Yes — as a general (non-member) user, you only pay for the electricity you actually charge.

- There is no membership fee for general use; billing is usage-based (pay-per-kWh), so your cost is simply the amount of energy (kWh) delivered × the unit rate for your plan. The official Help Center states: "For general use, no membership fee is charged and you are billed on a usage-based (pay-per-kWh) basis" (/sources/ja/public-help/articles/40049696828569.md:20, updated 2025-03-21).
- This also applies if you stop charging partway — you're billed only for the kWh actually delivered, not for the full reserved time (/sources/en/runbooks/billing.md, CS-141).
- One thing to expect: when you make a reservation, a temporary card authorization hold may appear on your card statement. That's not an actual charge — only the real charging amount is settled afterward (/sources/en/runbooks/billing.md, CS-052).

If you'd like a lower per-kWh rate, the optional PowerX First membership offers discounted charging, but it's entirely optional.

はい、その通りです。

一般利用（PowerX Firstに未加入）の場合、会費は発生せず、実際に充電した電力量に応じた従量課金制でお支払いいただく形になります（/sources/ja/public-help/articles/40049696828569.md:20、/sources/ja/public-help/articles/40047041357337.md:22）。

補足として、以下の点もあわせてご案内いたします。

- 料金は「充電した電力量（kWh）× 単価」で決まり、時間制ではありません。途中で充電を止めた場合も、その時点までに充電した電力量分の料金となります。
- 一般会員の充電単価はメニューにより異なり、1kWhあたりEconomy 65円／Regular 70円／Premium 75円です（時期により変更される場合があります）。
- 予約時にクレジットカードの与信（事前承認）が確保されることがありますが、これは実際の請求ではなく、充電終了後に実費で精算されます。

Output

Yes — as a general (non‑First) user, PowerX is pay‑as‑you‑go: you're charged only for the energy you actually charge, based on kWh, with no membership or monthly fee.

Key points:
- **No membership fee for general use.** App + credit‑card registration is required, and both reserving and charging are free of any subscription charge. (en/runbooks/membership.md:154, en/runbooks/compatibility.md:109)
- **Billed per kWh, not per minute.** PowerX uses volume‑based billing — you pay for the amount of energy delivered, not the time spent — so a slow charge doesn't cost you extra in time charges. (en/runbooks/billing.md:193, en/runbooks/charging-troubleshooting.md:460)
- **General-user rate:** ¥65/kWh and up, with the pricing menu at ¥65 / ¥70 / ¥75 per kWh (Economy / Regular / Premium). Each session is billed separately to your registered credit card, and the closing date depends on your card company. (en/runbooks/billing.md:37‑45)
- **What general users don't get:** advance booking (general users can reserve from about 30 minutes ahead, day‑of only, 30‑minute slots) and the discounted rate. PowerX First is optional and costs ¥1,050/month (or ¥10,800/year ≈ ¥900/month) for ¥45/kWh~, 3‑day‑ahead reservations, and 75‑minute slots. (en/reference/membership.md:110‑160, en/runbooks/charging-use.md:248)
- Charging output is the same for everyone (up to 150 kW, some stations capped at 120 kW) — membership only changes price and booking, not speed. (en/runbooks/compatibility.md:139)

One caveat: the per‑kWh figures above come from QA guidance last reviewed 2026‑08‑17 and are flagged as time‑sensitive, so please check the current pricing page for exact numbers: https://support-evcs.power-x.jp/hc/ja/articles/40049805074585

はい、一般利用は会費なしで、充電した電力量に応じた従量課金のみでのお支払いになります（/sources/ja/public-help/articles/40047041357337.md:22、/sources/ja/public-help/articles/40049696828569.md:20）。2024年11月18日以降、充電料金はすべて従量課金制です（/sources/ja/public-help/articles/26574552466457.md:20）。

あわせて、実際のご請求について几点ご案内します。

- 1kWhあたりの単価はステーションごとに異なり、アプリ内でご確認いただけます（/sources/ja/public-help/articles/26574552466457.md:24）。
- 予約確定時にクレジットカードの与信枠を一時的に確保し（オーソリ）、予約時間が終了して充電料金が確定した後、実際にかかった分だけを決済し、残りは返金されます。この処理は予約時間終了後1時間以内が目安です。カード会社から通知が届いても請求はされていないケースですのでご安心ください（/sources/ja/public-help/articles/24625279158553.md:20-42）。
- 予約時間終了後の超過料金は、現時点では発生いたしません（/sources/ja/public-help/articles/28501958588313.md:20）。
- 一方、予約開始時間・充電開始時間を過ぎてキャンセルした場合、または予約終了時間までにご利用がなかった場合は、キャンセルポリシーが適用され500円が発生します（/sources/ja/public-help/articles/16819739268249.md:30-33）。
- 駐車料金は原則お客様負担です（一部無料のステーションあり）。施設のご案内や看板でご確認ください（/sources/ja/public-help/articles/22881312858393.md:20-22）。
- なお、アプリの利用自体には会員登録が必要です。会員登録後にPowerX Firstに入会せず「一般利用」をお選びいただければ、会費は発生しません（/sources/ja/public-help/articles/24098543153433.md:25、/sources/ja/public-help/articles/40049728506393.md:22）。

つまり、基本的には「充電した分だけ」で問題ありませんが、上記のキャンセル料や駐車料金は別途ご負担となり得る点だけご注意ください。
