BLUETTI Elite 300 review
BLUETTI Elite 300 Portable Power Station
By Tom Calder
Three kilowatt-hours in 26.3kg: BLUETTI says Frost & Sullivan certifies the Elite 300 as the world's smallest 3kWh portable power station, and it's certainly compact for its capacity. You get 2,400W with 4,800W of surge, 10ms UPS switching, a 140W USB-C port and a 12V 30A socket for a campervan, with a LiFePO4 battery rated for 6,000 cycles. It can't take add-on batteries, and the solar and car cables cost extra. Its £1,399 on 10 October 2026 was a sale price (from £1,599) due to end on 14 October.

Our review
Three units of electricity in a box two people can carry: the Elite 300 holds 3,014.4Wh at 26.3kg, with 2,400W from two UK sockets and a battery rated for 6,000 cycles. Its strength is how much it does without accessories, from a 140W laptop port to a 12V 30A feed for a campervan fridge. It suits a household wanting a day or two of essentials in one place, or a van owner who wants one box for both jobs.
What the numbers mean
By the site's planning method (90% depth of discharge, 85% inverter efficiency, 10W for the unit's own draw) about 2,300Wh of the 3,014.4Wh reaches your appliances. 2,400W continuous covers any plug-in appliance bar a 3kW kettle, with 4,800W of surge for compressor starts, and Power Lifting accepts purely resistive loads rated 2,400W to 4,800W while holding actual output to 2,400W. The 6,000-cycle rating means a full cycle every day for over sixteen years before capacity falls to 80%; BLUETTI cites a Frost & Sullivan certification that no 3kWh portable unit is smaller.
In a UK power cut
By our runtime method over the appliance-draw dataset, a fridge-freezer lasts 38 to 105 hours, a router 3 to 5 days, a CPAP on blower alone 3 to 6 days (28 to 74 hours with a heated humidifier), a laptop 29 to 58 hours, a television 10 to 54 hours and a gas combi boiler's electrics 17 to 51 hours. Fridge-freezer, router, four LED bulbs and a charging phone together give 14 to 42 hours; with the combi boiler, 8 to 25 hours. Boilers are hard-wired, so that needs an electrician's changeover first. A chest freezer alone runs 2 to 3 days.
A 2.2kW kettle runs normally. A 3kW kettle needs Power Lifting mode, which holds it to 2,400W, about 40Wh a minute or 1.7% of the usable battery, so it boils more slowly. BLUETTI rates the switchover at 10ms, against 15ms for the Elite 200 V2 and Elite 400 and 20ms for the Apex 300.
How it compares
The BLUETTI Elite 200 V2 is the one to weigh against it: 2,073.6Wh and 2,600W at 24.2kg, the same 6,000-cycle rating but a 15ms switchover, and a 1,000W solar limit against 1,200W here. The BLUETTI Elite 400 adds 826Wh and wheels but weighs 39kg and is rated for half the cycles. The BLUETTI Apex 300 has less built in (2,764.8Wh) but 3,840W and add-on packs, at 38kg. See BLUETTI power stations.
Living with it
The UK AC input is 2,300W. BLUETTI's page puts Turbo charging at 80% in 78 minutes with mains and solar together and a full charge in 1.6 hours from the mains alone; the manual gives 2.8 hours to full in Standard mode at 1,200W and 4.2 hours in Silent mode at 800W. Charging from empty costs about 79p per full charge at Ofgem's October to December 2026 cap rate of 26.32p per kWh, before losses. Solar input is 1,200W at 12 to 60V, but the solar and car cables are not in the box. It measures 366 by 305 by 297.5mm; BLUETTI's handling table says two people for 18 to 32kg. Ports are a 140W and a 100W USB-C, two USB-A sharing 15W by the manual, a car socket and the 12V 30A terminal (the two 12V outputs share 30A). Wi-Fi and Bluetooth, a five-year warranty on BLUETTI's page, and 30-day returns from BLUETTI UK on unused units.
Safety
It is IP20, so keep it out of the rain. The manual asks for a well-ventilated charging spot, allows charging from 0°C to 40°C and discharging from -20°C to 40°C, and for storage says 40 to 60% charge, between -10°C and 40°C and below 35°C if left for over a month, with a full cycle every six months. It names a dry powder extinguisher and classes the USB-C, car and 30A ports as PS3 under IEC 62368-1. General guidance is in our lithium battery fire safety guide; if you also keep a petrol generator, read how to run a generator safely: unlike the Elite 300, it must never run indoors.
Our verdict
This is the pick for a household that wants more than a day of fridge, boiler and broadband without committing to a 39kg or 51kg unit, and for anyone who will cycle it often, because its 6,000-cycle rating is among the longest on our site. Skip it if your cuts are short and your loads are small: a 1kWh unit covers an evening for far less and the ones we list weigh about 11 to 12.5kg. And if you expect to add batteries later, it cannot take them; see home backup power for the units that can.

Who shouldn't buy this
Don't buy it if a fridge, router and phones through a day's cut is the job: the 2kWh Elite 200 V2 does that for £500 less.

Questions
Can the BLUETTI Elite 300 run a fridge-freezer?
Yes. A fridge-freezer averaging 12 to 51W runs for 38 to 105 hours on the 3,014.4Wh battery by the site's runtime method, and the 4,800W surge covers the compressor start.
How long does the Elite 300 take to charge?
BLUETTI quotes 80% in 78 minutes in Turbo mode with mains and solar together, and a full charge in 1.6 hours from a UK socket alone. Standard mode takes 2.8 hours and Silent mode 4.2.
Can the Elite 300 run a 3kW kettle?
Only with Power Lifting mode on, which BLUETTI's manual says handles purely resistive loads of 2,400W to 4,800W while still delivering 2,400W, so the kettle boils more slowly. A 2.2kW kettle runs normally.
Does the Elite 300 come with a solar cable?
No. The box holds the unit, an AC charging cable, a grounding screw and the manual. Solar and car charging cables are sold separately, so budget for them if you plan to use the 1,200W solar input.
