Understanding Key Projector Specs: Brightness, Resolution, and Technology Although a few have internal batteries, the majority of standard projectors-as well as most thin and light ones-are limited to use with AC power. Many come with soft carrying cases, but they could just as easily be slipped into a travel bag or backpack. The LG Minibeam LED projector is lightweight, but it doesn't sacrifice image quality.įinally, some standard projectors are still small and light enough to be easily portable, whether you're moving them between classrooms or taking them on a cross-country flight. They are highly portable, but you pay a premium for their svelteness, and they usually have a limited set of connection choices.
The next step up from these, thin-and-light projectors, are as wide, deep, and bright as standard models but barely an inch thick, and they weigh in at about 4 pounds. They pack a relatively high resolution, and their larger frames let them include more physical ports than their smaller brethren. Many manufacturers have introduced mini projectors that are generally a bit larger than palmtops, but considerably brighter. Many models come with built-in rechargeable batteries so you can use them away from a power outlet. A growing number offer USB-C connectivity. Many can project content from a smartphone or tablet, either wirelessly or via an HDMI port that supports Mobile High-Definition Link (MHL).
(If you do want to bring a laptop with you, though, check out our roundup of the best ultraportable laptops.) Some even have up to 8GB of internal memory for storing media files. Most pico and palmtop projectors can run files from a USB thumb drive and/or SD card, so you don't need to lug your laptop with them. The AAXA P7 Mini really does fit in your palm. Most are brighter than pico models, and have more connection options. Still, they are lightweight enough that you wouldn't think twice about packing one in a bag or a backpack. So-called palmtop projectors are larger (and generally brighter) than pico projectors, typically a bit too large to fit comfortably in the palm of your hand, even with your fingers outstretched.
