Key Takeaways
- ARB CKMTA12 twin motor (~$599) is the best overall — 72 LPM, 100% duty cycle
- ARB CKMA12 single motor (~$449) is the smart solo choice — 42 LPM, 100% duty cycle
- 100% duty cycle is the key upgrade over all sub-$400 options — no rest breaks ever
- VIAIR 400P (~$349) remains the value pick if ARB is over budget
Under $650 covers the full range of our comparison including both ARB compressors — the CKMA12 single motor (~$449) and CKMTA12 twin motor (~$599). Adding ARB to the field is a qualitative step up: 100% duty cycle, proven 30-year reliability track record, and the most serviceable compressor brand in Australia. For anyone who tours regularly, does remote trips, or values having the best tool for the job, the ARB CKMA12 single motor at ~$449 is the clear buy. For groups, convoys, and maximum speed, the CKMTA12 twin motor at ~$599 is the professional choice. Both outperform everything in the under-$400 range on duty cycle — the most important spec for real-world touring.

ARB CKMTA12 Twin Motor Compressor
At a Glance
- Twin motor delivers 72 LPM — the fastest airing-up in our comparison
- 100% duty cycle means it never needs a rest break
- Extremely reliable — ARB's most popular compressor for 30+ years
- Stainless steel braided hose, quality fittings throughout
- Can be mounted under-bonnet or used as portable unit
- ARB dealer network means easy service and warranty support
- Most expensive compressor in the comparison at ~$599
- Draws ~47A peak — requires a healthy battery and decent cable

The ARB CKMTA12 is the benchmark 12V compressor for serious Australian 4WD touring. Twin motors, 72 LPM flow rate, 100% duty cycle — it can air up a full-sized 4WD in under 4 minutes without breaking a sweat. If you only buy one compressor, buy this one.

Mean Mother Adventurer 4
At a Glance
- 180 LPM flow rate is the fastest in the mid-range bracket
- Wireless 2.4 GHz remote lets you stand back from the tyre while airing up
- 5-year limited warranty — longest in its price class
- Choice Magazine rated for inflation and ease of use
- Includes carry bag, 5m rubber hose, and adaptor hose with bleed-off gauge
- Thermal cut-out and 45A circuit breaker protect the motor on long jobs
- Australian brand (Haigh Australia, QLD) with local support
- 8.7kg is heavy for a portable unit — not the pick for ultralight touring
- 45A peak current draw is the highest in this class — confirm your wiring can handle it
- Not a twin-motor unit — single cylinder means longer recovery after a thermal cut-out
- Remote battery is a 12V 23A cell, not a coin cell — slightly awkward to source
- Sits between budget compressors and twin-motor ARB in price without matching either's clear value proposition
The Mean Mother Adventurer 4 is the fastest single-cylinder 12V compressor you'll find in Australia for under $400. The 180 LPM flow rate, wireless remote, and 5-year warranty make it a genuine alternative to the ARB CKMA12 for solo 4WD tourers who don't need a twin motor. The trade-off is weight (8.7kg) and current draw (45A peak) — this is a unit for someone with a properly wired second battery, not a quick-clamp job from the start battery.

VIAIR 400P Portable Compressor
At a Glance
- 47 LPM flow rate is one of the fastest in the mid-range bracket
- 150 PSI maximum handles high-pressure tyres on larger 4WDs
- Popular and proven — large user community for advice and support
- Quality construction with metal fittings and braided hose
- Good value for the performance offered
- American brand — warranty support in Australia less convenient than ARB
- 33% duty cycle requires rest breaks on big airing-up jobs
- Slightly heavier than lightweight rivals
- Battery clamps rather than Anderson plug can be fiddly on some setups
The VIAIR 400P is a strong mid-range alternative to ARB for serious campers and 4WDers who want good flow rate and 150 PSI capability without the full ARB price. The American brand support is the main compromise vs the ARB CKMA12.

Kings 12V Air Compressor
At a Glance
- Cheapest compressor in our comparison at ~$129
- Very compact and light — easy to store in any vehicle
- Adequate for passenger car tyres and light off-road use
- Available from 4WD Supacentre stores nationwide
- 25 LPM flow rate is slow — airing up a 4WD takes 15+ minutes per tyre
- Lower 120 PSI max limits use with high-pressure tyres
- 20% duty cycle means long rest periods
- Not suitable for large 4WD tyres or regular off-road use
- Build quality and longevity below all rivals
The Kings 12V Compressor is fine for car tyres and the occasional light off-road trip when budget is the top priority. For any serious 4WD touring or regular use, spending more on an ARB or Bushranger will save time and frustration.

Frequently Asked Questions
+ Is the ARB CKMTA12 worth $250 more than the Bushranger?
For serious 4WD tourers, yes. The ARB CKMTA12 is 60% faster (72 vs 45 LPM), runs at 100% duty cycle (vs 33%), and is backed by ARB's national service network. Over 5+ years of regular use, the ARB's reliability and speed advantage pays for the premium. For occasional 4WDers doing 5-10 trips per year, the Bushranger is a reasonable saving.
+ ARB CKMA12 or CKMTA12 — which should I buy?
Get the CKMA12 (single motor) if you tour solo or in a pair, cost is a factor, and 42 LPM (5–7 minutes per tyre) is acceptable. Get the CKMTA12 (twin motor) if you tour in groups, value your time, or want maximum reliability for extended remote trips. Both have identical 100% duty cycle and quality — the only difference is flow rate and price.
