Thanks for the replies but unfortunately you are all wrong. I brought this multi pack in December 2010 as part of the xmas yo yo, secondly I tried a new experiment I used a regular atomiser on a regular battery with the booster attatched and guess what it works. Now my problem is the boosters either not been checked on all combinations, in which case this is poor product testing, secondly here is the quote from the booster advertising on UK TW SITE "Totally Wicked only recommends using this device with Tornado/Tank regular or mega batteries" My batteries are genuine TW batteries, I wouldn't know where to get them from anywhere else.
All I am saying here is that if the booster only works with certain combinations, a little note on the advertising would help allowing the customer to decide wether to purchase or not on that basis. Initially as I said I thought the booster had broken and only by trying different combos did I get it to work, luckily I have so many different pieces of equipment.
