Zaptec

Connected directly to Joulo • charging sessions and kWh sync automatically, ERE is registered without manual work.

The people who use Joulo are an involved bunch. They follow the ERE scheme closely, connect their chargers themselves, and tell us straight what works and what does not • that feedback is how the product gets better. Maximaalski is one of them. He runs a Dutch YouTube channel and website about getting the most out of electric driving, recently paired a Zaptec Go 2 with Joulo, and shared his experience with us in his own words. Here is what stood out for him, with our notes on the details.

"I'm genuinely happy with how the platform looks, with the registration process, and with how easy my charger was to connect • no hassle at all. The clean overview really appeals to me, with the different forecasts of what the certificates will earn."

• Maximaalski (translated from Dutch)

He is an enthusiast, not on our payroll. Like any customer, he earns through the same referral program he can share with his own audience. More on that below.

A charger that connects in minutes

The Zaptec Go 2 is a good fit for what Joulo does. It has a built-in MID-certified energy meter, and that is the part that matters: for ERE registration the measurement has to happen inside the charger itself. A smart meter in your meter cupboard does not count. Maximaalski makes the same point in his guide, and it is worth repeating, because it is the single most common misunderstanding about earning from home charging.

Connecting is a one-time step. You create a free Joulo account, link your Zaptec account once, and from then on Joulo reads your charging sessions automatically through the Zaptec cloud. No photos, no CSV files, no quarterly admin round. Sessions from after 1 January 2026 (the official start of the scheme) are picked up too, even if they happened before you signed up.

A nice extra: the Go 2 is also V2G-prepared in hardware (bidirectional charging). For ERE today only charging counts, grid to car, but it is good hardware to grow into.

What he liked: the overview and the forecasts

The thing Maximaalski keeps coming back to is the calm, clear dashboard. Joulo shows three forecast scenarios, low, mid and high, so you see a realistic range of what your sessions might earn rather than one optimistic number. That honesty is deliberate: ERE prices are market-dependent, so we show a range and call it indicative, never a guarantee.

After that, there is almost nothing to do. Joulo checks and processes the sessions in the background and pays out every quarter. The contract is cancellable per year, so there is no long lock-in.

Charge smart, earn on the same kWh

Maximaalski also charges on a dynamic energy tariff, and that stacks neatly with ERE. With a dynamic-pricing provider like Tibber, one of Joulo's energy partners, you charge when power is at its cheapest and greenest. Joulo then earns ERE on every one of those same kWh. Cheaper power going in, ERE income coming back out, with no change to how you charge.

From viewer to referral

Maximaalski recommended the Zaptec Go 2 and Joulo combination on his channel based on his own experience, and the sign-ups are coming in through that video and his website. That is exactly how the referral program is meant to work.

Joulo's service fee is 20% as standard, and drops to as little as 10% through referrals. Every active referral lowers your own fee by one percentage point. So someone who genuinely likes the product, and whose audience signs up, ends up paying less themselves while their viewers start earning from charging they were already doing. No hype needed • just a real recommendation.

If his video or guide is what brought you here, sign up with his code JKNGF4 • joulo.nl/signup?ref=JKNGF4. It credits him as your referrer.

The honest numbers

These figures are indicative and move with the market. They assume Joulo's standard 20% fee.

Home charging	Indicative net ERE income
~200 kWh / month	around €245 per year
~400 kWh / month	around €555 per year
Per kWh (net)	roughly €0.13 to €0.17

Through referrals the fee can drop to 10%, which lifts those figures. Payouts land every quarter, and your first one includes any eligible sessions from earlier in the year.
