I survived another CES without having my laptop or phone come close to running out of power during the workday, which is worth a little celebration but may also indicate that I did CES wrong.

One reason for this efficient electrical usage is that I showed up in Vegas for a new laptop for the first time since 2013. The HP Spectre x360 laptop that replaced my MacBook Air couldn’t get through an entire day without a recharge, but plugging it in during lunch and any subsequent writing time freed me from having to think about its battery for the rest of the day.

The Google Pixel phone I bought last summer was thirstier, mainly because I could never really put that down even after dark. But I still never needed to top off the phone with the external charger I bought.

Having both the phone and laptop charge via USB-C delivered an added bonus: Whenever I was sitting near an electrical outlet, I could plug either device into the laptop’s charger.

CES telecom, however, got no such upgrade. The press-room WiFi worked at the Mandalay Bay conference center but often did not in the media center I used at the Las Vegas Convention Center. And having to enter a new password every day–what looked like a misguided episode of IT security theater–did not enhance the experience.

Fortunately, the cheap USB-to-Ethernet adapter that my MacBook had inexplicably stopped recognizing a few years back worked without fuss on the HP so I often reverted to using wired connections. The irony of me offering an “it just works!” testimony to a Windows PC is duly noted.

T-Mobile’s LTE, meanwhile, crumpled inside the Sands and often struggled to serve up bandwidth at the LVCC. More than once, this meant I had to trust my luck in CES traffic when Google Maps coudn’t produce any road-congestion data.

I packed two devices I’ve carried for years to CES but only used one. The Belkin travel power strip I’ve brought since 2012 avoided some unpleasantness in a packed press room Monday but wasn’t necessary after then. The Canon point-and-shoot camera I’ve had since 2014, however, never left my bag. The camera in my Pixel is that good for close-up shots, and I didn’t come across any subjects that would have required the Canon’s superior zoom lens.

I also didn’t come across a worthy, pocket-sized successor to that “real” camera at any CES booths. But with some 2.75 million square feet of exhibits at this year’s show, I could have easily missed that and many other solutions to my travel-tech issues.
