What data your shipping agency needs for your power station

Before requesting a quote to ship a power station meant for the next outage, your agency is going to ask for specific data — not the model's commercial name, but the figures that determine how it's shipped. This page doesn't tell you which agency to use or how easy it is to ship a unit: that depends on rules that change without notice, and an outdated recommendation can cost you real money if you follow it to the letter. What you can take from here is the objective data any serious agency is going to ask for, taken straight from each product's real spec sheet in this catalog.

1. Capacity in Wh (not Ah, not mAh)

A battery's capacity is stated in watt-hours (Wh) — it's the figure that determines whether a unit falls within the air-shipping limit for lithium batteries (IATA sets the threshold at 100Wh without special authorization, and 160Wh with it). The EcoFlow RIVER 2 has 256Wh; the EcoFlow DELTA Pro Ultra has 6144Wh — the difference between those two numbers is the difference between a simple process and one that requires a special declaration. Each product's spec sheet on this site shows capacity in Wh directly, with nothing for you to convert.

2. Battery chemistry

Not every lithium battery is regulated the same way. The exact chemistry — LiFePO4 (lithium iron phosphate), standard lithium-ion, or another — is a figure your agency needs to classify the shipment, and one chemistry isn't the same as another in terms of thermal stability. The EcoFlow DELTA 3 and the EcoFlow DELTA Pro, for example, use LiFePO4 (LFP); it's stated on each product's spec sheet in this catalog, you don't have to assume it from the brand.

3. Real weight, not the box's weight

The weight an agency quotes is the unit's, not a generic box for that category. Here's the real range: the EcoFlow RIVER 2 weighs 3.50 kg; the EcoFlow DELTA Pro weighs 44.90 kg — almost 13 times more. Confirm it on the spec sheet for the exact model you're going to buy, not the approximate weight you remember from a similar one.

4. The unit's dimensions, not a similar model's

When a product's spec sheet states dimensions, it's the figure the agency uses to calculate volumetric weight — sometimes more decisive than real weight in the final shipping price. The EcoFlow DELTA Pro, for example, measures 25 x 11.2 x 16.4 inches per its spec sheet. Not every product in the catalog states this figure: when it's not on the spec sheet, it's worth asking the seller directly before getting a quote, instead of estimating it from the product category.

5. Exact model, with the full name

"An EcoFlow station" isn't enough — there are eight different models in this catalog, with capacities ranging from 256Wh to 6144Wh. The model's full name (not just the brand) is the data that avoids a miscalculated quote from confusing an EcoFlow RIVER 2 with an EcoFlow DELTA Pro Ultra. The comparator page shows each model's full name side by side, handy for copying it exactly before writing to your agency.

6. If you buy more than one unit, the weight adds up

A power station for a long outage almost never ships alone: it usually comes with an extra battery or a solar panel, and the agency quotes the full package, not each piece separately. The EcoFlow DELTA 3 weighs 12.50 kg; adding the EcoFlow Bateria Extra Serie DELTA 3 1024Wh (12.50 kg) practically doubles the shipping weight, even though the final capacity also doubles. A EcoFlow Panel Solar 220W Bifacial adds 7.00 kg more if bought alongside it. None of these combos show up as a single product on the individual spec sheet: if you're going to order more than one item, add each one's weight separately for your agency, not just the main station's.

Where to find all this data together

Every product sheet in this catalog has the data on the same page — capacity, chemistry, weight, dimensions when the manufacturer states them, and the model's full name — taken from the real technical spec, never estimated. If you also need to calculate how long that unit will last with your specific devices before deciding which to buy, the runtime calculator runs that number against the real catalog.

What this page does NOT cover

This guide doesn't say whether your specific shipment will go through without a problem, how much it will cost you, or how long it will take — those three things depend on the agency, the moment, and customs rules that change without prior notice, and publishing them here as if they were fixed would be false information from the day it was written. It also doesn't suggest declaring less than the real figures to cut shipping cost: the capacity, weight and chemistry you declare have to match the unit's real spec sheet, because an incorrect declaration for a lithium battery is the kind of mistake an agency can reject on the spot, or worse, let through and turn into a problem at customs on arrival. This page's only job is to gather, in one place, the objective data that comes from each product's real spec sheet — the rest of the decision is yours and your agency's.

About the agencies themselves

This site doesn't handle shipments or earn a commission from any agency — our published methodology explains why. As a neutral starting point, agencies with active shipping include Cubamax and Cuballama — verified active at the time of writing, listed alphabetically, with no implication that one is better than the other. Each agency has its own rules for weight, packaging and documentation for lithium batteries, and those rules change: confirm them directly with the agency before buying, not with this page.
