There is no standard number. How many EV chargers fit in a container depends on the carton each model ships in, how those cartons stack or palletise, and whether floor space or the weight limit runs out first. The reliable route is the factory’s packing list — carton dimensions, units per carton, gross weight per carton — then the layer maths and weight check below, before you book freight.
Key Takeaways
- There is no standard units-per-container figure; carton dimensions decide it.
- Run the maths in order: cartons per layer, layers, total, then the weight check.
- Palletising and mixed carton sizes both reduce the count — plan for them explicitly.
- Demand the packing list in the quotation and verify it at pre-shipment inspection.
Why No Catalogue Number Exists
A portable charger, a wallbox and a DC cabinet are three different loading problems, and carton size — not charger size — decides the count. Retail packaging can make the carton far larger than the unit inside. Two factories packing the same class of charger in different cartons give two different counts, and any figure quoted without carton data is a guess.
The Loading Maths, Step by Step
- Get the carton data in writing: carton length, width and height, units per carton, gross weight per carton.
- Cartons per layer. Divide the container’s internal floor length by carton length and floor width by carton width; round both down and multiply. Try both orientations.
- Layers. Divide internal height by carton height and round down — then check the factory’s stacking limit, since crush strength can cap layers earlier.
- Total cartons = cartons per layer × layers. Multiply by units per carton for the unit count.
- Weight check. Cartons × gross weight per carton, compared with the container’s payload, which varies by container and route — confirm it with your forwarder.
One hypothetical carton, worked through — it is not any product’s real packing figure:
| Step | Worked example (hypothetical carton) | What it tells you |
|---|---|---|
| Carton | 60 × 45 × 35 cm, 8 kg gross, one unit per carton | The input every later step depends on |
| Cartons per layer | 20 ft floor of about 5.9 × 2.35 m: 9 along the length × 5 across = 45 | Orientation matters; test both ways |
| Layers | Internal height about 2.39 m ÷ 0.35 m = 6 layers | Still subject to the carton’s stacking limit |
| Cartons per container | 45 × 6 = 270 cartons, so 270 units | A planning figure before any fit allowance |
| Weight check | 270 × 8 kg = 2,160 kg | For light products, space binds first |
What Changes the Count
Palletising. Pallets protect cartons and unload fast, but the pallet footprint consumes floor positions and its height consumes layers, so a palletised load holds less than a floor-loaded one. Decide from your warehouse handling; the choice changes the count you quote customers.
Mixed models. Compute each model’s cartons separately: different carton sizes rarely tessellate perfectly, so a mixed load lands below the single-model figure.
Extras. Holsters, brackets and spare cables shipped as separate cartons need their own lines: small individually, real across a full container.
Before You Book: The Packing Data to Demand
Put these in the quotation request, so freight quote and container plan rest on the same numbers:
- Carton dimensions, gross weight per carton and units per carton, per model.
- Whether accessories ship inside the unit carton or separately.
- The carton stacking limit, and the pallet plan if palletised.
- A loading plan for the first shipment of a new model.
Verify the same data at pre-shipment inspection, where cartons are counted and packing checked before sealing. Who arranges and pays for loading depends on your trade terms — our FOB vs DDP guide sets out where that responsibility sits.

For a container plan, send your models and quantities and ask for the packing list in the quotation — contact us before committing to a freight rate.
Frequently Asked Questions
How many portable EV chargers fit in a 20 ft container?
There is no fixed figure. With the hypothetical example carton above, the layer maths gives 270 cartons; your count follows your supplier’s carton dimensions, stacking limit and loading style.
Is floor loading or pallet loading better?
Floor loading fits more units; pallet loading unloads faster and protects cartons better. Choose from your warehouse equipment, and fix the choice before you calculate.
Who should calculate the load — the factory, the forwarder or me?
All three: the factory supplies the data, the forwarder plans the container, you check the plan against the packing list.
