I love this little thing! I can't believe it's only $10 - most chargers cost more. I've only taken it on holiday once, but it was so easy to pack and seems to charge my watch at the same speed as my original Apple charger at home. It's easier to carry without a cord and has a handy loop to attach to a keychain etc if you like. To be clear this is not a portable battery it requires a male and female USB - reading some of the reviews this seems to be the reason for the negative.
