Picowe Portable Power Station 250Wh Rechargeable Lithium Battery Pack Solar Power Generator 110V AC Outlet 3 DC Port 2 USB Ports Emergency Power Supply Backup for CPAP Camping Fishing Travel

Can support up to 250W of continuous output, which covers pretty much all my applications. Enough to power my laptop, phone, and TV for a full day of realistic use without a need to recharge. Can also run my home heating system or the refrigerator for a few hours/day if needed.Comes with adapters to charge it from a wall outlet or a car’s 12-Volt outlet. Can also be charged from a solar panel if you can get the right adapter on your own.Power outages, bring it on!Seems to actually provide a pure sine-wive AC output. I don't have an oscilloscope, but running my stereo from this as the power source produced a clean sound.My only gripe is that the lights that are supposed to represent how much charge is left are way off. I was measuring as I was discharging the battery, and after 120 Watt-hours, it said only 20% were left. After that, the battery had another 90 Watt-hours left. The remaining 40 Watt-hours (it’s rated for a total of 250) was likely due to DC to AC conversion losses and wire resistance.

I opened it once, laid aside for 1 year. Needed for cpap use, never worked again, wish I could return this piece of crap back to seller and Amazon! DON’T purchase this unit, now I am going to have problems returning it! I wish AMAZON would do something about it! If AMAZON could contact me about it, it would be nice

This device is buggy, When you connect a device for power the unit turns on regardless of whether the power button is on or off. When connecting the device to charge, it sometimes does not indicate the level of charge its at unless you unplug it and try again a couple times. I've connected my lower power Dometic fridge that draws a measly .22mah and this thing keeps it going for about 1-2 hours then turns off. Then upon turning on the battery its at around 60% power left so I'm not sure why the unit is turning off... (not over heating, high amp/voltage draws occurred) it just wanted to shut off... Not a big fan, and will be using this to charge my phone's and fan's for now. Should have gotten a Goal Zero Yeti...

This thing is really cool and compact. I like it for what it is.Though I am a bit sad that it didn't work as I wanted it to 😥I was hoping to use this as a pass through connection. I am a truck driver and I was planning on having my electronics hooked to this generator while having the generator hooked to the truck. Why? So that when I turn the truck off, my electronics would use this battery pack instead of my trucks battery.😩 It's a cool thing to have, but I'm wondering if I actually need it now 🤷‍♂️

Unit functions as advertised, I've been running a 110 volt 19" flat screen LED TV and a Super Nintendo clone powered from USB for over an hour and a half and I still show 75% charge. However I would like the ability to charge the unit while it is switched on, and that function doesn't exist. While using the 110v power, if I plug in a charger the 110v power shuts itself off. The 12v output still functions, in fact, it's even on when the switch is in the OFF position.

I bought this unit primarily to run a CPAP overnight in the event of a power outage. I have run this unit through 2 cycles without problems. A cycle consisted of powering my CPAP overnight for 2 nights in a row then recharging. I doubt (and did not try) that I could get another full-night's use. (If I had wanted a third night I would have opted for the next size up (300Wh) along with the extra cost. The last 3 hurricanes in this area resulted on no more than a 3.5hr outage, so I figure I have made the correct choice.) Recharging time seemed to be as stated. I did not feel any excess heat generated either during use or recharging. I did not give a "durability" rating since I do not believe 4 night's use gives me enough experience in this area.

This thing must be 90% lithium battery packed.It all works as advertised, and is handy as all get out for sooo many situations.I give it 6 stars for just being SOLID.4 stars because I have no idea how long it will last yet.

The 12 volt plugs and charger are missing from this amazon backed product. How do I acquire these plugs?This is my second unit to backup the first. When I can charge the unit it runs my video equipment well.
