No, you don't need a paid membership. PowerX First is an optional paid plan — general (non-member) users can charge too (/sources/en/runbooks/charging-use.md:192).

Here's what first-time use looks like:

**What you do need**
- The PowerX app and a registered credit card. Charging is pay-as-you-go, so there's no membership fee for general use — you're only billed for the electricity you actually use (/sources/en/runbooks/membership.md, CS-106).

**As a general user**
- Rates are from ¥65/kWh (Economy), ¥70 (Regular), ¥75 (Premium), billed by actual kWh used (/sources/en/runbooks/charging-use.md, CS-025).
- Reservations can be made from 30 minutes before use, and time slots are up to 30 minutes (/sources/en/reference/membership.md:133).

**If you want PowerX First (optional)**
- From ¥900/month on the annual plan (¥1,050/month on the monthly plan), it lowers charging to from ¥45/kWh, lets you book up to 3 days ahead, and extends slots to 75 minutes (/sources/en/reference/membership.md:129).
- There's also a 90-day free trial for first-time members, and if you stop auto-renewal within that period, no membership fee is charged (/sources/en/reference/membership.md:209).

So feel free to start with general use and see how it fits your routine — you can always join First later if you charge often.

いいえ、有料会員にならなくてもご利用いただけます。

PowerXアプリでは、会費の不要な「一般利用」が用意されており、PowerX First（有料会員）にご登録いただかない限り会費は発生しません（/sources/ja/public-help/articles/38947879238169.md:24-26）。一般利用は会費なしで、充電した分だけの従量課金（一般価格 65円/kWh〜）でご利用いただけます（/sources/ja/public-help/articles/40047041357337.md:20-22）。

ただし、一般利用の場合も以下の点にご注意ください。

- PowerXアプリへの登録とクレジットカード登録が必要です（予約・充電ともにアプリから行います）。
- 予約は利用当日の30分前から、利用時間は最大30分です。
- 充電料金は一般価格（65円/kWh〜）がかかります。

なお、有料の「PowerX First」（月払い1,050円／年払いで月額900円換算）にご入会いただくと、First対象ステーションで45円/kWh〜の優待料金、3日前からの予約、最大75分の利用などの特典があります。初めての方は90日間の無料体験もあり、無料期間内に自動更新を停止すれば会費は発生しません（充電料金自体は別途かかります）。

まずは一般利用でお試しいただき、利用頻度に応じてFirstの入会をご検討いただくのもよいかと思います。

No — a paid membership is not required. You can use PowerX as a general (non-member) user and just pay for the electricity you actually charge.

What you do need (free to sign up):
- Download the PowerX app (App Store / Google Play).
- Register an account: phone number + SMS verification code, set a secret question, and register a credit card. Registration takes about 30 seconds, and the app is usable right after. (/sources/ja/public-help/articles/24098543153433.md:25)
- Make a reservation in the app before going to the station, then scan the QR code shown in the app at the charger, plug in, and press start. Charging ends when you press "Charge Stop" or your reserved time ends. (/sources/ja/public-help/articles/24098543153433.md:29)

How general use differs from the paid PowerX First membership:
- Billing: pay-per-use (usage-based) either way — there is no membership fee for general use. (/sources/ja/public-help/articles/24098543153433.md:35, /sources/en/runbooks/membership.md:154)
- Session length: general users can book up to 30 minutes; First members can book up to 75 minutes (30/45/60/75-minute slots). (/sources/ja/public-help/articles/23458619608857.md:20)
- Booking window: First members can reserve from 3 days ahead; general users from 30 minutes before use. (/sources/en/runbooks/membership.md:154)
- Price: First lowers the per-kWh rate (rough guide from our operational notes: about ¥65–75/kWh general vs ¥45–55/kWh First). Treat these as approximate — check the exact rate shown in the app for the station you plan to use. (/sources/en/runbooks/charging-use.md:248)

Note on the free trial: there is a PowerX First 90-day free campaign — it waives the membership fee for 90 days, but charging fees still apply, and it auto-renews to the paid annual/monthly plan you selected unless you turn off auto-renewal in the app during the trial. If you stop auto-renewal within the trial, no membership fee is charged. (/sources/ja/public-help/articles/40050080640537.md:20) Availability of this campaign can change, so confirm it in the app before signing up.

Also worth knowing: parking at a station is usually charged separately by the facility, so that is not covered by either option. (/sources/ja/public-help/articles/22881312858393.md:22)

If you tell me which area you'll be charging in, I can help you check stations and the current rates shown for them.

いいえ、有料会員（PowerX First）にご登録いただかなくてもご利用いただけます。

PowerXアプリは「一般利用」として、会費なし・充電した電力量に応じた従量課金（65円/kWh〜）で利用できます。アプリの会員登録自体は無料で、電話番号のSMS認証とクレジットカード情報の登録だけで約30秒で完了し、すぐ使えます（/sources/ja/public-help/articles/24098543153433.md:25、/sources/ja/public-help/articles/38947879238169.md:22）。

一般利用とPowerX Firstの主な違いは次のとおりです。
・充電料金：一般利用 65円/kWh〜 ／ First 45円/kWh〜（First対象ステーションに限る）
・予約受付：一般利用は当日30分前まで ／ Firstは3日前から（一部ステーションを除く）
・利用時間：一般利用は30分間のみ ／ Firstは最大75分（一部ステーションを除く）
・充電速度：いずれも最大150kW（120kWに制限しているステーションあり）
・会費：一般利用 なし ／ First 月額900円（年払い一括10,800円の場合の月あたり）、月払いは1,050円（/sources/ja/reference/membership.md:203付近の比較表）

なお、Firstには90日間無料キャンペーンがあり、無料期間中にアプリから「自動更新を停止」すれば会費は発生せず退会できます。停止しないと無料期間終了後に登録済みカードで決済されます（/sources/ja/public-help/articles/40050080640537.md:20-25）。また、過去の無料充電キャンペーン終了後も、ご自身で申し込まない限り会費制へ自動的に移行されることはありません（/sources/ja/public-help/articles/38947879238169.md:40）。

まずは無料で会員登録して一般利用で試し、利用頻度が高い場合にFirstをご検討いただく流れが安心です。
