Anker 10000mAh External Battery Only $19, Panic Buttons for Hotel Housekeeping & More

Highlights and headlines from around the web, with a focus on deals:

Via Slickdeals, Anker is offering their PowerCore 10000mAH high speed, ultra compact power bank for only $19.10 with free prime shipping, the lowest price it’s been in over a year. Even better, it’s about the size of a credit card and weighs only ~6oz. I rely on external batteries to keep me going on long travel days, especially when flying planes without power outlets, and Anker is one of the most reliable.

Where are the world’s happiest airports? Highly skeptical of the results, I know I’m unlikely to ever use those survey machines, and even if I do, it would only be after an exceptionally bad or good experience. Nothing in between. What is interesting is the data onÂ when during the week andÂ where in the airport people are the happiest. Hint: not late at night at baggage reclaim.
