Output

Here's what the official PowerX sources say:

**Maximum output**
- Max output is 150 kW when using one connector, and 120 kW when two connectors are charging two vehicles at the same time (/sources/ja/public-help/articles/23123162280473.md:20).
- Note that a few stations are currently capped at 120 kW and are being updated to 150 kW across all locations (/sources/ja/public-help/articles/40049220868505.md:20-22).

**Does your plan or PowerX First membership change the output?**
- No. PowerX First does not change charging speed — there is no speed difference, and all stations offer up to 150 kW ultra-fast charging regardless of membership (/sources/ja/public-help/articles/40049220868505.md:20).
- Likewise, the pricing menu you choose (Economy / Regular / Premium) does not affect charging speed; those menus differ only in renewable-energy ratio and price, not output (/sources/en/runbooks/compatibility.md CS-112).

**Why you might see less than the maximum in practice**
Actual output can be lower than the listed maximum because of conditions such as outside air temperature, the charger's own temperature (the charger applies an automatic output limit), and your vehicle's power-acceptance capacity, battery temperature, and battery level (/sources/ja/public-help/articles/23459356662809.md:20, /sources/ja/public-help/articles/23123162280473.md:21).

So in short: up to 150 kW (120 kW when two cars charge simultaneously, and at some not-yet-upgraded stations), and neither PowerX First nor your pricing plan raises or lowers that limit.

Output

最大出力とプランによる制限の有無について、以下のとおりご案内します。

## 最大出力

- **1口利用の場合：最大150kW**
- **2口（2台同時充電）の場合：最大120kW**

（公式ヘルプ「充電出力はどのくらいですか？」 /sources/ja/public-help/articles/23123162280473.md:20）

## プランやPowerX Firstによる出力の制限

**ありません。** 充電スピード（出力）は会員種別（PowerX First／一般）や料金メニュー（Economy／Regular／Premium）によって変わらず、すべて共通です。メニューの違いは再生可能エネルギーの比率と料金のみで、充電速度には影響しません（/sources/ja/runbooks/compatibility.md:139、/sources/ja/runbooks/charging-use.md:27）。

## 出力が変動する要因

最大出力に達しない場合は、以下のような要因が考えられます。

- 外気温や充電器本体の温度による自動的な出力制限
- お車の受電容量（車種による差）
- バッテリー残量（SOC）の上昇に伴う出力低下（一般的な挙動です）

また、一部のステーションでは現在最大出力が120kWに制限されていますが、順次全拠点150kWへのアップデートが予定されています（/sources/ja/reference/membership.md:189）。

詳しくは公式ヘルプをご参照ください。

Output

**Maximum output: 150 kW** — with a couple of conditions, and no, your plan or PowerX First membership does not change it.

**Output limits that do apply**
- **150 kW** when a single port is in use; **120 kW** when two ports are charging simultaneously (en/runbooks/charging-use.md:27, en/runbooks/compatibility.md:95).
- Some stations are currently capped at **120 kW** maximum, with all locations to be upgraded to 150 kW in due course (en/reference/membership.md:195).
- Output can be **automatically limited** by ambient temperature and charger temperature, and it also depends on how much power your vehicle can accept — so the maximum may not be reached depending on vehicle and conditions (en/runbooks/charging-use.md:27).
- Output naturally **declines as state of charge (SOC) rises**; that is normal behavior (en/runbooks/charging-troubleshooting.md:460).

**Plan / membership impact**
- Output **does not vary by plan or membership type** — PowerX First and general members get the same maximum output (en/runbooks/charging-use.md:27, en/runbooks/charging-troubleshooting.md:460).
- The pricing menu you choose (**Economy / Regular / Premium**) also does not change charging speed; those menus differ only in renewable-energy ratio and price (en/runbooks/compatibility.md:139).
- PowerX First benefits are on the pricing and reservation side instead: discounted per-kWh rate, booking from 3 days ahead, and longer reservation slots (up to 75 min vs. 30 min for general users) (en/runbooks/charging-use.md:248).
- Billing is per kWh charged, not by time, so lower output does not put you at a time-based disadvantage (en/runbooks/charging-troubleshooting.md:460).

If your actual output is well below these figures (e.g. 20–30 kW), that is usually temperature derating or the vehicle's own acceptance limit — share your vehicle model, station, and SOC and it can be checked as an individual case.

Output

最大出力は、1口ご利用の場合で150kW、2口（2台同時充電）の場合で120kWです（/sources/ja/public-help/articles/23123162280473.md:20）。なお、一部ステーションでは最大出力を120kWに制限していますが、順次すべての拠点を150kWにアップデート予定です（/sources/ja/public-help/articles/40049220868505.md:22）。

プランやPowerX Firstによる出力制限はありません。PowerX Firstは充電速度に変更がなく、すべてのステーションが最大150kWの超急速充電の対象です（/sources/ja/public-help/articles/40049220868505.md:20）。Firstの特典は充電単価の割引や予約まわり（3日前からの予約、より長い予約枠など）であり、出力そのものは会員種別で変わりません（/sources/ja/runbooks/charging-use.md:27、/sources/ja/runbooks/charging-use.md:46）。

実際に出る出力が最大値に届かないことには、次のような要因があります。

- 外気温や充電器本体の温度により、充電器が自動的に出力を制限する場合がある
- 車両側が受け入れ可能な電力に左右されるため、車種や環境要因で最大出力に達しないことがある（/sources/ja/public-help/articles/23123162280473.md:21、/sources/ja/public-help/articles/23459356662809.md:20）
- 充電器側の出力制限や、バッテリー容量・受電スピード・バッテリー温度による差がある（/sources/ja/public-help/articles/23459018016793.md:20）
- SOC（充電率）が上がると出力が低下するのは正常な挙動です（/sources/ja/runbooks/charging-troubleshooting.md:460）

課金は充電した電力量（kWh）ベースで、時間課金ではないため、出力が低いことで料金的に不利になることはありません（/sources/ja/runbooks/charging-troubleshooting.md:460）。アプリ上に診断コードが表示されている場合は、そのコードとお車種を添えてカスタマーサポートへお問い合わせください（/sources/ja/public-help/articles/23459247986585.md:20）。
