Which power station should you choose? The complete guide from 200Wh to 1000Wh

Are you hesitating between a small, compact battery and a large generator? At HelioPack , we receive questions every day about the "true" capacity of power stations. To help you make the right choice, here's our guide to selecting the ideal power output for your lifestyle.

1. Essential reminder: Watts (W) vs Watt-hours (Wh)

Before making your choice, keep this rule in mind:

  • Watts (W) = Instantaneous power. It's the "muscle". If your device requires 800W, your station must be able to deliver at least 800W.

  • Watt-hours (Wh) = Energy reserve. This is the autonomy. The higher this number, the longer you can use your devices.

2. Comparison: Which capacity for which use?

4. Why connect your station to a solar panel?

Having a large capacity (1000Wh) is good, but being able to fill it for free thanks to the sun is better!

  • For a 200Wh station, our 60W foldable solar panel is more than sufficient.

  • For a 500Wh to 1000Wh station, we recommend our 120W or 200W panels to ensure a full recharge in a single day of sunshine.

HelioPack Tip: If you are travelling between Europe (220V) and the USA (110V), make sure that your station accepts both input voltages for mains charging!

Conclusion: So, which one to choose?

  • Want something lightweight ? Stick with the 200Wh .

  • Want comfort while camping? The 500Wh is your best friend.

  • Do you want total independence ? Upgrade to the 1000Wh .
