Powerbuilt 3 Ton Unijack — All-in-One Bottle Jack & Jack Stand, 11–21 in Lift, Wide Base (Model 620471)

The Powerbuilt 3 Ton Unijack is an all-in-one vehicle lift that combines a 3,000 lb bottle jack and a ratcheting jack stand into a single heavy-duty unit for lifting and safely supporting cars, SUVs, trucks, RVs and trailers.

If you need a compact, multi-purpose lifting tool for maintenance, roadside repair or leveling, this Powerbuilt model 620471 merges speed and stability. Its integrated ratcheting safety bar locks the support at the chosen height so the jack both raises and holds the vehicle. A wide steel base reduces sinking on soft ground, making it practical for garages, driveways and outdoor use with larger vehicles.

How does this Unijack lift and secure a vehicle?

The unit uses a hydraulic bottle jack mechanism to raise the load and an internal ratcheting bar that functions as a built-in jack stand. Once you pump the handle to the desired height, the ratchet engages to hold the vehicle while you work — no separate stand needed. Release is controlled and gradual to lower the vehicle safely.

• 3-ton (6,000 lb) rated capacity for many light trucks and SUVs
• Lift range approximately 11" to 21" for common jacking points
• Hydraulic bottle jack action for fast lifting
• Ratcheting safety bar locks in the raised position

Is this Unijack stable enough for uneven or soft surfaces?

Yes — the wide steel base spreads the load, lowering ground pressure and reducing the chance of the jack sinking into soil or gravel. That makes it useful for RV leveling, trailers and off-road situations where surface firmness varies. For permanent or extended under-vehicle work, pair with wheel chocks and support stands following safe procedures.

• Large base footprint for improved stability
• Better performance on gravel, dirt and grassy surfaces
• Suitable for quick leveling tasks with RVs and trailers
• Follow vehicle manufacturer jacking points and safety steps

What vehicle types and tasks is this tool suited for?

The Powerbuilt 3 Ton Unijack is designed for light trucks, SUVs, vans, jeeps and many RV/trailer setups that fall within its lift and capacity range. Use it for routine tire changes, suspension work, emergency roadside lifting and minor underbody access. It’s compact enough for garage storage yet rugged enough for occasional outdoor use.

• Ideal for pickup trucks, SUVs and larger passenger vehicles
• Works for many trailers and small-to-medium RV support tasks
• Good for roadside tire changes and home maintenance
• Not intended as a substitute for full-size shop lifts for heavy commercial vehicles

How durable and safe is the Unijack over time?

Built to meet or exceed ANSI standards, the Unijack uses welded steel construction and quality hydraulic components for long-term use. Powerbuilt backs the product with a one-year factory warranty, and the ratcheting safety mechanism reduces the chance of accidental descent during work. Regular inspection and basic maintenance extend service life.

• ANSI-compliant design and load rating
• Welded steel base and lifting components for durability
• One-year manufacturer warranty from Powerbuilt
• Simple maintenance: keep hydraulic fluid at proper level and inspect for wear

Who is this for: The Powerbuilt 3 Ton Unijack fits DIYers, mobile mechanics and outdoor enthusiasts who want one compact tool to both lift and support mid-sized vehicles. It’s particularly useful for owners of pickups, SUVs, vans and small RVs who need a portable, stable lifting solution for tire changes, light repairs and leveling away from a full shop. Always use the Unijack on firm ground, follow vehicle jacking point guidance and combine with wheel chocks for safe operation.
