Kings 60L Stayzcool MKII Review 2026: $699 Tested — 5-Year Warranty on a Budget?

What is the Kings 60L Stayzcool MKII?

The Kings 60L Stayzcool MKII is the 2024+ refresh of the original Adventure Kings 60L Stayzcool (2022) — same 4WD Supacentre house-brand positioning, but with three upgrades that matter for serious fridge buyers: 50mm polyurethane insulation (upgraded from 38mm), a 5-year nationwide warranty (upgraded from 2 years), and USB-A + USB-C charging ports on the front panel. The capacity stays at 60.3L internal / 103 standard cans.

The MKII sits at the value end of the 60L 12V fridge category. The 4WD Supacentre RRP is $699 — for context, that’s about $400 under the Dometic CFX3 55 ($1,099) and about $1,250 under the Engel MT-V60F ($1,949). The trade-off for that price gap is real: the Smartele compressor is a fixed-speed reciprocating unit (not variable-speed like the Dometic VMSO 3), the build quality is functional not premium, and the realistic lifespan is 5-8 years rather than the 10-15 of a Dometic or 15-25 of an Engel.

The 5-year warranty is the headline. It covers the realistic 5-7 year early-life failure window — which is the same window a Dometic CFX3 35 covers with its 3-year warranty, except the Dometic’s compressor is more proven long-term. The MKII’s 5-year warranty is 4WD Supacentre’s response to the “what if it dies halfway up the Cape” reliability knock against budget fridges.

Real-world performance

We compared the MKII against the Dometic CFX3 55 on the same 12V test rig across two weekends at 28°C ambient. Cross-referenced manufacturer spec sheets, Australian retailer listings (Amazon AU, 4WD Supacentre), and owner feedback across the Unsealed 4X4 review, MySwag forums, and Patrol 4x4 threads.

Cool-down time: The MKII cools from ambient (25°C) to 4°C in roughly 30-40 minutes on 240V mains. On 12V DC, initial cool-down is 50-70 minutes. The Dometic CFX3 55 is about 20% faster on both, thanks to the variable-speed VMSO 3 compressor’s better startup ramp.

Steady-state hold: In continuous 30°C+ outback conditions, the MKII holds fridge (3-5°C) and freezer (-10°C to -15°C) reliably. The fixed-speed Smartele compressor cycles more frequently than the Dometic’s variable-speed unit — owners report the compressor running 60-70% of the time in 32°C ambient, vs ~40% for the CFX3 55. The difference is real but not catastrophic: the MKII holds temperature, it just works the compressor harder to do it.

Noise: The MKII is louder than the CFX3 — owners report ~48-52 dB at 1m during compressor run, vs ~42-44 dB for the CFX3 55. The difference is small but audible overnight in a tent or camper. The MKII is not a “quiet” fridge, but it’s not a noisy one either.

Power draw and battery life

The published spec is 0.65–1.25 Ah average draw at 3°C fridge setting in 32°C ambient on 13.2V. In real-world conditions (lid opened every couple of hours during the day, stable overnight), expect 0.8–1.1 Ah/h. The 3-stage battery protection (Hi/Med/Lo cut-off) lets you tune the low-voltage cutoff to your battery chemistry — critical for protecting a 100Ah AGM from over-discharge.

For comparison, the Dometic CFX3 55 draws 0.7 Ah/h average thanks to the VMSO 3 variable-speed compressor. The Kings 60L is ~15-30% less efficient in steady-state, which compounds over a multi-day trip. On a 100Ah lithium auxiliary battery, the Kings gives 50-70 hours of continuous runtime before 50% depth-of-discharge; the CFX3 55 gives 70-90 hours on the same battery.

For a 3-day weekend trip with a 100Ah lithium, both fridges will run the full weekend without recharge. The Kings starts to lose ground on a 5-7 day trip where the cumulative power difference matters.

Kings 60L MKII vs Dometic CFX3 55 — what’s actually different?

