MAXOAK Power Station 500Wh Solar Generator AC50S Wireless Charging Battery Backup for Outdoor Tailgating Camping RV Trip Power Outage(Dual AC Outlet,Pure Sine-Wave,PD 45W USB-C, LED Lighting)…

To start with, I'm a big fan of MAXOAK Power Stations. A couple of years ago I needed a source of power for my CPAP device for a "off the grid" tent camping trip. I found the MAXOAK model K5 CPAP Power Bank on Amazon, boasting more power than most others. It worked great, giving me four good nights before needing recharged. But it was limited to only 12, 15, & 24 volt output and 1 USB port.MAXOAK customer service is top notch and highly responsive. On the K5, I was contacted within 24 hours of my Amazon order about my CPAP device to be sure the proper power cable for my device would be shipped. I was impressed with MAXOAK.All that said, the AC50 is a compact, well designed unit with lots of power and outlets. All the outlets are well identified & on the front, with only the charging port and light bar on the back. I like the rubber door on the 12V /10A outlet. It dresses up the package and maybe keeps little fingers out of it on the picnic table where this unit is ideal. Not sure why the power button is only 'delayed off' as the DC & AC are both 'delayed on & off'. All 3 are double delayed on the model EB40 which I also own. It does have a nice 'auto off' feature in 1 min if the power button is accidently bumped. The LCD screen goes dark in about 30 sec but will come on with the touch of any button. The little green LEDs are really bright in a dark room as I found out on my bed stand. Next time, on the floor at night.The PD45W outlet is not a 5th USB outlet utilizing a type 'C' cable as I found out. It is a Power Delivery (PD) fast charging protocol outlet. This I learned by it not charging my only 'C' cable device. I contacted MAXOAK and they explained the outlet is intended for newer devices that utilizes the PD Protocol. I ended up going to the internet to get smarter on PD protocol. For us "old technology" people, more information in the user manual would helpful.We live in rural east coast South Florida subject to power outages and Hurricanes. With the latter, we typically lose power for 5 to 7 days. The AC50 has plenty of power to get you through with the basic essentials such as a small TV, table lamp, fan etc. Though I have the K5 CPAP Power Bank, I tested my CPAP using the AC outlet which typically is not power efficient. I got two 7+ hour nights at 12-17 pressure and no humidity using 40% battery. With lower pressures and hours, I'm sure 5+ nights are possible. The wireless charging is also a nice feature for all those devices that can use it. I found that my cordless toothbrush will charge on it also.Since we won't be camping again for several months, I will update this review later with that experience.All in all, the AC50 is a nice addition to the MAXOAK family of Power Stations, with lots of power, easy to use and small enough to take anywhere you need portable power. I like it!

I purchased this mainly to charge my phone and run my cpap (Resmed Airsense 10) at night when primitive camping. From a full charge it ran my cpap all night and charged my iphone and only used around 20% of the battery, so it should last 2-3 days easily on a full charge. This was with humidity on (but on a very low setting of 1), and my range is set between 10 and 15 on pressure. I did use the 12v to 24v cigarette lighter adapter so I didn't use the inverter but it worked great. The only comment I would have is that the dc jack for cigarette lighter accessories doesn't seem very deep and my resmed adapter didn't seem to want to stay in it very well. I had a small extension cord on my truck for this type of outlet and it seemed to be far more secure in the outlet and then I plugged my resmed adapter into that and it was a much more secure connection. I would HIGHLY recommend this for anyone looking for an inexpensive battery backup solution for the cpap. I was blown away at how well this worked. I never tried using it a second night without charging as we ran a generator during the day to recharge the batteries in our camper (so we could run out heater and what not) so I went ahead and charged it back up each night.

Earlier this past summer I purchased a CPAP battery backup power supply from Maxoak. Ive used it several times and it has worked perfectly. I use a Resmed Airsense 10 machine. At my perscribed setting this device powered my CPAP for 4 nights - and there eas enough power remaining for probably another 3 or 4 hours. It's more than anyone could ever ask for.Based upon my experience with the first Maxoak I purchased a larger power supply. This new one is more powerful, but also has the added benefit of being able to power my CPAP and other things simultaneously.This power supply ran my CPAP, a fan (for white noise), my property motion sensor device, and a bedside lamp all at 110v.I did this for one night. There is no doubt in my mind that this would run all of those devices for 2 nights. I also ran my woodstove fan for 8 hours the other day - our local electric co-opis notorious for having outages at ALL times during the year.This device is expensive, but for the power it provides and the convenience, well, I'd say it's a bargain.I'm truly glad I purchased it !

Pros:- 4 flashlight settings- input in the back- many output ports (7 to count)- customization of turning the AC and DC on and off- LED screen explaining how much watts input and output there is at the moment - broken down by AC and DC- enormous power amount- sleek and soft style with soft corners- easy to carry handles- easy to plug my dokio solar panel into itCons:- sometimes it doesn't auto-start on the panel I'm using - so I take it to another panel. The battery's so large it needs a massive upstart. When I do get it to jumpstart - it's much lower than before for charging (lower wattage of input).- no exact % battery level - the worst part of this battery- battery doesn't like to be too low to high of an amount (like if it's empty - it's really hard to startup)- the USB-C charger is slower than the other ports- doesn't explain what "W" represents (W - is actually Wh - so 10W means 10W/hour) - 2nd worst part

It's small and relatively light weight, and perfect for my two uses: (1) I have an RV and enjoy boondocking and staying with Harvest Hosts. But with my CPAP, going without power was impossible unless I ran the generator (which we tried once and said, "never again!") Once I got the MAXOAK, problem solved. This holds me easily for two nights, three if I don't run the CPAP humidifier. (2) Seems like most power outages are in the evening or at night ... I don't really care when the power comes back on, but until it does I can't go to sleep without my CPAP. With the MAXOAK, that's no longer an issue. Completely quiet - no fan noise or anything. Expensive but totally worth it. Sure, it has lots of other uses, but running my CPAP was #1 for me.
