Prompt (en)

I'd like to confirm how the PowerX First 90-day free campaign works.

(1) Does “90 days free” mean that only the membership fee is waived and charging fees are billed separately, or is everything free for 90 days?
(2) Why was I charged a charging fee during the free period when the store told me it was free?
(3) How can I cancel my membership?
(4) Can I use the service immediately after joining?
(5) How can I check whether I am enrolled, delete only my registered credit card information, or completely delete my account?

Expected (en)

(1) The 90-day free campaign waives the PowerX First membership fee for 90 days. Charging itself is not free; if you use the charger, charging fees are billed separately based on the amount of electricity used.
(2) Charging fees still apply during the free period if you use the charger. If the information provided by the store differs from the actual pricing, we will check the situation with the store.
(3) To cancel, go to Account > PowerX First Management > Stop Automatic Renewal in the app. If you stop automatic renewal during the free period, you will not be charged a membership fee. You can continue using PowerX First until the expiry date even after stopping automatic renewal.
(4) You can use the service immediately after joining, but a reservation is required before charging.
(5) You can check your membership status under Account > PowerX First. If it shows “You are not currently a member,” no membership fee will be charged.
If you only want to delete your registered credit card information, please contact us. Our relevant department will handle the request.
To completely delete your account, go to Account > Settings > Delete Account. Please note that deleting your account will erase all registered information. Simply deleting the app does not delete your account or registered credit card information.

Output

Here's how the PowerX First 90-day free campaign works, based on the official Help Center article and our support guidance:

**(1) What "90 days free" covers**
Only the PowerX First membership fee is waived for 90 days — it is not "everything free." The official campaign article states that after the 90-day free trial ends, your registered credit card is charged according to the annual or monthly payment plan you selected at sign-up, and that if you charge during the campaign, PowerX First-priced charging fees are incurred separately (/sources/ja/public-help/articles/40050080640537.md:20-23). Note: customers who charged 2 or more times before November 18, 2024 are not eligible for the campaign (same article, line 25).

**(2) Why you were charged a charging fee during the "free" period**
That charge is expected. The campaign waives the membership fee only; charging fees (usage-based, at PowerX First member rates) still apply each time you charge. If a store told you everything was free, that was a miscommunication on the store's side — in similar cases we have confirmed the situation with the store directly (/sources/en/runbooks/membership.md:134-138). I'm sorry for the confusion. If you'd like, we can look into the specific billing amount with you.

**(3) How to cancel**
In the PowerX app, go to Account > PowerX First management screen > Stop automatic renewal (/sources/en/runbooks/membership.md:294-298). If you stop auto-renewal within the 90-day free period, no membership fee is charged at all. You can keep using the service until the contract end date, and rejoining later is possible. Simply uninstalling the app does not cancel anything.

**(4) Can you use it immediately after joining?**
Yes — once your app registration is complete, you can use it right away. Please note that a reservation is required to charge, so book a slot in the app before visiting a station (/sources/en/runbooks/membership.md:134-138).

**(5) Checking enrollment, deleting your card, or deleting your account**
- Check enrollment: App > Account > PowerX First. It shows "Currently enrolled" or "Not currently enrolled" (/sources/en/runbooks/membership.md:266). Under Account > PowerX First > Check payment plan, an active trial shows "90-day free trial active" in green next to your membership (/sources/en/runbooks/charging-troubleshooting.md:374-378).
- Delete only your registered credit card: this is handled by the relevant department rather than self-service in the app, so please contact support with your user details (/sources/en/runbooks/membership.md:44-48).
- Delete your entire account: App > Account > Settings > Delete Account. This erases all your information, including card details. Deleting the app alone leaves your user info (including card details) in place, so use the account deletion procedure for a complete deletion (/sources/en/runbooks/membership.md:294-298).

If you'd like, I can also help you verify your current enrollment status or look into the charging fee you were billed — just let me know.

Output

**What "90 days free" covers**
The campaign waives only the PowerX First membership fee (¥900/month annually or ¥1,050/month monthly) for 90 days; charging fees still apply.

**Why a charging fee appeared during the free period**
Charging fees are separate from the membership fee and apply to all usage. Additionally, first-member rates (¥45–55/kWh) apply only at stations marked with a red "F" on the map; non-eligible sites charge regular rates (e.g., ¥75/kWh).

**How to cancel membership**
Cancel via the app or contact customer support.

**Usage immediately after joining**
You can use the service immediately upon successful enrollment.

**Checking enrollment, deleting payment info, or deleting account**
Check enrollment status in the app’s member section. To remove credit card details, edit your payment methods in the app settings. For full account deletion, contact customer support directly.
