Query: Nice charger, but there are alternatives

I like my Kindle AC charger - it's elegant and compact. Unfortunately at the time I needed a spare charger, it was on indeterminate multi-week backorder.At that time, I went with theiGo Universal Wall (AC) and Auto (DC) Chargerwith iGo'sKindle Power Tip. That is working well.The (cheaper)iGo Universal Wall (AC) Chargerwill also work with the same Kindle Power Tip.Both of these are larger and less elegant than Amazon's Kindle charger. Now that the Amazon charger is available for immediate ship, these alternatives probably make less sense for normal use. However if you have multiple devices and only want to carry a single charger, the iGo chargers could still be useful.
