General information

Our small, light & flexible energy provider
Do you want to spend a nice time outdoors, mobile, flexible and independently, without losing the comfort of light, communication, media and much more? Without having to put up with the noise, the smell of gasoline and the extra weight of a conventional power generator?
With the new energy storage range from ENERpower you can satisfy your thirst for energy almost everywhere, almost at any time and in almost any situation.

For each model we offer two versions:

  • Outdoor (Type 1): This version has been designed for outdoor and camping use

Important Features

Some important features make our product clearly superior to similar products:

  • 24V operating voltage: The special feature of our system is the very high operating voltage of 24V (7S). With this, our energy storage is much more robust and does not lose tension with high power consumption. Our product does not step-up, only step-down. The use of external converters 24V to 220V is possible and economical compared to 12V systems.
  • Weight: The ECD-500 is much lighter (only about 3.4 Kg.) than competitors' products, and that's due to the energy density of the Samsung SDI type INR18650-35E Li-Ion battery cells we use.
  • Design: In our product, we take into account the exact number of possible outputs (5V socket, 12V output, 24V output), so that enough power comes out of these outputs. This results in a fairly low self-consumption (3.5W) and very low self-discharge (about 3% per month in off-mode)
  • Made-in-Germany: Our product is made in Germany. The ECD-500 is NOT a stock product, and is made fresh accordingly. Furthermore, you will get a transparent overview of all technical data from us.

With our storage solutions you can spend time outside with the comforts of your own home. Our flexible energy storage offers you the benefits of Li-Ion technology with high energy density, light weight and total silence.
