Here are the PowerX First charging fees:

**Charging rate (per kWh)**
- First members: **¥45/kWh~** at First eligible charging stations — always **¥20 off per kWh** compared to the regular rate of ¥65/kWh~ (/sources/en/reference/membership.md:47, :153).
- As a rough guide, that works out to about **45–55 yen/kWh** depending on the pricing menu (Economy/Regular/Premium), since general rates are 65/70/75 yen/kWh (/sources/en/runbooks/charging-use.md:248, /sources/en/runbooks/billing.md:46).

**Membership fee (billed separately from charging)**
- Annual Plan: **¥900/month** equivalent — 10,800 yen billed at enrollment and renewal (/sources/en/reference/membership.md:129, :193).
- Monthly Plan: **¥1,050/month** (/sources/en/reference/membership.md:129).
- A 90-day free trial is available, and there's no cancellation fee on the Annual Plan (though mid-term refunds aren't offered).

Note that the discounted First rate applies only at stations marked as First eligible (the red "F" sites on the map), and charging speed is the same regardless of membership.

**PowerX First member charging fees (per kWh, usage-based):**

- Economy: from ¥45/kWh
- Regular: from ¥50/kWh
- Premium: from ¥55/kWh

This is a ¥20/kWh discount versus regular (non-member) rates, which are Economy ¥65~, Regular ¥70~, Premium ¥75~ per kWh.

**Key points to keep in mind**

- Charging is always pay-as-you-go: the membership fee (¥900/month equivalent on the annual plan at ¥10,800/yr, or ¥1,050/month on the monthly plan, tax-inclusive) does **not** make charging free — you're billed per kWh each time.
- First pricing applies only at First-eligible charging stations. Some locations aren't covered, so a member can be charged a regular-tier rate (there are reported cases such as ¥75/kWh and ¥85/kWh at non-eligible sites).
- You pay for the electricity actually delivered, so the total depends on your vehicle and charging conditions; there's no separate per-minute charge in these rates.

Note: these figures come from the PowerX First membership page (captured 2026-08-17) and internal support guidance flagged as time-sensitive, so it's worth confirming the current rate in the app/at the station before relying on it.

PowerX First会員の充電料金は、充電メニューごとに次の単価（1kWhあたり、いずれも「〜」の最低価格）です。

- エコノミー：45円/kWh〜
- レギュラー：50円/kWh〜
- プレミアム：55円/kWh〜

一般利用が65円/kWh〜なので、いつでも1kWhあたり20円割引になる計算です（/sources/ja/runbooks/membership.md:186、/sources/ja/reference/membership.md:110-155）。

あわせてご注意いただきたい点

- 充電は会費とは別に従量課金です。会費（月払い1,050円／年払い10,800円＝月額換算900円）とは別に、充電した電力量に応じたFirst価格が都度請求されます（/sources/ja/public-help/articles/40049805074585.md:20-26）。
- 45円/kWh〜はFirst対象ステーションに限られます。対象外の拠点（例：Audi HUBは85円/kWhでの請求）もありますので、アプリの地図にある赤い「F」マークで対象ステーションをご確認ください（/sources/ja/reference/membership.md:186、/sources/ja/runbooks/stations.md:174）。
- 上記は時期により変動しうる情報です。実際のご請求額は拠点やメニューにより異なりますので、直近の料金はアプリのステーション詳細画面でもご確認ください。
