If you've been moving pallets by hand with a manual jack, switching to electric feels like a big upgrade. Then you start shopping and run into two machines that look a lot alike: the electric pallet jack and the electric pallet stacker. Both carry loads on forks. Both run on batteries. But they're built for different jobs, and buying the wrong one is a pricey mistake.
What each one does
An electric pallet jack is built to move pallets across a floor. It lifts the load just high enough to clear the ground, a few inches, and then you drive it where it needs to go. It's the workhorse for loading docks, trucks, and moving inventory from point A to point B.
An electric pallet stacker lifts loads up. It has a mast, like a small forklift, so you can pick a pallet off the floor and set it on a rack shelf. Our POLAR-LIFT stacker handles 3,300 pounds and lifts up to 10 feet.
The easiest way to think about it: a jack moves things sideways, and a stacker moves things up.
Questions to ask before you buy
Where do your pallets end up? If everything stays on the floor, or goes from a truck to a floor staging area, a pallet jack is all you need. If pallets go onto racking, you need a stacker. Trying to hand-unload a pallet onto a shelf every time is slow and hard on your crew's backs.
How far do you travel? Pallet jacks are lower, lighter, and usually quicker to move around. If your team is hauling pallets the length of a long warehouse all day, a jack will feel easier. Stackers are heavier because of the mast and are better suited to shorter runs near your racks.
How much room do you have? Stackers are taller and need more clearance overhead and in the aisles. Before you buy one, measure your aisle widths, door openings, and any low beams or sprinkler lines. Pallet jacks fit almost anywhere a pallet fits, including into the back of a trailer.
What are you lifting? Both of our POLAR-LIFT units are rated for 3,300 pounds, which covers most standard pallet loads. If you regularly handle heavier loads, talk to us before ordering. Running any machine near or over its rating wears it out faster and isn't safe.
What's your floor like? Both machines want a smooth, level surface. Cracked concrete, steep ramps, and gravel will slow you down and are hard on wheels. Stackers are less forgiving here, since a raised load on uneven ground can tip.
Why not just get a forklift?
For a lot of small and mid-sized operations, a full forklift is more than they need. Forklifts cost more, need more room to turn, and in many cases require operator certification. Walk-behind electric jacks and stackers are compact, easier to learn, and quiet enough to run indoors without exhaust. For a shop that stacks a few pallets a day, a stacker often does the job for a fraction of the cost.
Battery and charging
Our POLAR-LIFT pallet jack runs on a 48V lithium battery. Lithium charges faster than older lead-acid batteries, doesn't need watering, and handles quick top-up charges during breaks. If you run more than one shift, plan where the machine will charge and build that into your routine so it doesn't die halfway through an afternoon.
When it makes sense to have both
Plenty of warehouses end up with one of each. The jack handles dock work and long hauls across the floor, and the stacker stays near the racks to put pallets away and pull them down. If you're unloading trucks and stocking shelves every day, having both keeps one machine from becoming a bottleneck.
