Lifehacker had an article on how to Replace Your Lost Cellphone Charger for Free.
Next time you lose your phone charger, don’t buy another one. Go to a hotel and say you think you lost it there. It’s the #1 most left behind item at hotels, so most places have a big bin filled with every phone charger imaginable.
An excellent tip for those travelers, and those who don’t want to bring their charger. Just make sure to return it to the hotel if you no longer need it, citing the excuse that you found your own elsewhere (karma).
