Yes. Mercedes-Benz Charging Hubs are part of the PowerX charging network, so you can find and use them through the PowerX app just like any other PowerX station.

A few helpful details:

- **Locations**: PowerX currently lists Mercedes-Benz Charging Hubs at Komazawa (Tokyo), Chiba Park, Kashiwa Shonan, Nagoya Sakae, and Fukuoka, following the PowerX–Mercedes-Benz partnership to build out high-power charging across Japan (/sources/en/reference/stations.md:88, 179, 238, 438, 842, 1058, 1093).
- **You don't need a Mercedes**: Even though the site name includes a brand, vehicles are not restricted. Any EV compatible with the CHAdeMO standard can charge there regardless of maker or model — Mercedes vehicles included (/sources/en/runbooks/compatibility.md:163-167).
- **One caveat**: Charging may not work properly if you're using a CHAdeMO adapter, so please refrain from charging with one (/sources/en/runbooks/compatibility.md:167).

If you let me know which location you're planning to visit, I can also check its operating hours and any parking notes (some hubs, like Chiba Park and Nagoya Sakae, have specific parking entrance or payment instructions).

ベンツ（メルセデス・ベンツ）のディーラーに設置されている充電器については、次の2つの場合に分けてご案内します。

**1. メルセデス・ベンツ独自の充電器の場合**
ディーラーに設置された機器がメルセデス・ベンツ独自のものである場合、PowerXの機器とは異なるため、PowerXアプリではご利用いただけません。同種のお問い合わせについても、この旨でご案内することとしています（/sources/ja/runbooks/stations.md:246-250）。

**2. PowerXが運営する「MERCEDES-BENZ CHARGING HUB」の場合**
一方、メルセデス・ベンツとの提携によりPowerXが設置・運営している「MERCEDES-BENZ CHARGING HUB」（駒沢／千葉公園／かしわ沼南／名古屋栄／福岡）は、PowerXの超急速EV充電ステーション一覧に含まれており、PowerXアプリからご利用いただけます（/sources/ja/reference/stations.md:88, 179, 238, 438, 842）。

ご利用を予定されている場所がどちらに該当するか不明な場合は、ステーション名や住所をお知らせいただければ、確認のうえご案内いたします。

なお補足として、PowerXの充電器は車種を問わずCHAdeMO規格対応のEVであればご利用可能です（メルセデスの車両も同様です）。ただしCHAdeMOアダプタを使用した場合、正常に充電されないケースがあるため、アダプタのご利用はお控えいただくようお願いしております（/sources/ja/runbooks/compatibility.md:163-167）。

Short answer: no — the chargers installed at Mercedes‑Benz dealerships are not PowerX equipment, so the PowerX app can't start a session on them.

Details from the support material:

- There's a documented case exactly matching your question ("Can the chargers at the Benz dealership be charged with the PX app?"), and the guidance is that the dealership's own charging equipment differs from PowerX's, so it isn't operated through the PowerX app (/sources/en/runbooks/stations.md:246, /sources/ja/runbooks/stations.md:246). Use the network/operator the dealer directs you to for those units.

Two things worth not mixing up:

1. PowerX sites that happen to sit at a dealer are open to everyone. Where PowerX has installed chargers at BMW/Audi/MINI dealer locations, vehicles are not restricted by brand — any EV that supports the CHAdeMO standard can charge, Mercedes vehicles included (/sources/en/runbooks/compatibility.md:167). You do need the PowerX app installed and a registered account to use them (/sources/en/runbooks/compatibility.md:181).
2. Brand‑named "Mercedes‑Benz Charging Hub" locations (e.g. Chiba Park, Nagoya Sakae) appear in PowerX's own Help Center as PowerX‑network charging facilities, alongside PowerX–Mercedes‑Benz partnership announcements (/sources/en/reference/stations.md:1058, /sources/en/reference/stations.md:1093). Those are PowerX‑operated hub sites, distinct from a dealer's own wall charger. I only confirmed the titles/parking articles for those hubs in this workspace, not a full per‑site usage policy.

One practical caveat either way: charging via a CHAdeMO adapter may not work properly, so it's asked not to be used (/sources/en/runbooks/compatibility.md:167).

If you tell me the specific site name shown in the app (or the dealership), I can check whether it's a PowerX‑operated station and what's needed to start charging there.

メルセデス・ベンツのディーラーが自社で設置された充電器は、PowerXアプリではご利用いただけません。ディーラー設置の機器はPowerXの充電器とは別の仕組みで運用されているため、アプリでの予約・起動・課金対象外となります（/sources/ja/runbooks/stations.md:246-250）。PowerXアプリで充電できるのはPowerXが提供する充電器のみで、他社製・施設独自の充電器は別途登録が必要になるか、そもそも利用対象外です（/sources/ja/runbooks/stations.md:340）。

一方で、名称にベンツが入っていても、PowerXとメルセデス・ベンツが提携して開設した「MERCEDES-BENZ CHARGING HUB」はPowerXのステーションですので、アプリで予約・充電をご利用いただけます。対象は以下の拠点です（/sources/ja/reference/stations.md:88, 179, 238, 438, 842）。

- MERCEDES-BENZ CHARGING HUB 駒沢（東京都世田谷区／24時間・年中無休）
- MERCEDES-BENZ CHARGING HUB 千葉公園
- MERCEDES-BENZ CHARGING HUB かしわ沼南
- MERCEDES-BENZ CHARGING HUB 名古屋栄
- MERCEDES-BENZ CHARGING HUB 福岡

見分け方としては、PowerXアプリのマップ上に該当ステーションとして表示されるかをご確認ください。表示されている拠点であればそのまま予約・充電が可能で、表示されないディーラー設置の充電器はご利用いただけません。なお、名古屋栄では充電利用者向けの駐車場精算方法が別途案内されており、千葉公園は入口駐車場や充電口位置に応じた推奨駐車位置がございますので、ご利用前に各拠点の注意事項をご確認ください。
