TLDR
- I’ve had my C1000 since May 2025, it has already kept my Starlink and office setup online through 6 power cuts
- It’s portable and versatile, you can run power tools offgrid or even use it for car boot cooking
- There is a newer version on sale, this one is heavily discounted and still more than capable
- Anker are a high quality brand, you can trust this device not to damage your tech and to withstand normal use.
- It has excellent solar integration, you can source your own panel and connect it easily
- Rapid recharge time from the mains
- Generous amount of sockets – USB C, USB A, 12v and 240v
- It won’t run a normal kettle – it trips out at about 2kw but it will run an air fryer or hot chocolate machine easily
- If you are in the market for a backup battery / generator definitely put the C1000 on your shortlist, I am very happy with mine.
Situation – why we needed the C1000 in our lives:
We live in a house sat between four fields on the side of a hill in the Lake District. We are 4.5 miles from the closest shop, a similar distance in the other direction from a pub, and right at the end of the line for power supply. We still do not have fibre broadband.
All of this is great as far as I am concerned – in fact, it’s exactly what we were looking for when we moved here. It does mean we have to be able to take care of ourselves and solve problems on a fairly regular basis.
I am a professional remote worker. I do a few different jobs and they all depend entirely on being able to get online and operate IT equipment. I cannot earn without that infrastructure in place.
It was never really much of a problem until January 2025. Prior to that, we would have the occasional power cut, especially in storms, but by the time I had boiled the kettle on the gas hob, we were up and running again. In January, there was extensive damage to the high-voltage grid in Cumbria, and the recovery teams simply could not get around to all of them. We were off for just under 48 hours. Fortunately, it was at the weekend, so it did not affect work, but we did lose most of our frozen food, and it got us thinking.
I tried hooking an old camping inverter up to the battery of my Volvo with the engine running. It was enough to get the LED displays of the fridge-freezer to come on, but not the compressor.
I looked into getting a generator – petrol or diesel. You don’t really get much for less than £1,000, and then you have to keep it somewhere, replenish the fuel to stop it going off, and run it every month to keep it in good condition. It has to be outdoors when running, and not all of them are weatherproof. It’s another engine to service with oil changes, spark plugs, and so on. And the noise.
I thought about professionally installed house batteries – tempting, as I could benefit from cheap overnight electricity on Octopus. These systems don’t necessarily provide backup power in the event of a cut, and they are certainly not cheap.
Anyway, spring continued and I forgot about it for a while – until the electricity company wrote to me to say the power would be going off for repairs for the whole of a Monday in May. I made plans to work from my wife’s office. It wasn’t a great day – I felt in the way and I didn’t get much done. So I went back to making my own backup plan. A portable power station made so much sense for what I needed.
C1000 Specifications:
The Anker C1000 holds 1056Wh– one kilowatt-hour (kWh), in other words. That’s enough to run a 1kW electric fire for about 50–55 minutes, or a 100W light bulb for around nine hours once you allow for inverter losses. In my case, it’s plenty to run my Starlink setup, laptop, and external screens for seven or eight hours. If I wasn’t running my full complement of office equipment, it would run Starlink for a good 15–18 hours.Alternatively, you could use it to cycle the fridge-freezer every few hours and to run room lighting. If you’re wise with it, that 1kWh can go a long way and make the difference between surviving and being relatively comfortable.
The C1000 can deliver 1800W continuouslyand up to 2400Wfor a short surge. It can recharge to full in as little as 58 minutes, and the battery technology is good for 3,000 cycles to 80% capacity – roughly ten years of normal use. It has 9 output ports, including two USB-C, two USB-A, four 240V mains sockets, and a 12V car “cigarette lighter” style port. You can charge it from solar panels if you have them, and it will also accept input from a car 12V system. It comes with a car charging lead, some solar adapters, and a 240V mains lead.
I talked myself into the idea pretty easily in the end – no fuel to worry about, no noise, no maintenance. I also liked the thought of taking it on camping trips – not something you could sensibly do with a generator.
My Review:
I have had mine for a year now, so I feel qualified to give it a considered review.
I have used it “in anger” for six power cuts, one of which lasted 7 hours, it was more than capable of running my work setup. Several of the cuts we’ve had so far were short but featured the power coming off and on again a few times before stabilising – very annoying if your router has to power cycle each time before reconnecting. I found the C1000’s uninterruptible power supply mode very useful here. You plug the C1000 into the mains, turn it on, then plug your router and computer into it, and it prevents any issues when the mains supply flickers.
I keep the C1000 near our router with a long extension cable next to it. When the power goes off, I plug the router straight in. By the time I’ve run the extension to my computer, the Wi-Fi is back on and I can carry on with my day, only losing a couple of minutes.
I’ve found quite a few other great uses for it:
DIY – When doing electrical work with the power off, I can still run my drills, multitools, and lamps from the C1000. Ideal for chasing in new sockets and fault-finding.
Outdoor DIY – We own a little bit of land, and quite often I need to run a power tool out of range of the house. The C1000 has been more than happy to run drills, cutting tools, and a table saw out and about.
Leisure – I’ve run a Hotel Chocolat Velvetiser in the boot of my Volvo and provided hot chocolate to friends. You could easily run an air fryer from it too (though not a normal kettle – they’re 3kW).
Vehicle / machinery – the 12v “car cigarette lighter” output runs my tyre compressor, very handy if I’ve got more than one tyre to inflate or if I’m pumping up the tyres on my lawn tractor which does not have an outlet. The compressor draws about 120w and soon takes the edge of the vehicle battery whereas the C1000 drives it hard for as long as you need.
I’ve also been experimenting with solar power. I found an old 190W solar panel and was able to get a connector from Amazon for about £15. I was surprised how well it worked – the telematics on the C1000 showed it delivering up to 157W in direct sunlight. A larger 400W panel could recharge the C1000 in around three to five hours of good light. Even my small panel is enough to provide more than I use with my Starlink system and computer. If I was away camping, I think leaving that set-up would keep us in business for mobile phone and iPad charging for a week easily.
In normal use, I have it plugged into a smart socket in our wardrobe. I’ve set a reminder on my calendar to charge it up every three months or so, to make sure it’s ready to go when needed. It also means I can flick it on if it seems likely there’ll be a power cut.
The C1000 has a few other features that I appreciate. There’s a good smartphone app that lets you update the firmware, remotely turn it on, or read its telematics. This is very useful when it’s running, as you can keep an eye on remaining battery power and even the performance of your solar if you have it. I also like that you can set the mains charging speed – I’ve turned mine down to 400W to be gentler on the battery and reduce fan noise. If I was in a hurry, I could turn it up to ultra-fast. I never thought I’d use the built-in LED strip light, but I must admit, it’s been really useful a few times.
The unit itself is very well designed. It’s heavy, but it has two solid carrying handles at the top. It feels premium, built to last. I note that you can buy an extension battery to double the capacity if needed.
All considered, I am extremely pleased with my C1000 and I highly recommend it.
My own device is the first generation C1000, it is no longer on sale so my Amazon UK links will take you to the new model which looks even more impressive.
