Sorry for the trouble — here's what's going on and how to fix it.

**Why the booking error happens:** When the charger is used back-to-back, the charging gun can overheat, which temporarily blocks both charging and new bookings. This is a known cause of errors when trying to book an additional 30-minute slot right after a session (/sources/en/runbooks/reservations.md:179-185).

**What to do:**
1. **Wait about 10–15 minutes** to let the charging gun cool down, then try booking the additional slot again.
2. **For the frozen phone/app:** force-close the app and restart it. If the whole phone is unresponsive, restart the phone itself, then reopen the app.

A couple of related notes:
- If you saw a **yellow LED** on the charger at any point, that also indicates the gun overheated — it resumes normally once it cools down (/sources/en/runbooks/reservations.md:187-195).
- You're only billed for the electricity you actually charged, so the failed booking attempt won't result in extra charges.

If the error still appears after waiting 15+ minutes and restarting the app, please let us know which station you're at and we'll look into it further.

ご不便をおかけして申し訳ございません。この症状には心当たりのあるケースです。

連続して充電をご利用いただいた場合、充電ガン（充電器）が過熱し、保護機能が働いて一時的に充電や予約ができなくなることがあります。追加予約枠でエラーが出る場合、この過熱による一時的な利用制限の可能性が高いです。

以下をお試しください。

1. **10〜15分ほど時間を空けてお待ちください** — 充電器がクールダウンし、過熱が収まると再び予約・充電できるようになります。
2. **アプリを再起動してください** — スマホのアプリがフリーズしている場合は、アプリを完全に終了してから再度起動してください。端末自体の再起動も有効です。
3. その後、改めて追加予約をお試しください。

なお、クールダウン待ちで予約枠をまたいでしまっても、料金は実際に充電した電力量に応じた従量課金ですので、余分な請求は発生しません。

上記をお試ししても解決しない場合は、恐れ入りますがアプリのお問い合わせフォームまたはサポートまで、ステーション名・時間帯・エラーの表示内容をお知らせください。個別に確認いたします。

Here's what's most likely happening and what to do.

Most likely cause: the charging gun has overheated from continuous use. When that happens, PowerX temporarily blocks both charging and new bookings, which shows up as an error when you try to add another slot. The same condition usually shows as a yellow LED on the charger.

Steps to try:
- Wait about 10–15 minutes for the gun to cool down, then try the additional booking again.
- Restart the PowerX app if it froze, then reopen it and check the reservation screen.
- If you are mid-session, note that charges are billed cumulatively (pay-as-you-go), so a stop-and-rebook does not lose what you already charged.

One important limit to check: general (non-member) use is capped at 30 minutes per reservation, and only PowerX First members can book longer slots (30/45/60/75 minutes, up to 75 minutes). So if you are using the service as a general user, an extra 30-minute slot may simply not be bookable rather than being a fault. This is from the official help article "最大何分まで充電が可能ですか？" (updated 2026-07-03): /sources/ja/public-help/articles/23458619608857.md:22-27.

Where this comes from, and one caveat:
- The cool-down/restart guidance is from our internal QA runbook entry CS-048: /sources/en/runbooks/reservations.md:179-185. That entry is flagged as time-sensitive, so treat the 10–15 minute figure as operational guidance rather than a published policy.
- The 30-minute vs 75-minute limits are from the official public Help Center article cited above.

I can't extend, cancel, or force a reservation myself. If it still errors after cooling down and restarting the app, send me:
- Station name, date and time, and charger number
- The exact error message shown (or a screenshot)
- Whether the charger LED was yellow

With those details I can route it for investigation.

ご不便をおかけして申し訳ございません。

まずアプリのフリーズについては、一度アプリを終了して再起動してください。そのうえで、時間を10〜15分ほど空けてから再度ご予約をお試しください。連続してご利用いただいた場合に充電ガンが過熱し、一時的に充電・予約ができなくなることがあり、クールダウンで解消するケースがあります（/sources/ja/runbooks/reservations.md:179-183）。なお、この案内は時期に依存する運用情報を含むため、公式の最新案内と食い違いがないかあわせてご確認ください。

公式ヘルプでは、予約不可になる理由として以下が案内されています。

- 施設先の営業時間外・定休日が選択されている
- 充電準備中
- メンテナンス中
- 他のお客様が既にご予約またはご利用中

タイムバーと「予約へ進む」ボタンがグレーになっている場合は、その時間帯は予約できない状態を示しています（/sources/ja/public-help/articles/26341574195865.md:20-32）。

また、充電のご利用が続いて充電器内蔵の蓄電池残量が低下した場合は、電力量を蓄えるために予約できない期間が設けられることがあります。加えて、設備保護のために予約の前後に冷却時間が設けられる場合もあります（/sources/ja/public-help/articles/26341574195865.md:55-59）。そのため、クールダウン後に空き状況をご確認のうえ、少し後の枠をお試しいただくのがよいかと思います。

予約の取消や延長などの操作をこちらで代行することはできません。時間を空けてもエラーが繰り返し表示される場合は、対象ステーション名、日時、表示されたエラーメッセージ（可能であれば画面キャプチャ）をお知らせください。内容を確認のうえ、サポート窓口への引き継ぎをご案内します。
