Anker SOLIX F2000 Portable Power Station, PowerHouse 767 and 760 Expansion Battery, 4096Wh LiFePO4 Battery with 4 AC Outlets Up to 2400W, GaNPrime Solar Generator for Home, Outdoor Camping, RV

Update: At least Anker stands behind their product. They reached out on their own initiative and replaced both units. New units have all outlets wired in the correct polarity. So I take back what I said about it being a design flaw, but it appears that some units made it out with that defect and my original ones were part of that bad batch. Do use a $10 outlet tester or a multimeter if you have one and check just in case though. It's best to keep electricity only to where it's expected. As a bonus I got to test the power delivery discharging the old units for shipping. Both units held 2350W output rock solid for the half hour or so getting down to 25% charge, so that spec checks out. Original review of the reversed polarity units below for posterity: ------------------------------------------------- Good specs for the price: LFP, GaN, capacity, and power delivery. However as several prior reviewers have noted, they reversed the poliarty on the NEMA 5-20R outlets while the TT-30 is wired correctly. I have two units, both with the same issue, so it definitely seems like this is just a literal design flaw on Anker's part that affects every unit, which I can't believe they haven't rushed in a correction on their assembly line yet after a couple of months of reviewers noting the issue. If you look up the NEMA diagram on wikipedia, you'll find that when you're looking at the outlets with ground at the top, both the 5-20 and TT-30 should have live on the left and neutral on the right. Well, when it's plugged into the wall in pass though mode, the 5-20 has a reversed live and neutral. While devices shouldn't care about the polarity in normal operation (they just need the 120v delta between live and neutral which the inverter does seem to do a good job supplying), you run into hazards especially with simple appliances that often only switch the live wire. For example, if a cheap toaster only cuts off power using what it thinks is the live wire, if you make the neutral live, the heating coils inside may be charged even when it's off. So if you jam a fork in there when it's off, now you've just touched live 120v AC. Now, this will still work with a bonding plug (only use a bonding plug when it's disconnected from the wall) as the inverter simply supplies voltage to whichever leg is not being pulled to ground, but as noted above since the TT-30 and 5-20 outlets are wired opposite of each other, no matter in what state things are in at least one outlet will have the wrong polarity, short of cracking the thing open, voiding your warranty, and fixing the wiring. That Anker's engineers couldn't spend 5 minutes to look at a diagram on wikipedia before writing assembly instructions for what I imagine is a multimillion dollar assembly line doesn't exactly inspire confidence in their competence.

I bought this system to replace a smaller Goal Zero battery / inverter in a small teardrop trailer (T@B - I have it squeezed on its side under the seats). Similar to the Renology power stations, the Goal Zero would not recharge electric bike batteries due to some incompatibility problem (other people have reported this issue). Not only is the Anker battery system much larger, but there are no issues with charging our electric bike batteries after a ride, while camping. The Anker system can recharge from solar power during the day while we are out cycling. Initially we had issues with the extension battery pack refusing to charge from solar once the main battery had been even slightly discharged. This meant that, effectively, only the main battery could be recharged from solar. We sent the information to Anker, and incredibly, they updated the firmware to fix the problem (updated firmware is 2.1.7). I just tested the update, and everything now works fine - the extension battery will charge once the main battery has charged to 100%. This is amazing and personalized customer service that I can't imagine getting from any other large company. We also love how we can recharge all of our USB and USB-C devices overnight from the system without having to switch the unit on. We also use the power station for laptops and sewing machine during the day. The only small niggle is that the connection to the extension battery is very stiff and sticks out quite a way. We have to disconnect it overnight when we lower the seat for sleeping in the trailer. However, this is a very small issue now that both batteries can be recharged each day from solar (we have 200W panels on the trailer and another 200W on the car roof to power our biking and other needs, and remain completely off grid for multiple days).

Anker is the brand of battery back ups that I use for my TVs, internet and more when the power goes out. Had to have the expansion tank! I brought this for my RV. It can run everything together except the AC which is fine. That would just drain the batteries anyway. I run my camper off of the Anker system in the spring and fall when it's cool enough to have the windows open on the RV. I can run this for 8 to 12 hours and then run my generator for three to recharge the batteries. This is less wear and tear on my generator. When it's not powering my camper I wheel it inside and it powers my fridge and freezer for several hours when the power goes out. I don't have the solar setup and don't really need it but that would be a great addition for most. The setup was easy and after that it's plug and play! And no I'm not sponsored by them.... Lol I just really like their stuff!

The Anker 767 Powerhouse is just too underpowered for my needs. I purchased this item based on the ability to connect my RV's shore power to this unit and run my RV on battery instead of gas for a short duration. What I found is that this unit lacks the power to run the RV's 11,000 BTU A/C or a or the RV's 1,000 watt microwave. I tried about everything. I contacted customer service, did a firmware update, installed a ground neutral plug, installed a Soft Start kit. No dice. About all it is good for is to charge the cell phone, run lights, or watch TV for a while. The RV's house battery and an inverter can do all that. Fortunately, Anker was quick to issue a return authorization without too much hassle. I really liked the unit otherwise. It just lacks the power I need. Also, Anker's email support is pretty useless. You send them an email, you get a canned response the next day, you reply to that email and it takes another day for them to get back to you with another canned response. Bottom line is that I am not at all impressed with the whole Anker experience. As a result, this thing is going back and I will be purchasing a more powerful unit from one of their competitors.

very well packed complete with Thank you note from employees , well designed and works like a charm.
