Thank all of you for your comments. I did think about a ziplock bag but it would be slippery.
I did not get any comments comparing the AquaPac and the Gomadic.
I was hopping for something that cost less the $100 for the OtterBox 1900 but I do like the idea of being able to charge my x51v while it is in the case and protection if I drop it on a rocky beach.
I use a 1800 mAh Mugen battery. Looking at the specs for the 1900 max thickness is 23.5mm, The Dell site says the x51v is 16.9mm high, the Mugen says it adds 2.3mm which would put the total to 19.2mm.
Do any of you use your OtterBox 1900 with a 51 or I gess 50 Axium and a 1800 Mugen battery?
