Three rows in that table look like ties and are not, and two rows that look unremarkable are where the decision actually sits. Taking them in turn.

The recharge figures are not comparable as published

You will see the Anker advertised as reaching a full charge in 58 minutes. That figure is real, but it is measured with the wall socket and solar panels feeding the unit at the same time, drawing 2,600 W between them. On mains power alone, which is how most people will charge it, the honest number is 1.5 hours. The BLUETTI takes 1.4 hours.

So the two units recharge at effectively the same speed, and the gap most comparisons report between them does not exist. This site quotes the mains-only figure for both, because charging from a wall socket is the case that applies when the power has just come back on and you want to be ready for the next cut.

It is worth knowing that neither unit has to charge that fast. High-rate charging generates heat, and heat is what ages cells. If the unit lives plugged in as standby backup, use the slower charging mode and keep the fast one for when it matters.

Weight: the difference you will notice every time you move it

The Anker weighs 41.7 lb (18.9 kg). The BLUETTI weighs 53.4 lb (24.2 kg). That is a gap of close to twelve pounds on units of the same capacity, and it is the single most tangible difference between them.

Both are two-handed lifts. But there is a real threshold between a unit one adult can carry up a flight of stairs without planning it, and one that becomes a two-person job or a thing you simply leave where it is. Anyone intending to move a power station between a garage, a car and a campsite should weigh this more heavily than any specification on the sheet, because it is the one that decides whether the unit gets used.

If the unit is destined to sit in a utility room and never move, ignore this section entirely.

Expansion: one of these can grow, the other cannot

The Anker accepts an expansion battery, taking it to Expandable to 4,096 Wh. The BLUETTI's own specification table lists it as not expandable, and that is a harder limit than it first appears.

Sizing a power station is genuinely difficult before you have lived with one. Most people underestimate, because a fridge behaves differently from how they imagined and an outage lasts longer than expected. With an expandable unit, that mistake costs an expansion battery. With a fixed one, it costs the whole unit, and you are left selling a perfectly good machine at a loss.

This cuts the other way too. If two kilowatt hours is comfortably more than you need, expansion is a feature you will never use, and paying anything for it is waste. The question is not whether expansion is good, it is whether you are confident about your own sizing.

Cycle life, and whether you will ever reach it

The BLUETTI is rated for 6,000 cycles to 80%. The Anker is rated for 4,000 cycles to 80%. Both quote the same endpoint, which makes this one of the uncommon cases where two cycle ratings can be compared directly. Half as many cycles again is a genuine advantage, on paper.

Whether it reaches you depends entirely on how you use the unit. A full cycle is a complete drain and refill. A machine kept as standby backup, discharged properly a handful of times a year, will not come close to either rating in a human lifetime, and the cells will age on the shelf regardless of how little you cycle them. Somebody living in a van and running the pack flat most days is in a different world, and there the extra cycles are worth real money.

Both use lithium iron phosphate, which is why these figures are in the thousands rather than the hundreds. It is the right chemistry for the job: tolerant of sitting at full charge, far more stable thermally than the alternative, and heavier for it. That weight is not a design failure, it is the trade you accepted when you chose the safer cell.

Two surge figures that measure different things

The table shows 4,000 W against 3,900 W (Lifting Power), which reads like a near tie. It is not a tie, because the two numbers are not the same kind of measurement.

The Anker's is a conventional surge rating: a brief tolerance for the current spike drawn when a motor starts. Lifting Power is something else. It runs appliances above the unit's rated output by reducing voltage.

That distinction decides what you can safely plug in. Lowering voltage works for resistive loads, where less voltage simply means heat arrives more slowly: a kettle, a heater, a hotplate. It does not work for motors or electronics. An undervolted compressor draws more current, runs hotter and can stall, and undervolting a computer or a medical device is not an experiment worth running. The Anker's figure tells you it can absorb a start-up spike; the BLUETTI's tells you it can run a heater larger than its rating. Neither substitutes for the other.

Solar, and working out whether either is enough

The BLUETTI accepts up to 1,000 W, the Anker up to 800 W. For anyone planning to recharge off-grid rather than from a socket, that is a meaningful gap: it sets how fast the unit refills on a good day, and the voltage window decides which panels can be wired to it at all.

Both units sit around two kilowatt hours, which in practice covers a fridge through a long outage alongside phones, lights and a router, with room to spare. Both will run a microwave or a kettle in bursts. Neither will run an electric heater through the night, and nothing this size will.

Rather than trust a rule of thumb, put your own appliance and its actual wattage into the run time calculator, which shows the inverter losses and the compressor duty cycle it assumes instead of hiding them. On fridge estimates, that duty cycle moves the answer more than anything else.
