Note (Original review for main unit at end - most recent (about expansion batteries) top). 8/7/24: With everything automated I've had absolutely no complaints. For whatever reason power goes out at 7am now quite regularly for about 10-15 seconds - this battery keeps my office going like nothing happened. I continue to offload power during peak hours without even a thought (automated plugs scheduled to turn on/off). The Anker app continues to work amazingly. Couldn't ask for better. I rarely hear the fans unless it is charging (and even then it's not loud if you keep the charging around 400w). I did end up getting a C800 - just cuz I loved the 1000 so much. lol. I have it (acting as an UPS) for our ISP router and lamps in another room during peak hours - and it's a bit more mobile when I need power in places away from a plug. Also works nicely with the Anker App (both show up side by side). My little place is ready for the rain and storms this fall/winter! I am planning on using these batteries for their full lifespan or until something major comes out. 6/3/24: Have had 0 problems with these batteries. Been using them almost every night to power my office from 4pm-9am. Excellent product - very happy with it. It's comforting knowing that I could power my place (fridge, internet, TV, computers) for at least 24 hours if we lose electricity again. Meanwhile, they function as power surge / protection and offload power to cheaper off hours (actually saving some money doing this - albeit very little but it's adding up every day). I bought some automated plugs that my phone turn on/off when it's 4pm-9am so I don't have to do anything to "offload" my power to cheaper times. LFP batteries are great - Anker is great. Hope y'all have a great 2024! 4/14: Finally - Firmware Update Fixes External Battery Issue A few days ago Firmware 1.4.3 came out - looks like this has fixed the issue where when using the battery as an UPS and pull power for long periods of time then reconnect power - charging would refuse to happen unless one powered down/back up the external battery. Been using my C1000 + external battery now for awhile to power my office from 4pm - 9am (averaging 70% of the external battery to 100% of external battery). Been working great (got in the habit of manually pressing the external battery button to power it down/back on every morning - so it would charge at 9am - looks like I don't have to do any anymore). :D Very happy with these batteries! Got my power setup for years to come. 3/10: Latest Update External battery still needs me to press the main button on/off for charging to happen almost every day (running on batteries all night, then smart switch turns power back on, the unit won't charge till I turn on/off the expansion battery via front button), which is a little frustrating but not a deal breaker since it's right next to me. I bought a set of 120mm silent fans to cool both units, they seem to keep the fans off for the most part while running on battery or UPS pass through power (internal fans always run when charging - but very low). Most of my usage is around 200w even during gaming nights. We'll see how it does in summer when my room gains 10-15F+. Been using this battery as an UPS offloading my entire office power from 4pm-9am with smart plugs. Very happy with it. Works well. Comforting knowing if we have another day or two power outage, I'll be able to keep everything running during then. 3/3: Notes on Expansion Battery. Still Happy With Unit! Been using this device with a smart plug to automatically cut power at 4pm to 8am and for the most part it's been working flawlessly. Every few days it'll get in a weird super slow charging mode where it says remaining charge 4 days and never enter UPS mode (I use this as an UPS). Usually restarting the expansion battery works for it to "reset" and charge then enter UPS mode. Only a small inconvenience with the Expansion Battery (using it as an UPS). App is amazing. Batteries are amazing. Device works perfectly as a home office backup system. I plan on using this setup for a long time until a new battery technology comes out. Will report back if I ever get to use this thing in a long outage (powering the fridge, TV, other rooms). 2/24: Expansion Battery Quirks Noticed some interesting behavior with the Expansion battery. If I plug the C1000 and the expansion battery into an outlet that fails to provide the power that the Anker C1000 is asking for, the entire thing goes into a weird passthrough mode and will refuse to charge (no matter how many times I plug/unplug from power) -- until I turn off the expansion battery and then turn it back on (lucky to figure this out). Initially I thought I broke it, but just turning off expansion battery (press holding expansion battery power button for a few seconds) and then back on returned charging to normal. I see how this has affected some other reviewers. Either removing the massive cable for a few seconds or pressing and holding the button on the front seems to fix this (until it happens again). I'm very happy with this setup and have been using it to offload my office power from 4pm to 8/9am very successfully. I usually get the expansion battery down to 22% with this setup. If I want to exercise the main unit's battery, I'll just press and hold power for 3 seconds on the expansion battery (no removal needed) and use the main unit for a night. Very convenient! (Using this as an UPS for my office - see below). 2/22: Expansion Battery Arrives! Absolutely loving this thing. I'm using it to offload my office usage during peak hours (4-9pm). I've had no quirks at all, no complaints. So happy with it, I got the expendable battery (today in the mail). Cable for expendable battery is HUGE - almost doubles the width of the unit... It is not movable whatsoever, so consider that if you get it. When initially plugged into the main unit the expendable battery would only charge at 300w despite being set to 1000w (default). After it warmed up from 55F (shipping?) it started charging at the full rate - so there's definitely some battery management going on. With this thing I should be able to run my entire office for more than 24 hours easily. I bought a silent thin USB Desk fan (just for experimentation) - and this helps keep the unit 10-15F cooler and I never hear the fans, even if pulling close to 160w. We'll see how it does in the summer time. I sent in a suggestion to Anker asking them to include an option to log wattage draws/pulls since I use this as an UPS primarily. Also suggested a way to cap the battery % at 80% for longevity. They agreed and said they'd send it to their developers. (Cool!). Very happy with this unit. Glad I waited for LFP power generators. 2/12: Original Review on Main Unit Only Initial review (2 days of usage): This is my first battery power generator. I've been watching the market for a long time and didn't want to spend $1000. When we recently had a power outage (6+ hours), I noticed my 256whr Anker couldn't power our fridge due to the startup load. So, the SOLIX C1000 was the obvious choice for cost and power provided - was able to get it on sale for $650. Takes about a week to ship - UPS with almost no updates till it's at your front door. I've played with this now for a few days... This thing is amazing. It powers everything and anything I throw at it. I can put my 1500w UPS on it and power my entire office without a problem ( the 256 wh Anker 521 instantly shuts off with same load despite ~100-49w constant draw ). I can control and see vital stats via my phone without having to bend over and check the screen. I have run my entire office off of this battery for hours and only used 10% of the battery capacity. I purchased some drop cords to be able to power the fridge/living room if we have another power outage. Will report back on experience when/if this is used. The recharge rate is amazing, close to 800w and slows down to 600w as it gets closer to 100%. The UltraFast Charging is really nice but expect a lot of fan noise the moment this is turned on. Speaking of fan noise, I am currently using it as an UPS for my office - plugging my 1500w UPS into it and it powering 2 desks (monitors/devices/2 computers). The low fan only came on a few times while powering this setup for several hours (~87-90w constant draw (150w top)) - it's barely audible but considering my previous setup was 100% silent, this is going to probably be temporary as it is winter right now and I imagine the fan noise will be come more of an issue in the summer. I noticed the device was sitting around 83F during very light usage and 95+F during battery draw in a cold winter room <70F. Putting a desk fan on the device's vents instantly drops the internal temperature 10+F so it looks like it wants to sit around 80F in UPS mode. So I wouldn't put this in a closet or in a place that has closed ventilation. Build Quality? It's plastic. But heavy duty plastic. But for $650 I wasn't expecting a metal chassis I guess. Low fan noise is barely audible and doesn't sound bad. The included cables are VERY short and very bulky. The unit does not creak when carrying it around and it feels like it could survive a good drop. Note: When I first got the unit, no amount of pressing and holding the power button turned the device on. Was initially worried but once plugging it into the wall, everything started operating like normal. Seriously considering the attachment battery as it would effectively double my ability to power the house in an outage (right now estimated at around 11-15 hours without conserving). The Anker app is great - I just wish it had more features and ability to record power usage instead of having a few second stats view. But I can't complain, it does what it does well - have had no problems with it. Will report back as I continue to use this device daily.

