Display

Neither product is a gaming device, so “display” here means the built-in screen and app experience. The Anker SOLIX C1000 generally wins because it is positioned as a more premium home-backup product, and that usually translates into a clearer status display and more useful battery/input/output monitoring. EcoFlow’s app ecosystem is also strong, but on the RIVER 2 Pro you’re working with a smaller-capacity unit, so the screen is more about basic state-of-charge and charging status than deep backup planning. Winner: Anker, because the larger system benefits more from detailed monitoring.

Performance

This is the biggest difference. The Anker SOLIX C1000 delivers 1800W continuous output with a 2400W peak, and it has 1056Wh of LiFePO4 storage. That extra headroom matters for kettles, microwaves, laptops, routers, fans, and more demanding appliances during a power cut. The EcoFlow RIVER 2 Pro offers 768Wh and 800W output, with X-Boost up to 1600W for some higher-wattage devices, but X-Boost is not the same as true sustained output. In real UK household use, the Anker is far more capable of running a wider range of gear without tripping. Winner: Anker, decisively.

Build quality and design

Both brands have a good reputation, and both use LiFePO4 chemistry, which is the right call for longevity and safety compared with older NMC-based designs. EcoFlow’s RIVER 2 Pro is the more compact and easier-to-carry unit, which makes sense for camping, car boot use, and small flats. The Anker C1000 is heavier and more substantial, but that’s the trade-off for a much larger battery and higher inverter output. If you want something that feels like a true home-backup appliance, the Anker’s design is more convincing. If you want a grab-and-go power station, EcoFlow is easier to live with. Winner: tie on pure build quality; Anker wins on serious-use design, EcoFlow wins on portability.

Battery life

For battery life, the Anker wins clearly. 1056Wh versus 768Wh is a meaningful gap of 288Wh, which can translate into hours of extra runtime for low-to-moderate loads like Wi-Fi routers, lights, charging phones, or a laptop. Because both use LiFePO4, both should offer long cycle life, but the bigger battery in the Anker gives you more usable energy per outage and fewer recharge interruptions. If you’re trying to ride out a longer blackout or keep essential devices going overnight, the C1000 is the stronger choice. Winner: Anker.

Price and value for money

EcoFlow wins on upfront price: £499 versus £599, so you save £100. For that money, you still get LiFePO4 chemistry, fast charging, and a respected brand with a strong app. However, value is not just about sticker price. The Anker gives you 38% more battery capacity (1056Wh vs 768Wh) and more than double the continuous AC output (1800W vs 800W), which is a major upgrade for only £100 more. If you’ll actually use the extra power, the Anker is better value. If your needs are modest, EcoFlow is the cheaper sensible buy. Winner: Anker for overall value, EcoFlow for lowest purchase price.

Game library/features

Neither unit has a “game library,” so the relevant comparison is feature set: charging speed, output flexibility, and ecosystem. EcoFlow advertises 70-minute fast charging and X-Boost, which is useful if you need a quick top-up before a trip or a storm. Anker claims a full charge in 58 minutes, which is even faster on paper, and that’s a big advantage for emergency preparedness. The Anker also has the stronger power envelope for more demanding devices, while EcoFlow’s feature set is better suited to lighter portable use. Winner: Anker, because faster charging plus higher output is the more useful feature combination.

Overall user experience

For most UK buyers who want one power station to cover outages, home essentials, and occasional camping, the Anker SOLIX C1000 is the better all-rounder. It has the larger battery, higher inverter output, faster claimed recharge, and more practical headroom for real domestic loads. The EcoFlow RIVER 2 Pro is easier to carry and cheaper, and it remains a solid LiFePO4 option for phones, laptops, routers, and small appliances. But it is simply not as capable when the job gets serious. Overall summary: choose the Anker if you want a genuinely useful backup power station; choose the EcoFlow only if portability and saving £100 matter more than runtime and output.
