Many of the tablets do special negotiation on power, and the chargers and others expect that. I'd recommend having a USB condom in general, but in this case it'd probably also solve the negotiation problem. These are the ones I use. (
Also there are many extended charge batteries provided by Anker which may work for your needs. I was looking at buying this one for my Dad who has a CPAP machine and would like to be able to camp. I imagine a smaller one would work depending on what you want. (
