Counting my coins...

for a battery operated heating pad for my trip!

I'm looking at this one:  Tempachair Cushion  - Pros for this one is that it is portable, rechargeable (up to 300 charges) and has good heat.  It looks like I can position it easily enough for my hip as well.  This one charges in two hours.  That would be nice if we have a layover.  Cons:  Low heat it only lasts for up to four hours (120 degrees), high heat it lasts for 2 hours (140 degrees).

This one:  Deluxe Heated Seat  - Pros for this one longer lasting heat - 6 hours - at the heat saver setting - BUT  but I don't know what temp that is.  Rechargeable.  Cons:  Not sure it'll work well on my hip - it's more designed to be sat on or for your back.

This one:  The Bench Warmer - holds heat longer - 5-7 hours at 115 degrees.  Wish I knew what my plug in heating pad temp was at!  This one says it never needs the batteries replaced - which would be nice - but that kind of a promise scares me.  Again it doesn't look like I can position it for my hip very easily.  It charges over night.

Either way I'm counting and rolling my coins tonight.  This jar of coins was supposed to be for a birthday massage for me, but I really need to get a heating pad for my trip.

Do you see any others out there that would work?  I need good heat, easily positionable, rechargeable and portable.  I would like to order something in the next few days...so if you see anything out there - let me know ASAP!
