Short answer: PowerX currently asks Tesla owners **not** to charge at PowerX stations.

Details from the official Help Center notice (last updated July 15, 2026):

- PowerX chargers use a CHAdeMO connector, so Tesla vehicles can only connect via a Tesla CHAdeMO adapter. PowerX has reported multiple Tesla vehicle failures (in the onboard transformer/DC converter) while using PowerX chargers, and suspects an issue related to the adapter's CHAdeMO-to-NACS signal conversion (/sources/ja/public-help/articles/25769060509081.md:26-28).
- Until this issue is resolved, PowerX officially requests that customers **refrain from using its chargers with Tesla vehicles** (/sources/ja/public-help/articles/25769060509081.md:30).
- The station terms of service were also revised: all EVs charging via a CHAdeMO adapter — including Teslas — are outside the scope of PowerX's liability, and charging such vehicles is done at the customer's own discretion (/sources/ja/public-help/articles/25769060509081.md:36).

So while a Tesla may physically connect through an adapter, charging is not recommended, may not work properly, and any resulting vehicle damage would not be covered by PowerX. For the latest status, I'd recommend checking PowerX's official announcements (X/note) or the Help Center article before visiting a station.

テスラ車でのご利用については、現在ご遠慮いただくよう案内している状況です。

公式ヘルプセンターのお知らせ（2026年7月15日更新）によると、PowerXの充電器を利用中に複数のテスラ車両で故障が発生しており、CHAdeMOアダプターを使用した場合に正常に充電されないケースがあるため、**問題が解決されるまでテスラ車での弊社充電器のご利用をお控えいただくようお願いしています**（/sources/ja/public-help/articles/25769060509081.md:30）。

あわせて以下の点にもご注意ください。

- 2024年1月31日にサービス利用規約が改定され、テスラ車両を含むCHAdeMOアダプターを使用するすべてのEVは弊社の責任対象外となり、当該車両の充電はお客様ご自身の裁量に委ねられています（/sources/ja/public-help/articles/25769060509081.md:36）。
- テスラ車はNACS充電規格を採用しており、PowerXの充電器（CHAdeMO）をご利用になる場合はCHAdeMOアダプターが必要ですが、このアダプター経由での信号変換に関わる不具合の可能性について、テスラモーターズジャパン社と共同で検証が続けられています（/sources/ja/public-help/articles/25769060509081.md:26-28）。

つまり、物理的に充電ケーブルを接続することはできたとしても、車両故障のリスクと補償対象外となるリスクがあるため、現時点ではテスラ車でのご利用をお控えいただくのが安全です。最新状況はPowerXの公式X（旧Twitter）アカウントやnote、ヘルプセンターのお知らせで発信されていますので、ご利用前に必ずご確認いただくようお願いいたします。

Short answer: PowerX asks Tesla drivers **not** to charge at its stations.

Details from the current official guidance:

- The Help Center notice "Please refrain from using CHAdeMO adapters" (last updated 2026-07-15) states that when a CHAdeMO adapter is used, charging may not work properly, and customers are asked to refrain from using one — /sources/ja/public-help/articles/25769060509081.md:19
- The standing notice dated 2024-02-22 says that several Tesla vehicles were damaged (transformer failures) while using PowerX chargers. Teslas use the NACS standard and take AC and DC through the same inlet, so PowerX cannot investigate on its own whether the Tesla CHAdeMO→NACS adapter is the cause, and it asks Tesla owners to refrain from using PowerX chargers until the matter is resolved with Tesla Motors Japan — /sources/ja/public-help/articles/25769060509081.md:26-30
- The service terms were revised (2024-01-31) so that any EV using a CHAdeMO adapter, including Teslas, falls outside PowerX's liability; charging is done at the customer's own discretion. Article 7(5) of the terms similarly makes use of any equipment other than the installed charger (e.g., adapters) entirely the user's own responsibility — /sources/ja/public-help/articles/25769060509081.md:36 and /sources/ja/public-help/articles/28163480600729.md:30
- The support runbook answer for "Can Tesla vehicles charge here?" (CS-053) is: charging may not work properly with a CHAdeMO adapter, so please refrain from charging if you are using one — /sources/en/runbooks/charging-use.md:160-163

Practical takeaway: since a Tesla in Japan needs a CHAdeMO adapter to plug into a PowerX dispenser, you should plan on using another network. Also note that if you're looking at a free-charging campaign, sessions via a CHAdeMO adapter (Teslas, etc.) are specifically flagged for separate conditions — /sources/ja/public-help/articles/27925450585369.md:45

One caveat: this restriction is about adapter-based charging, and the workspace does not list any PowerX station offering a native connector that fits a Tesla without an adapter, so I can't confirm any location where a Tesla could charge.

テスラ車については、PowerXの充電器のご利用はお控えいただくようお願いしております。

理由と根拠は以下のとおりです。

- 公式アナウンス（最終更新 2026-07-15）で「CHAdeMOアダプターを使用した場合、正常に充電されないケースがあります。ご利用はお控えいただくようお願い申し上げます」と案内されています（/sources/ja/public-help/articles/25769060509081.md:20）。
- テスラ車はNACS規格を採用しており、PowerXのCHAdeMO充電器を利用する場合はCHAdeMO→NACSの変換アダプターを介す形になります。2023年11月以降、充電器利用後に車両側（変圧器）の故障報告が複数寄せられており、原因調査が完了するまでテスラ車での利用を控えるようご案内している状況です（/sources/ja/public-help/articles/25769060509081.md:26-30、/sources/ja/public-help/articles/25769060509081.md:54）。
- また、2024年1月31日付で利用規約が改定され、アダプターなどPowerXが設置していない機器を用いて充電した場合に生じた一切の結果はユーザーの自己責任となり、PowerXでは責任を負わないこととされています（サービス利用規約 第7条5項／/sources/ja/public-help/articles/28163480600729.md:30）。キャンペーンの無料対象外となる場合もあります（/sources/ja/public-help/articles/27925450585369.md:45）。

したがいまして、アダプターで物理的に接続できる場合でも、充電は行わないでください。本件の最新情報はPowerX公式のX（旧Twitter）・noteアカウントで発信されています。なお、すでにアダプター利用後に車両側へ不具合が疑われる症状が出ている場合は、その旨を添えてお問い合わせください。
