Thanks...I have actually been looking at 510 adapters. I just don't know the difference yet so I figured I would try some new item in a few weeks...next pay period. 

Thanks for responding. I was only looking at as a start because I can 2 for the price of 1. I couldn't afford to get us both one for double the price. I was thinking it would be easier to quit if we both tried at the same time.
Large capacity 3.7 volt, 800 mAh, sealed, passthrough, rechargeable manual battery with new ON/OFF feature and LED indicators.
Features:
Large capacity 3.7 volt, 800mAh
Sealed battery to prevent liquid corrosion
Passthrough feature so you can use your Leo while its charging
Manual button allows user to activate battery when using and blinks when battery needs charging - button light turns orange when battery is starting to run low
New ON/OFF feature prevents accidental activation while in purse or pocket
Fully charges in 1-3 hours - one charge will support a heavy user for at least 8-12 hours
Hidden mini usb port allows for charging on any computer - wall & car adaptors available
That's a pretty good deal but I think in the long run you will be happier with a 510 style battery. You could also get a 510 1100 mah kit here for 40 bucks- Ego 510 1100Mah Black Super Excalibur Kit [Super exc Blk 1100 kit] - $40.00 : Vapors Choice, Ecigarettes & Parts
Or you could get a standard 510 Kgo kit from here for 43.99- KGO kit1100mAh by SLB
I have personally dealt with Hoosiers and they have sold 1000's of those Kgo kits to a whole lot of satisfied vapors in this forum.
Both those kits would allow you to use 510 stuff and give you better longer lasting batteries. Then in the future you could simply purchase more batteries to allow both you and your husband to own 2 batteries each.
I thank you for sending me here...I can honestly say I've never seen this site in all my hours of searching. Be back in a few...
