BLUETTI Elite 300 vs BLUETTI Elite 400

What separates these two

• CapacityThe Elite 300 states 3,014 Wh (nameplateNameplate capacity The capacity printed on the box, in watt-hours (Wh): what the battery holds when new. You get less out of it in use, because the station keeps some back to protect the battery and loses some turning it into 240 V or 12 V power.); the Elite 400 states 3,840 Wh (nameplate), 27% more.This means the Elite 400 holds more energy, so it can run the same things for longer before it needs charging.

• WeightThe Elite 300 states about 26.3 kg (unit onlyUnit only The station by itself, without cables, chargers or a bag.); the Elite 400 states 39 kg (unit only), 48% heavier.This means the Elite 300 is lighter to carry.

• Solar inputThe Elite 400 states up to 1,000 W (at 12–60 V); the Elite 300 states up to 1,200 W (at 12–60 V), 20% more.This means the Elite 300 can take in more solar power at once, so with enough panels in full sun it can charge back up faster.

• Cycle lifeThe Elite 400 states at least 3,000 cycles (until 80% of the original capacity is left); the Elite 300 states 6,000 cycles (until 80% of the original capacity is left), twice as many.This means the Elite 300 is rated for more full charges before its battery wears down to that level.

  Elite 400: manufacturer page (www.bluettipower.com.au) read 29 Sept 2026 The Elite 400 lasts for over 3,000 charge cycles, maintaining 80% of its original capacity.

• UPS switchoverThe Elite 300 states up to 10 ms (how it was tested not stated); the Elite 400 states 15 ms (how it was tested not stated), 5 ms slower.This means the Elite 300 switches to its own battery faster when the mains power it's plugged into cuts out.

Price and price per Wh aren't compared here yet. That needs a second shop selling each one for about the same price (within 10%), which shows the price is real. Today: price, Elite 300 $2,699 and Elite 400 $3,099; price per Wh, Elite 300 89.5¢ and Elite 400 80.7¢.

Can't be compared as the brands list themCan't be compared The two brands give this figure in different ways, or only one brand gives it. For example, one counts battery charges until 80% of the capacity is left and the other until 70%. Set side by side, the numbers would mislead, so both are shown and neither is put ahead.

• AC output, non-stopThe Elite 300 states 2,400 W (continuous or peak not statedContinuous or peak not stated The brand gives one output figure without saying whether it's the non-stop rating or a short burst, so it isn't compared with other stations' continuous figures.); the Elite 400 states 2,600 W (continuous or peak not stated). Neither brand says if its figure is the non-stop power or a short burst.This means the two numbers were measured in different ways, so setting one against the other would mislead.

A difference is listed above only when both brands measure a figure the same way and the gap is at least: capacity: 10% or more; price: 10% or more; price per Wh: 10% or more; AC output, non-stop: 15% or more; weight: 8% or more; 12 V car socket: any difference; solar input: 20% or more; wall charging, empty to full: 20% or more; cycle life: 20% or more; stated warranty: any difference; UPS switchover: 5 ms or more; expansion batteries: one has it and the other doesn't; AC surge: 15% or more. Every comparison on this site uses the same gaps.

Fridge runtime for both

How long each would run an example fridge, a Dometic CFX5 45, with no solar and no driving. Its manufacturer says it uses 0.76 Ah an hour at 12 V when it is 32 °C outside and 4 °C inside. The brands don't publish some of the figures this needs. Where someone has tested the station, their result is used; otherwise both use the same ranges, taken from tests of other stations.

The middle estimates are 1.1 days apart.This means the Elite 400 is likely to run the fridge for longer, but that one unknown figure could close the gap.

The biggest unknown is the station's own drawStation's own draw Power the station uses itself while an outlet is switched on: its screen, its electronics and the circuit that makes 12 V or 240 V. Few brands publish it. Over 24 hours it can add up to as much as a small fridge uses. with the 240 V outlet on. No brand publishes it and no test of this station was found, so 10–26 W is assumed. On its own, it can change the Elite 400's answer by up to 3.0 days, which is more than the gap between the two. The brand doesn't list a 12 V socket12 V car socket A cigarette-lighter style socket that runs 12 V gear, like a camping fridge, directly. Its rating is in amps (A): a 10 A socket supplies up to about 120 W. for the Elite 300 and Elite 400, so their fridge runs from the 240 V outlet through the fridge's mains adapterMains adapter The plug-in power supply that turns 240 V from an outlet into the 12 V a fridge runs on. It loses some energy as heat, and so does the station making the 240 V..

Try another fridge, add solar or driving, or change the assumed ranges:

Charging paths

“Not stated” means the brand's website and manual don't give that figure (checked 29 Sept 2026).

All the specs side by side

Capacity is the nameplate figure in watt-hours (Wh), the one on the box. AC output is the power a station can supply non-stop, not a short burst. Weight is the station on its own. A figure measured another way is shown with a note saying how, and isn't compared with the others.

What neither brand tells you

These figures would help answer the questions above, but neither brand gives them (checked 29 Sept 2026):
