Anker SOLIX C1000 Portable Power Station | 1,056Wh, 1,800W

Anker SOLIX C1000: the 1kWh power station that doubles to 2kWh

The Anker SOLIX C1000 holds 1,056Wh and delivers 1,800W of continuous output, which covers the essentials list most households care about during an outage: a refrigerator, lights, internet, phones and a CPAP machine. What sets it apart from everything else in its class, including Anker’s own newer Gen 2, is that it does not have to stay a 1kWh unit. Add the BP1000 expansion battery and the same power station becomes 2,112Wh.

That matters more than it sounds. Most people underestimate how long an outage will last the first time, and a unit you can double later is a purchase you do not have to make twice.

What the Anker C1000 can run

Estimated runtimes on a full charge, one device at a time, assuming about 85% usable capacity after inverter losses. Double every figure if you add the BP1000 expansion battery.

Key features

Expandable to 2,112Wh

The BP1000 expansion battery adds another 1,056Wh through the same inverter, screen and app. Worth knowing before you compare models: the BP1000 works only with the original C1000, and the newer C1000 Gen 2 cannot be expanded at all. If future capacity matters to you, this is the model to buy.

1,800W output with 2,400W SurgePad

1,800W continuous covers a fridge, a microwave or a coffee maker. SurgePad technology lifts output to 2,400W for heat generating appliances such as kettles and hair dryers. Anker notes that SurgePad suits heating devices rather than precision electronics with strict voltage requirements, so plan motors and sensitive equipment around the 1,800W figure.

11 ports, 6 AC outlets

Six AC outlets, two USB-C ports (100W and 30W), two USB-A ports and a 12V car socket, eleven outputs in total on the US model. Six AC outlets is generous at this size, and during an outage it is the difference between powering the essentials and juggling extension leads.

80% charge in 43 minutes

From a wall outlet the C1000 accepts up to 1,300W and reaches 80% in 43 minutes, with a full charge in under an hour. It also takes up to 600W of solar through an 11 to 60V MPPT input, or charges from a car socket, or from your vehicle’s alternator with Anker’s alternator charger.

UPS switchover under 20ms

Leave it plugged into the wall with your equipment connected, and it takes over in under 20 milliseconds when the grid drops, certified rather than estimated. Fast enough that a CPAP machine, a desktop computer or a router keeps running without noticing. The C1000 is certified by SGS to UL 1012, UL 1778, UL 1973 and UL 60730.

A decade of use, and 28 lb to carry

LiFePO4 cells rated for more than 3,000 cycles to 80% capacity, which Anker puts at around ten years, backed by a 5 year warranty. At 28.4 lb it is a genuine one person carry, which not every 1kWh unit manages.

Choosing your bundle

This listing offers four options, and the right one depends on how you plan to use it.

• Anker SOLIX C1000 on its own. The right choice for home backup where you charge from the wall before a storm. Everything above applies.
• C1000 with the BP1000 expansion battery. Doubles capacity to 2,112Wh. Pick this if you are covering a multi day outage, living off grid at weekends, or you simply want the headroom. Cheaper bought together than added later.
• C1000 with the alternator charger. Charges from your vehicle’s alternator while you drive, far faster than a standard 12V car socket. The option for RV, van and overlanding use, where the drive between stops becomes your charging time.
• C1000 with the water resistant bag. Protection from dust, rain and knocks in transit. Sensible if the unit lives in a truck bed, a garage or a boat rather than a closet.

Anker SOLIX C1000 vs C1000 Gen 2

Both are excellent, and they suit different buyers. Here is the honest comparison.

Which one? Choose this C1000 if expandability matters, or if you want six AC outlets. Choose the C1000 Gen 2 if you want the faster recharge, more output and the lighter body, and you are confident 1kWh is all you will ever need. The Gen 2 is the better standalone unit. This one is the better system.

Frequently asked questions

What is the difference between the C1000 and the C1000 Gen 2?

The Anker SOLIX C1000 is expandable to 2,112Wh and has six AC outlets. The Gen 2 is not expandable, but charges faster (49 minutes to full against 43 minutes to 80%), outputs 2,000W instead of 1,800W and switches over in half the time as a UPS. Pick this model for room to grow, the Gen 2 for a faster, more powerful standalone unit.

Can I add an expansion battery later?

Yes. The BP1000 adds 1,056Wh for a total of 2,112Wh and can be bought at any time. It works only with this Anker SOLIX C1000, not with the Gen 2 or with other Anker batteries such as the BP2000 or BP3800. Buying the bundle up front usually costs less than adding it later.

What does the alternator charger do?

It charges the Anker SOLIX C1000 from your vehicle’s alternator as you drive, much faster than a standard 12V car socket. If you travel between campsites or job sites, it turns driving time into charging time, which is the practical way to stay powered off grid for days.

Can it run a CPAP machine overnight?

Comfortably. A CPAP without a humidifier draws about 40W, so a full charge lasts around 22 hours, more than two nights. With the UPS switchover under 20ms, you can also leave it plugged in as a bedside backup that takes over silently if the power fails.

How long does it take to charge?

The Anker SOLIX C1000 takes about 43 minutes to 80% from a wall outlet, and under an hour to full. From 600W of solar it takes a few hours in strong sun. You can also charge from a car socket or an alternator charger.

Is it safe to use indoors?

Yes. No fuel, no exhaust and no carbon monoxide, so unlike a gas generator it can run in a bedroom or beside medical equipment. It is SGS certified to four UL standards, including UL 1778 for uninterruptible power systems. Keep it on a hard surface with space for airflow.
