Anker SOLIX BP1000 Expansion Battery (1056Wh), LiFePO4 Batteries with 10-Year Lifespan, 1056Wh Extra Battery SOLIX C1000

The ability to double the capacity of my Anker power bank (CP1000) is fantastic. I love Anker products across the board and I am never disappointed with them. This battery hooked up with no issues and should really allow me to use my power bank as an emergency backup for several things in the house should the power go out. In the winter time this will help me keep the house warm and the food cold. And in the summer I use this for camping and to power things when I'm away from the grid. Doubling the capacity means even less worrying. And coupled with my solar panels I can keep things going hopefully for a lot longer. The battery is stylish and matches the power back. It fits right on top and both can be lifted together without too much issue (it might be heavy for some but I could handle it no problem). These are solidly built, and super high quality. The ten year life expectancy is also a huge plus. The Black Friday deal put this at under $400 and that was also a huge incentive to buy. I know Anker products are worth the price but a nearly half off deal made this a great value for the price. Highly recommend. Would be great for Van-Life folks, campers, survivalists and off the grid living.

Works as expected doubles the charging span of the see 1,000, but it's not designed to be a home backup except maybe during the power outage. This will be my backup for that or to go camping

The expansion battery makes my c1000 last twice as long. This is my second battery, so now I have over 3k worth of power. Hot swap is great also. No down time. Love Anker

great quality works great

With its massive cable that is attached to the main unit, it is as if you actually had a double- sized main battery- but you can still easily determine the charge percentage of each one.

Excellent calidad

Many reviews state the expansion drains first and then the main station drains and that’s exactly my problem with this setup. The 2 batteries should work in conjunction with each other. Solix at 100%, expansion at 90% and they should both drop around the same % rate 90%/80% and so on until they both need to be charged. They should work as one battery not separate entities Otherwise you’re either 1) draining the expansion to 0% (bad for the expansion battery) and then the Solix kicks in or 2) need to charge the expansion everyday and the Solix never drains at all which means you need to charge everyday and effectively never use the Solix at all or 3) forced to unplug the expansion around 20% and only use the Solix, which defeats the purpose of the expansion itself and you can’t charge the expansion without it being plugged into the Solix So while yes it’s nice to have the extra power and battery storage, you’re almost certainly better off just having 2 Solix and no expansion since the Solix/expansion operates as 2 separate power sources instead of 1 combined battery as it was designed to work. You can’t return the expansion once you buy it!!

Bought this to add to my c1000 unit. Very sleek, excellent capacity, lightweight. Will have to update later for charging review. Solar charging and it's cloudy.

Amazing! Expands my Anker solix c1000 battery. Two double the capacity! Quite and effective! Amazing! Would recommend to anyone!

Easy to add on and fantastic build quality

Long lasting charge

Works as designed I guess, it's doubled the usage of my Anker battery and works very well! Expensive but a good product links easily and gives a greater opportunity to use my own grown electricity supply! The downside is it'll take me a long time to break even😆
