Anker SOLIX C1000 Gen 2 Review: Do You Actually Need a Power Station?

Verdict

Buy the Anker SOLIX C1000 Gen 2 if you genuinely need backup power: it tops up to full in under an hour, runs a fridge or a laptop setup through an outage, and is light enough to throw in the car. Skip it if your only worry is the occasional phone charge — you are about to spend serious money on a 11 kg brick you will use twice a year. Most people asking "do I need a power station?" actually need a £20 power bank.

Who it is for

• Buy it if: you camp or van-life and want to run an electric cool box, a coffee maker or a projector off grid; you want a quiet home-UPS for a router, NAS and monitor during the UK's increasingly frequent blackouts; or you do outdoor work where mains is nowhere near.
• Don't buy it if: you just want to keep a phone and headphones charged on a weekend away (a 20,000 mAh bank does that for a twentieth of the price); you live in a flat with no space to store an 11 kg box; or you expect it to heat a room or run an electric heater for long (it will, briefly, and then it's empty).

Key specifications

What stands out

• The recharge speed is the headline. Anker claims a Guinness-world-record fast charge for the 1,024 Wh class, and the figures back it up: ~49 minutes to full with UltraFast mode enabled in the app. Independent lab testing measured a real charge rate around 1,100 Wh/hr. For someone who only thinks about backup power when the sky goes dark, "plug it in while you find the torches" is a genuinely useful trait.
• It is compact for the capacity. At ~11 kg and roughly the footprint of a small microwave, it is one of the better power-to-weight units in the 1 kWh class. You can carry it one-handed and stash it in a boot.
• Real-world output is honest. OutdoorGearLab's load bank pulled 890 Wh of the claimed 1,024 Wh — about 87% usable, which is excellent for the category and means the "runs a fridge overnight" marketing is not fantasy.
• The 2,000 W inverter has headroom. That is enough for an induction hob on low, a kettle briefly, a full-size fridge compressor, or a whole router-plus-NAS-plus-laptop home-office UPS setup.
• Quiet until it isn't. At light loads (charging a laptop, running a fan) it sits near silent, ~20 dB. The app and display are well regarded and Anker's support has a decent reputation.

Where it falls short

• The fan gets loud under load. This is the single most repeated complaint across professional reviews and owner threads. Under heavy draw or fast charging the fan steps up several levels and becomes an irritating whine, not a benign hum — enough that reviewers say they would not sleep in the same room with it running flat out. If you plan to run it in a tent or a bedroom overnight, temper expectations.
• Gen 2 dropped the expansion battery. The original C1000 could take an extra battery pack to double capacity; the Gen 2 cannot. Anker says this was to cut weight and size, but if you think you might want more than 1 kWh later, you are now committed to buying a second unit. For a "buy once" prepper mindset that stings.
• No built-in light. Gen 1 had a light bar; Gen 2 removed it. Minor, but annoying if you actually camp.
• UK plug reality check. The unit is 120 V native in its US marketing (15 A AC). UK buyers get a region-appropriate plug and 230 V outlets, but it is worth knowing the headline specs are written around the US model — verify the exact UK socket count and voltage on the listing before you assume.
• You are paying for capability you may never use. A large share of "power station" owners discover theirs sits in a cupboard. The honest question is not "is it good?" (it is) but "will I use it enough to justify the space and the spend?"
• Brand-recall nervousness. Some buyers note Anker has had recalls on smaller power products in the past; not a strike against this model specifically, but worth knowing if you are paranoid about leaving a big battery on charge unattended.

Alternatives worth considering

• Do you even need a power station? For phones, tablets and a laptop on the move, a sensible charging setup and a 20,000-30,000 mAh bank costs a fraction and weighs nothing. Start there.
• EcoFlow DELTA 3 / DELTA 3 Plus — the direct rival; often on sale, expandable, and a common pick for the same 1 kWh job. If you want room to grow capacity, look at our EcoFlow River 3 Plus take.
• Jackery Explorer 1000 v2 — similar capacity, a slightly more "consumer" feel, frequently discounted. Better if you want the most established name and don't need 2,000 W.
• Smaller Anker (C300) — if your use is charging gadgets and running a small fan, this is half the weight and a quarter of the outlay.

Before you buy, it is worth questioning the whole category: our "is it worth it?" frame applies to almost every gadget — the cheapest thing that actually solves your problem usually wins.

Bottom line

The C1000 Gen 2 is a genuinely good power station: fast to charge, honest on capacity, portable for its class, and from a brand that will still answer the phone in five years. But "good" is not the same as "necessary." If you have a real, repeatable need — off-grid trips, a home-office UPS, or outage prep you will actually use — it is a sound buy. If the need is hypothetical, you are better off with a power bank and the £400-£600 still in your account. Buy the capability when the use case is real; otherwise, don't.
