Safety feature
Built-in BMS Protection
Integrated Battery Management System (BMS) helps prevent battery over-discharge and improves safety.
Use your Bosch 18V GBA (Blue) batteries on Dyson V8 cordless tools, without buying into a second battery platform. The molded ABS housing keeps it light and hard-wearing, and pure copper contacts keep current delivery steady. Your existing batteries do more work, and there is no second ecosystem to buy into. It also carries battery protection electronics (BMS) inside.

Why choose this adapter
- A Battery Management System inside the adapter cuts power before the battery is drained too far — protection your battery may not have on its own.
- Injection-moulded ABS, not 3D printed — no layer lines to split under load.
- Solid copper terminals, so less of the current is lost as heat.
- Rated for 55A continuous with 100A peak at 18VDC for up to 2 seconds, so a high-draw tool is not held back by the adapter.
- Covered by a 12-month warranty from the day it arrives.
Bosch 18V GBA (Blue) and Dyson V8 compatibility
It works in one direction only: Bosch batteries powering Dyson tools. For the opposite pairing, see adapters that run on Dyson V8 batteries.
Compatibility can vary with the exact battery and tool model. Before ordering, confirm that your battery belongs to the Bosch 18V GBA (Blue) platform and that your tool takes Dyson V8 batteries.
Important charging and safety information
This adapter is for powering cordless tools and nothing else. It cannot charge Bosch or Dyson batteries and must never be connected to a charger of any kind. Always take the battery out of the adapter before charging, and charge it on the original charger made for your Bosch 18V GBA (Blue) battery.

No tools, no wiring, no modifications.
Bosch 18V GBA (Blue) to Dyson V8 — Common Questions
Will this fit my other Bosch batteries?
Only Bosch 18V GBA (Blue) batteries. Bosch also sells Bosch 12V, Bosch 18V PBA (Green), and those use a different socket — same brand, different rail and contacts, so they need their own adapter. Compare the rail on your battery with the photos before ordering.
Will my Dyson V8 tool run as long on a Bosch 18V GBA (Blue) battery?
Runtime comes from the battery, not the adapter: a 5.0Ah Bosch 18V GBA (Blue) battery lasts roughly twice as long as a 2.5Ah one. For this pairing use 3.0 Ah or more — a smaller battery can sag under what a Dyson V8 tool draws and cut out before it is empty.
Could this damage my Bosch 18V GBA (Blue) battery or my Dyson V8 tool?
Used with undamaged, compatible equipment it is not expected to. This adapter has its own Battery Management System, which cuts power before the battery is drained too far, so it protects the battery even where the battery has no protection of its own. Stop using it if the adapter becomes unusually hot, the contacts look damaged, or the tool behaves oddly.
Can I charge through the adapter?
No, and it should never be attempted. The adapter carries power one way only, out to the Dyson V8 tool — there is no charging circuit inside it. Connecting it to a charger puts the battery, the charger and the adapter at risk. Always take the Bosch 18V GBA (Blue) battery off the adapter and charge it on its own charger.
Does it work with third-party Bosch batteries?
Usually. What matters is the socket, not the badge: if the battery slides on and locks the way an original does, the adapter takes it and the Dyson V8 tool runs. Aftermarket moulding does vary, so if yours looks unusual send us a photo and we will check before you order.
How much does it add to the Dyson V8 tool?
156 g (5.5 oz) and a short extension between battery and tool. You notice it overhead or in a tight cabinet; on a drill or driver held normally it disappears.
