Takes Worx 20V batteries with the WA3551-style housing.
One pack per adapter, WORX's own or CEENR. The 300W runs on 18V/20V packs (DC 15–21V input) and uses one pack at a time, switching to the next automatically.

In short
The CEENR 300W 4-Slot Inverter Adapter for Worx 20V WA3551-Style Batteries lets one slot of the CEENR 300W 4-Slot Power Inverter run on a Worx 20V WA3551-style battery — WORX's own packs or CEENR packs.
It costs $15.99 and fits only that inverter. The inverter ships with four brand adapters you choose when you order; buy this one to add another brand, switch a slot to WORX, or keep a spare.
To install it, slide the adapter onto a slot's battery interface until it clicks, then slide your battery in until it locks; to remove it, press the battery release button and slide the pack out, then press the adapter release button and pull the adapter out.
The inverter takes 18V/20V packs (DC 15–21V input) in up to four slots and runs them one after another, switching automatically when a pack runs flat. Match the model printed on your pack before ordering: WORX's North American and European PowerShare packs use different housings that don't interchange.
For North American WA3520-style PowerShare packs (WA3520, WA3525, WA3575, WA3578), choose the WA3520-style adapter. It is not a tool adapter, and it does not fit PDnation batteries or the CEENR 150W inverters. Inverter and batteries sold separately. 3-year warranty, 30-day returns.

Common questions.
Which batteries does the Worx 20V (WA3551-style) adapter take?
Worx 20V batteries with the WA3551-style housing — WORX's own packs and CEENR packs both work. The CEENR 300W 4-Slot Inverter takes 18V/20V packs (DC 15–21V input). Match the model printed on your pack before ordering: WORX's North American and European PowerShare packs use different housings that don't interchange. For North American WA3520-style PowerShare packs (WA3520, WA3525, WA3575, WA3578), choose the WA3520-style adapter.
Does it fit a PDnation battery or the CEENR 150W inverter?
No. It fits only the four battery slots of the CEENR 300W 4-Slot Power Inverter. PDnation batteries connect to tools through a PDnation Brand Mount, which is a different part, and the CEENR 150W inverters clip straight onto a single brand's battery with no adapter. It is not a tool adapter either.
Does the 300W inverter already come with adapters?
Yes. Every CEENR 300W 4-Slot Inverter includes 4 brand adapters you choose when you order — any mix, and the same brand more than once. Buy this adapter on its own to add another brand, fill more slots with the same packs, or keep a spare.
How do I install and remove it?
Align the adapter with the battery interface on any of the inverter's four slots and slide it in until it clicks into place, then slide your battery into the adapter until it locks securely. To take it out, press the battery release button and slide the pack out, then press the adapter release button and pull the adapter out. Disconnect the batteries when the inverter is not in use or during transport.
Is this a genuine WORX product?
No. CEENR is an independent brand. This adapter is engineered by CEENR to connect WORX batteries to the CEENR 300W 4-Slot Inverter — it is not made by, sold by, or affiliated with WORX. WORX is a trademark of its owner, used here only to indicate compatibility.
What is the warranty and return policy?
A 3-year limited warranty from the date of purchase, plus a 30-day return window — email info@ceenr.com within 30 days of delivery for the return address; you ship it back and we refund your order plus the return shipping once it passes inspection.