Update: Returned home after a 30 day trip back in May 2024, traveling from NC to upstate NY in our northstar SC 650,. We used this the Solix C1000 with the expansion battery everyday. Although It won't power our rooftop AC, it powered everything else. Came in super handy during quiet hours when we wanted to use our microwave, or keurig coffee maker and so on. We do carry a generator on board so at the end of everyday around 4-6 pm, we would start our generator and backcharge our entire system. Our onboard solar system would charge our "house battery" but the generator would top off the anker system in about 1-1.5 hours depending on how much power was drawn off the system. We keep the system in our camper and backpower through the shore power hookup. It worked flawlessly for the entire trip. It's pretty handy given the weight, I put the main system where we want it and then stack the auxiliary battery and hook them together with the provided cord. No regrets on this purchase to date. The C1000 and BP 1000 work well for our specific needs and physically handling the system wrt weight is just right! Hope this update helps someone out who is looking for a similar system for a similar application. After purchasing the solix C1000 and then partnering it with the BP1000, I have doubled the output watts I desire to power my northstar sc650 truck camper over a longer offgrid experience. Although I've not tested it on a multi day trip yet, but testing over several hours and running the things I normally would on shore power, I am extremely happy with what it can now power over extended periods of time. Literally running multiple items from our microwave, furnace, hot water heater, and more, when plugged into the surge pad socket with a 15 amp cord I am essentially running everything I need when I need it. The BP1000 discharges first and then will consume power from the C1000 and Vice-versa when charging the system back up. I believe that the system is setup this way so that the user will always have control over power charging and discharging The system does not have a pass through charge function but rather works like a UPS system in the sense that when plugged into shore power and backcharging, if power is needed to run something, the system will stop charging and immediately switch into ups mode and power what you need in the moment. Our plan is to use this system in campgrounds during quiet hours when gas generators cannot be used. Based on our particular wants & needs, I Would highly recommend. I wanted something small but that packed a high watt output when I need it. So far, so good. Boondocking in my northstar truck camper I am able to backpower the entire camper with the Solix C1000 for about a 24 hour period. This depends of course on what I am running. Occasional microwave oven use, my fridge on propane setting, lights, water pump, even the hot water heater and hot air furnace, again, limited high use items. Only used so far on 2 overnight trips. Next morning I use an 1800-2200 watt generator to power the anker back to full from about 15% only drawing a set watt charge of about 750. The generators rpm only increase a little bit and the anker is charged in about 1 hour and 30 minutes. I could increase my charge watts to 1000 and be done inside of 50 minutes or less but I want to break the unit in several charge cycles first and I like running my generator on eco mode. The anker is not heavy at only 28 lbs and I can set it up on my campers kitchen counter or just about anyplace else inside my rig. I bought it for $650 from amazon, anker Direct, and it shipped to my house in under 5 days and came in just under $700 total, a great buy in my opinion. I am looking to eventually buy the expansion battery to give more power in depth but am in no rush at this point. I am 100% satisfied with this small yet powerful unit. It definitely lives up to what it says it can do, also, the app is simply incredible. Great job to the folks at anker. Highly recommended, just do your homework on what you plan to use it for. I've been a goal zero fan for years but it's the older led acid yeti 400 and 1250 units. Great products and they still work great, I also have the ego nexus system and run 7.5 amp batteries on it, again, great units all around but this anker system takes the cake. Size, weight, power output, and charge times is what sold me!! Happy shopping.

