In the Not-So-Long-Ago Days...
I used to lug around all kinds of equipment for my investigations, such as digital and video cameras, cell phone, notebooks, pens, digital recorders, flashlight, magnifying glass, measuring tape and more. However, my smartphone now contains a lot of these tools as apps. Yes, even the measuring tape! I also have apps to do language translations, capture video if motion is detected, capture public data about homes, and much more.
Keeping Devices Charged
Back when I lugged around a bag or two of equipment, I had to always ensure some devices had been charged sufficiently so they'd have enough "juice" when I was out in the field. Just my luck if I hadn't taken the time to charge my cell phone or the video camera or any other item!
When a digital camera, for example, ran out of power, I'd have to wing it. If I had a video camera with me, I'd use its photo feature to take still shots. But I avoided using the camera on my cell phone because the quality was so shoddy, and I didn't want to insert amateurish, cheap-looking photos into an investigative report. Good news is that today's smartphones take clear, usable photos and video.
These days I need to always keep the smartphone charged. Fortunately, we have battery chargers in both of our vehicles to help with this.
