Here's another nice option for the USB charger - little USB adapter that works with the SAE Battery Tender pigtail connector - so plug this into the Battery Tender SAE and charge the Chatterbox off it
Relatively inexpensive too - only $11 vs $50 for the Powerlet-USB adapter
Had some Zilla cash to spend and have the Battery Tender USB adapter on its way. Just hope no one walks off with my UClear while it is charging and I am eating lunch