I really like the product. The charging speed is really quick so you’re ready to go fast. All the features are super easy to understand. I haven’t tried yet to solar charge but it’s a functionality that I’m looking forward to try. It’s pretty easy to carry since it’s pretty lightweight. The item works great in case of emergency or camping you have plenty of power and time.

After seeing many good reviews for the Power Station, I decided to purchase one for my camping trips. I am glad I did. I have another Portable Power Station from Conpex with similar "Specs", but, oh boy, the difference is huge! In combination with my 400W Solar panels, this thing basically never runs out of power when I use it with my electrical camping gear. Although I never had to use it for this purpose, I also think that should there ever be a power outage the Solix C1000 will be a good addition to my household to keep essential appliances running. AAA+++

So far so good. Works great. Have not really tested it yet but will soon.

very fast delivery, very nice product.

I mainly purchased this C1000 for use during power outages, to run the fridge, charge devices, to power lights and maybe run the espresso maker! Another secondary use case is for when we go on trips. To test the unit, I connected our 30” fridge/freezer and the peak power draw was around 400 watts and I believe it can run it for 10 hours easy! Then did more tests trying the panini grill, the coffee maker, the water kettle and the vacuum cleaner (1500w)! The fan does become loud under load but I did not find it annoying. The Anker app allows full control of the unit and provides useful information on the remaining charging time and power consumption. In terms of build quality it is excellent, and feels durable. You need to be aware that the return policy is strict. And you can return the unit for a refund or replacement only in case of a manufacturing defect or if the unit is damaged.
