A Note on Fulfillment
For orders placed by 3:00 PM PST, we will do our best to ship them out of our Sunnyvale CA warehouse on the same day. If your shipping address is in Northern California, you will generally receive your order the next business day via UPS. (Even Amazon can't beat that!) Transit times (via UPS) for some other destinations: 2 business days to Southern California, Portland OR, Seattle WA, or Las Vegas NV. NOTE: USPS Parcel Select Ground may cost less than UPS, but it uses different handling and routing than your regular first-class mail and can take an unexpectedly long time to arrive. Therefore, for time-sensitive orders, please opt UPS.

I find it eliminates buzz, while still keeping everything charged." -- This is the handiest travel battery you can buy [Review]
