the battery shut off. This unit claims >= 85% efficiency, which means the usable battery capacity was 220Wh/0.85 = 259Wh, which is less than 90% of the advertised 288Wh. Or if you look at it another way, if the battery actually has 288Wh, then I only got 76% efficiency out of it which is kind of sad.I also tested to make sure the four USB ports and the 12V cigarette lighter plug work, but did not measure output or battery longevity when using these. It should be more efficient than the 120V since there is no inverter. My phone did seem to charge pretty quickly off the USB port.A couple of misc things about this unit:- The battery can be charged and discharged at the same time, which isn't true of many similar units- This is far bigger than the 160Wh size allowed on airplanes by FAA regulations, so you can't fly with it- The little buttons above the ports that turn on/off the ports seem to turn on a small, dim, internal light somewhere. It doesn't seem like it's a feature, as you can only see a little bit of light leaking through gaps/cracks in the outer shell when you turn on the switches and it doesn't seem to light up anything useful in particular. It's very strange.

The design and craftsmen of it are top notch and I really appreciate the lights. Its weight is in the reasonable range. Recommend it if you are into camping or astronomy in the wild.Just one thing: the carrying handle could have more clearance if you have big hands like mine. It could be too small with heavy gloves on in winter.

Bought this 11/19 and used it 1st time during power outage to run a CPAP and charge cell phones. Performed very well and recharged twice, then stopped taking a charge the 3rd time. Will partially charge, but appears to be draining at the same time and quickly runs out of charge. Presume the li-ion battery failed.

Don’t buy it. Not going to waste my typing skills to explain. It’s not a RockPal. always buy genuine items no clones

So thankful for these little power generators. I have purchased three so far. I like having off-grid power-up of small electronics and LED lights. Who knows, maybe someday I'll live next door to a Sasquatch and need these cool LED panel lights to get a good look at him (or her). Options for 12v plug, USB connects and a 120 A/C outlet cover just about everything I own that draws power. I can watch an old CRT television and DVD player for two guilt-free hours, well almost. I still feel bad wasting time watching TV when there is work to do. The power input option for solar panels is a trouble-free and easy connect to renewable (mostly free) power. I also like the compact build and quiet operation of this portable generator. If you put your ear down next to the thing you can hear the faint noise of a fan running. It's nearly undetectable in a silent room. The gauges provided indicate watts used by small A/C appliances (up to 300 watts). Things I've powered up so far:- Portable power bricks used for charging cell phones on the fly- USB powered, LED lights (5 watt)- USB powered, fan- USB powered, personal heater (250w)- Electric mattress cover/heater (low watt model; replaces area heater in my room)- Handheld Ham Radio- Bluetooth Transmitter- iPod- Kindles 1&2- Rechargeable flashlights- Bluetooth speaker

I purchased this unit to power my CPAP machine on camping trips. It came 3/4 charged, so I discharged it by connecting my CPAP and using it from AC. As expected it only lasted 5 hours with the heated humidity on. It took about 6.5 hours to fully recharge the battery. I switched my CPAP to the DC converter and disabled the humidifier and was able to get 4 nights sleep on the battery. I recharged the battery from the DC connection my my truck and it took 7.5 hours. It's held the 100% charge now for over a week.So far this battery is performing as advertised or better. It's identical to others, but a few dollars less.

Price point is excellent, build quality very good, overall a very good product to have when power outages occur. Charges fast !
