EcoFlow generators have become one of the most sought-after options for those looking to address power outages in Cuba or send an energy solution to relatives on the Island. However, before purchasing one, there is something important to consider: not all EcoFlow models serve the same purpose, and making the wrong choice could mean spending a lot of money only to end up disappointed.
In this guide, we clearly and simply explain what the numbers mean, what can truly power an EcoFlow, and what you should keep in mind before sending it to Cuba.
First, the basics: EcoFlow does not "produce" energy; it stores it
Although many refer to them as "generators," EcoFlow devices do not generate electricity on their own. They are large batteries that can be charged from the grid or with solar panels. They then supply that energy when there is no power available.
Think of an EcoFlow as a water tank: if you don’t fill it up beforehand, there’s no water to draw from.
Capacity (Wh): how many hours the power lasts you
Capacity is measured in Wh (watt-hours) and is the most important figure. It literally indicates how much energy it can hold.
- 1000 Wh ≈ energy for a few hours
- 2000 Wh ≈ twice the time
- 4000 Wh or more ≈ many hours or even days, depending on consumption
Real example in Cuba:
Fan + bulb + TV = about 150–200 W. With a 1000 Wh EcoFlow → between 4 and 6 hours. A 2000 Wh one → between 8 and 12 hours.
Simple rule: If the blackouts are long, you need more watt-hours, not more power.
Power (W): which devices can you connect
Power, measured in W (watts), indicates how strong the devices you connect at the same time can be. It’s not about duration; it’s about strength.
Approximate consumption of common equipment in Cuba
- LED Bulb: 10 W
- TV: 80–120 W
- Fan: 60–100 W
- Refrigerator: 120–200 W (peak on startup)
- Microwave: 1000–1500 W
- Air conditioning: 1500–2500 W
Key rule: The total power of the devices cannot exceed that of the EcoFlow.
X-Boost: why some devices “start” even when they require more power. EcoFlow includes a feature called X-Boost that allows demanding devices to be used for short periods. It helps with: Microwaves, Coffee makers, Hair dryers, Some tools. It does not turn a small EcoFlow into a large one. It is not ideal for equipment that runs for many consecutive hours.
Expandable batteries: key to long power outages
Some EcoFlow models allow for the addition of external batteries, significantly extending their runtime. This is especially important in Cuba because power outages can last 10, 12 hours or more. Sometimes there isn't enough time to recharge. If the budget allows, an expandable EcoFlow is a great advantage.
Solar panels: almost mandatory in Cuba
Sending an EcoFlow to Cuba without solar panels is a common mistake. Why? There isn't always electricity to recharge it. Sometimes the power comes back for only a few hours. The sun is more reliable than the electrical schedule. Practical tip: An EcoFlow with solar panels is worth double. Even a small panel helps to stretch the energy

Common mistakes when buying an EcoFlow for Cuba
- To think only about power and not about duration
- Do not include solar panels
- Buy one very small "to save."
- To believe that it completely replaces the current without planning
Conclusion: what to check before sending it to Cuba
Before buying, ask yourself:
- How many hours do the power outages last?
- Which equipment do I definitely want to support?
- Do I have solar panels?
- Do I want something for now or for several years?
A well-chosen EcoFlow changes your life during power outages. A poorly chosen one does not.
For those who have already decided to take the step, Envíos23 offers the entire range of EcoFlow generators, from the most compact models to higher-capacity solutions for prolonged outages. Through this platform, it is possible to purchase and send EcoFlow directly to Cuba, with options tailored to different needs and budgets, thus making it easier for families on the Island to have a reliable source of energy amidst the power outages.
