MAXOAK Portable Power Station EB150 1500Wh AC110V/1000W Camping Solar Generator Lithium Emergency Battery Backup with 2 AC outlet Pure Sinewave,DC12V,USB-C for Outdoor Road Trip Travel Fishing

The product is working very well with quality built. I fully charged the unit and plugged in a box fan and let it ran all night the first day I got it. I like how the LCD displays the watts usage. I also saw in the specifications that the Bluetti uses the LG lithium-ion batteries. Based on my experience dealing with batteries, LG lithium-ion batteries are quite good in general. Since the manufacturer uses good quality batteries, I hope that the rest of the crucial components such as the charge controller, BMS, and inverter, etc. would be in the same high quality.I intend to use this generator as my backup power source. So did a small experiment by connecting a few appliances that I would use on a daily basis to the unit. These are a laptop, and a desk top computer with an external monitor, a modem, and an LED desk lamp. The A/C wattage showed about 113 to 148. Both computers were set to turn off monitors in three minutes and go to sleep in five minutes. I was connecting to the generator all day. I used the computers like I usually do (on and off) and by the end of the day, the battery bar still show 4 bars (out of five) . At this rate and based on my usage, this unit should be able to supply the power for me for the next few days.I really like this generator so far. However, I found a few minor things that I'd like to mention;1] The 42 volt-A/C charger (that accompanied the product) got really hot when I plugged into the unit and started charging. I measured the surface temperature of the charger with a thermometer and it showed 117° F. I don't think that was supposed to be normal. When I noticed that it started to get very hot (almost to the point that I couldn't touch it), I reoriented the charger by standing it up on its side (so the heat can dissipate faster). I also inserted a rack that I borrowed from my toaster oven and raise the charger about an inch from the table (hence increasing air flow). This seemed to work because after a few minutes, I could touch the charging unit again without burning my hand. With that arrangements (the ambient temperature was 69° F at the time), I was able to complete the charge which took about 4 hours (the charger light turned from red to green and the fan on the unit turned off). The charger cooled down after the charging was done. I was surprised because I thought it was going to take at least 8 hours with that 160-watt charger to fully charge the unit. It appeared that the unit had some charge in them which should be fine.Looking back...I should have stopped charging the unit the very minute that I noticed that kind of excessive heat on the charger and contact the seller. I've contacted the seller (who called herself "cimy") this morning and I will update this post later once I heard from the seller.I will try charging the unit with a 300 watt, 24 volt, with 9.78 amp solar panel (within the input specifications) later. I will update this comment.(10/27/2019 - Today, I charged this unit with a 24 volt, 300 watt solar panel (Renogy). The unit showed that it took in between 180-260 watts. The charging was successful without any issue.)2] There is no dust cap for the 12 Volt cigarette lighter socket. It would be nice to protect this outlet from dust and other stuffs while not in use. Fortunately, the diameter of the socket is 2.2 centimeters and I should be able to get it easily either on Amazon or from most auto parts shops (I didn't have a caliper lying around so I used my daughter's ruler...I could be off by a millimeter or so)...... The rest of the comments have to do with the user manual....3] The manual could use some revision. For example, the LCD display for A/C output power is also used for displaying the inverter frequency (either 50Hz or 60Hz) and not just only displaying the wattage for the A/C output. I am mentioning this issue is because of the next item.4] I could not check (or change) the frequency while the unit was still connected to the A/C charger. In order to check and/or change the frequency, you must unplug the A/C charger from unit. The manual does not specifically tell you this. It took me a while to figure this out. By the way, the unit that I got had already been set at 60 Hz so I didn't have to do anything further.5] A picture showing what the screen should look like when selecting frequency would be nice.6] There is no warning when charging with solar panel(s). I was fortunate that I usually read the entire manual before operating anything that comes with one. For this particular case, in the specifications section. I found that the maximum power that can be input to the unit is 500W, the maximum current is 10A, and the voltage must be between 16-60 Vdc. Again, a warning, in the right place, would be nice since this kind of user mistake could damage the unit.7] The manual is slightly unclear in terms of long term storage of the unit. If you look at the "Storage and maintenance" page "EN-02" item 3 and 4. These are for storing the product. Both indicate that the product must be fully charged. However, item 3 says that I should charge the product one a month while item 4 tells me to charge it once every 3 months.8] The A/C output, measured at the outlet on the unit, is 110 and not 120 volts as indicated in the product name and description (as of 10/24/2019). However, the labels on the A/C outlets of this product were correct (the labels said 110 volts). I just reported to Amazon so they can correct the product description. I hope they corrected the information on or after today (10/24/2019).Conclusion: I like the product very much (except for the A/C charger). I will give this five stars for now since the unit (after charging) has been working really well and this is the second day. I will see if their customer service can help me with the charger issue. I will update the rating and this comment after that.(10/30/2019 - Got the replacement A/C charger and it worked without any issue. I am very pleased with their customer service. )

I got my EB150 a week ago and I've been testing it. So far it works great.I've slept with it charging my Philips Dreamstation (without humidifier) for 7 nights, plus a few naps. Also, I've charged my Samsung tablet twice. It's hard to tell with a 5-segment battery indicator, but I think it was down to around 50%.The average draw with the CPAP is 12 watts. The tablet ran at about 17 W. A back of the envelope calculation makes that 788 watts total, a tad over 50%. So that confirms my guess that it was down about halfway. This is pretty good. Plenty left for phones, a small fan, etc.We live in Hurricane country, so having electric power backup is very comforting. In our small townhome, even one of those little Honda generators (which are awesome) wouldn't work. There's no place I'd want to keep it, plus a gasoline can. The Bluetti can be kept anywhere..When severe weather threatens, I can keep the EB150 plugged in to shore power, and keep the CPAP plugged into it. Kind of like an uninterrupted power supply. It can be charged while in use, so what I'm suggesting is possible. (Some batteries, like my Anker Powerhouse, don't have pass-through charging.) it might affect battery longevity to leave it on charge all the time, so I don't recommend this as a standard practice. (See below.)I'm a ham radio operator and I've tested a lot of ways to maintain power for comms etc. in emergency situations. I'm recommending this unit to my friends in the ham community.Some people will point out that there is a limit of 1000 Watts draw on the inverter. You can't run a Skil saw for instance. So be aware of the limitations. For my purposes, this unit meets all my requirements. I don't want to run a microwave with it.The build is very sturdy.Maxoak responded quickly to a question I had.I'd like to thank Maxoak for a superior and well-made product.********* Edited to Add **********After another week of trial runs, here's the latest. I started using it with the CPAP plus humidifier. Every three nights takes it down 2 bars on the battery graphic.. Each bar equals 20%. Once the water in the humidifier warms up, power consumption drops way down. This only takes 5-10 minutes. So I could use it for a week and still have some left over. If we're without power that long, we're bugging out anyway, so I don't need more than that.I put the AC adapter on a smart plug, so it's not charging all the time but I don't have to plug and unplug it all the time. 3 hours on the charger brings it up one bar. Using the timer on the smart plug, I don't have to monitor it. Start the charger and tell the plug to shut off in X hours. Simple. I plan to keep it between 20 and 80% state of charge for optimal longevity. This thing will outlive me. 😉So glad I bought this. Thanks, Maxoak!
