I wrote earlier this month on Recharge4 versus the Proporta Charger. Well it seems you can have convenience or speed but not both. Further testing has shown what I suspected earlier that the Proporta is slooooooooooow to charge through the USB socket. Also it doesn’t seem to charge as many times as the Recharge4. That said I would still rather have that than to have to carry a bulky wall charger.
