"Does the Job"
For me, My Bluetooth only holds a charge of about close to three days. It helps to have another charger to use, when I'm in the car.

"For Explorer 330"
This is the official adapter (69520-01) for the Plantronics Explorer 330 (probably others, too).
-- I just had an online chat with Plantronics Support --
: I recently purchased an Explorer 330 headset, but would also like to get a car charger for it. I can't find information about such products on your web site, can you tell me what I'm looking for?
: The part number for the car charger is 69520-01. You can get those from our distributors.
: Great - I'll look for that product number. Thank you.
: No problem. have a good day.

"Works as expected"
Works exactly like it os supposed to. Plugs into the car lighter and charges my bluetooth.

"Life saver!"
I was thrilled to find this after misplacing my home charger. I cannot get behind the wheel without my headset. I travel way too much to be on the road trying to drive one-handed. This little gem will save me much heartache and cramped neck and arms to be able to charge my headset on the road.

"This should come with the headset."
I use my headset only in the car and it is nice to have a charger inside of the car to charge it.