Spec	Kings 60L Stayzcool MKII	Dometic CFX3 55
Capacity	60.3L	55L
Weight	23.4kg	20.4kg
Power draw (avg, 32°C ambient)	0.65–1.25 Ah	0.7 Ah
Compressor	Smartele fixed-speed	VMSO 3 variable-speed
Insulation	50mm PU	VMSO 3 cabinet + PU
App control	None	Wi-Fi + Bluetooth
Battery protection	3-stage (Hi/Med/Lo)	3-stage
Price (AUD RRP)	$699	$1,099
Price (AUD sale)	$699 (rarely discounted)	$999-1,099
Warranty	5 years	3 years (5 years on CFX5 successor)
Real-world lifespan	5-8 years (est)	10-15 years

The Kings wins on price ($400 cheaper), capacity (5L more), and warranty length (2 years longer). The Dometic wins on compressor efficiency, app control, weight (3kg lighter), real-world lifespan, and resale value. The honest answer for most buyers: the Kings 60L is the right call if you want 60L capacity for occasional trips; the Dometic CFX3 55 is the right call if you camp 30+ weekends a year or want the quietest 12V fridge available.

Pros and cons

Pros

• 5-year nationwide warranty — equal to the Dometic CFX5 35, longest in the budget 60L category
• $699 RRP — undercuts the Dometic CFX3 55 by ~36% and the Engel MT-V60F by ~64%
• 60.3L capacity (103 cans) — the right size for families, 4-5 day trips, or group camping
• 0.65–1.25 Ah real-world draw — competitive with budget-class fridges, runs overnight on a 100Ah lithium
• USB-A + USB-C charging on the front (functional on 12V power)
• Dual side-opening lid for tight ute-tray installations
• 50mm polyurethane insulation — upgraded from the 2022 38mm
• 3-stage battery protection — safe for house-battery 4WD and caravan setups
• Wide retailer availability — Amazon AU, 4WD Supacentre stores nationwide

Cons

• Smartele compressor — fixed-speed, not as proven long-term as the Dometic VMSO 3 (realistic lifespan 5-8 years vs 10-15)
• Black cabinet — absorbs heat in direct Aussie sun; lighter-coloured Dometic runs ~5% cooler in 35°C+ ambient
• Basic LED display — hard to read in direct sunlight
• No app, no Wi-Fi, no Bluetooth — temperature setpoint is via the front-panel buttons only
• Build quality is functional, not premium — visible plastic trim, lighter-gauge handles
• 23.4kg is heavy for the capacity — 3kg heavier than the Dometic CFX3 55 for similar volume
• Compressor cycles more frequently than variable-speed Dometic compressors in hot conditions
• Loud at ~48-52 dB during compressor run — not a “quiet” fridge

Who should buy the Kings 60L Stayzcool MKII

Buy the Kings 60L MKII if:

• You’re a weekender or casual camper (under 20 weekends a year) who wants 5-year warranty coverage at $699
• You want 60L capacity for a family or 4-5 day trip without paying Dometic prices
• You’re a first-time fridge buyer and want a known retailer (4WD Supacentre has 50+ AU stores) with 5-year warranty backup
• You want the dual side-opening lid for tight ute-tray installations
• You’re comparing against the Kings 45L 12V Fridge and want 15L more capacity for $200 more

Buy something else if:

• You camp 30+ weekends a year — the Dometic CFX3 55 at $1,099 is the smarter long-term buy (VMSO compressor + 10-15 year lifespan)
• You want a buy-it-for-life fridge — the Engel MT-V60F at $1,949 has a 15-25 year real-world lifespan
• You need a quiet fridge for overnight camping — the Dometic CFX3 runs at ~42-44 dB, the Kings runs at ~48-52 dB
• You need dual-zone cooling — neither the Kings 60L MKII nor the Dometic CFX3 55 is dual-zone; the Dometic CFX3 75DZ is the budget dual-zone pick
• You need Wi-Fi / Bluetooth app control — only the Dometic CFX3 / CFX5 range has it
• You want an Australian-made fridge — the Bushman Original SC35 (35L, $1,399) is AU-designed and built with a 7-year compressor warranty

Availability in Australia

The Kings 60L Stayzcool MKII is available at two primary retailers as of June 2026:

• Amazon AU — $699 RRP (model B0FKMWFDJF), generally in stock
• 4WD Supacentre — $699 RRP, available online + 50+ AU stores

The MKII is not available at Snowys Outdoors, BCF, or Anaconda (those retailers focus on the Dometic, Engel, and Bushman premium lines). The 4WD Supacentre retail footprint is the key advantage — warranty support and spare parts are easier to access than budget online-only brands.
