Editor's Notes & Price Research
According to Amazon's product description, this is the newest model with a newly added Current Limiter.
Promo Code: EMCAKAS22
Note that this is the *new* model that includes current limiting, which means if a USB port is overloaded there's no fuse to permanately shut it down. This is the first time that this particular model has been discounted below $20.
With Newegg you will get the runaround. Newegg will point to Anker and Anker will point to Newegg. Look at the previous reviews at Newegg for Anker chargers. Anker says they will only warranty if purchased from Amazon or directly from Anker. I don't know if it's changed though.
Quote from Anker support email :Please be advised that both are for our 40w wall chargers, the first one is the fuse version while the second one is the upgraded current limited version.
