AAXA P2-B Smart Pico Projector
The AAXA P2-B Smart Pico Projector comes equipped with a mini tripod for quick setup, while the remote control allows users to conveniently switch among its many inputs, including mini-HDMI, microSD, and USB, from a distance to display movies, photos, and text files. It also streams content from preinstalled apps including YouTube, Hulu, and Netflix. Wi-Fi and Bluetooth connectivity are featured, while the optional mobile high-definition link (MHL) cables can connect a smartphone or tablet PC, enabling exhibitors to easily display content from those devices as well. If an electrical outlet isn't readily available, the rechargeable lithium-ion battery can power the projector for up to 2.5 hours when the unit is running in its energy-frugal eco mode.

Pros:
➤ The included mini tripod offers flexibility and fast, easy setup.
➤ Weighing just .55 pounds, it is the lightest of the units reviewed here.
➤ Projected images can be as small as 8 inches, a plus if your screen area is particularly small.
➤ The LED lamp lasts up to 20,000 hours, decreasing the likelihood of a show-floor burnout.

Cons:
➤ The native resolution of 854-by-480 pixels and maximum brightness of 130 ANSI lumens are low compared to many other models.
➤ The unit lacks keystone correction, meaning images may be skewed if the projector isn't in an optimal position.
➤ This projector lacks any internal storage.


Laser Beam Pro C200
An Innovation Award winner at the 2017 International Consumer Electronics Show, the Laser Beam Pro from Cremotech Co. Ltd. uses a Class 1 Eye-Safe Laser to display images. That means exhibitors don't need to fuss with trying to focus any imagery projected within the unit's 12- to 150-inch range. The nine navigation buttons on the top of the projector lend an intuitive, tactile feedback for all its functions, and the 8GB of internal storage enables users to display saved content without having to rely on inconsistent Wi-Fi that can result in slow and choppy videos. Built-in Bluetooth functionality allows users to connect up to seven different Bluetooth-enabled devices such as a mouse, headset, and external speakers.

Pros:
➤ The unit's autofocusing capability means exhibitors don't have to manually tinker with the lens to adjust blurry images on the fly.
➤ Its 8GB worth of internal storage is the largest of the units reviewed here.
➤ Weighing just .57 pounds, the unit is exceptionally easy to transport.

Cons:
➤ The battery life of just two hours is shorter than many options on the market, meaning exhibitors may need to consider in-booth power to keep this unit running throughout show hours.
➤ Its lamp life of 10,000 hours is significantly less than most LEDs.


Optoma ML750ST
Offering a native resolution of 1,280-by-800 pixels, a contrast ratio of 20,000:1, and a brightness rating of 700 ANSI lumens, the Optoma ML750ST produces a vivid picture with high color accuracy. More conveniently, its short throw ratio of 0.8:1 (many projectors have a 1.2:1 to 1.5:1 ratio) means the unit only has to be 4 feet away from the screen (instead of the more common 6 to 7.5 feet)in order to display an image 5 feet wide – a major plus in a tight space, such as a small trade show booth. The multiple connectivity options include an HDMI port, a microSD slot, and a USB port, which works with the unit's integrated document reader to project PDFs, Word documents, and more from a portable drive. The optional plug-in dongle and app, called HDCast Pro, permit the projector to wirelessly access compatible DLNA-, Miracast-, and Airplay-compatible smartphones, tablets, and other devices. The unit is whisper quiet, with an audible noise level generated by the fan running about 22 decibels, nearly 25 percent less than other projectors. Additionally, the unit comes with a carrying case, AC power cord, universal input/output cable, remote control, and quick-start card.

Pros:
➤ This unit's throw ratio of 0.8:1 makes it optimal for small spaces, such as 10-by-10 booths.
➤ An optional plug-in and app allow wireless access to many DLNA-, Miracast-, and Airplay-compatible devices.
➤ At 22 decibels, the audible noise level produced by the fan and other internal components makes it one of the quietest portable projectors on the market.

Cons:
➤ Measuring 4.4-by-1.6-by-4.1 inches, this projector is larger than some of the smaller, lighter, and more easily portable models reviewed here.
➤ While this unit does offer Wi-Fi connectivity to stream content from the internet, doing so requires purchasing an optional adapter.
➤ This unit has no built-in battery, so an external power source is a must.


Nebula Capsule Smart Mini Projector
What your audience hears is as important as what it sees. The Nebula Capsule Smart Mini Projector addresses this sometimes-overlooked truth with an omnidirectional speaker set in an aluminum body that resembles an Amazon Echo. Powered by a 100-ANSI-lumen projector, this unit keeps its picture vibrant all the way up to its 100-inch maximum size while displaying content from documents to documentaries directly from smartphones and other devices via the Capsule Control app available on Google Play and the App Store. That wireless capability also means content can be streamed directly from websites such as Vimeo and YouTube. Focus is manually adjusted through a wheel mounted on the unit's side, and an included remote control connects to a receiver built into the back of the device via infrared.

Pros:
➤ A 360-degree speaker produces better sound than most comparable projector units.
➤ The Capsule Control app allows this unit to stream content from Wi-Fi-enabled devices.
➤ The lamp life of up to 30,000 hours is higher than most other models with similar features.

Cons:
➤ A lower native resolution and a maximum brightness of 100 ANSI lumens mean this unit's images may not be as vibrant as other projectors'.
➤ The focus-adjustment wheel mounted on the side is small and may be difficult for some to use with any precision.


PowerLite 1795F Wireless Full HD 1080p 3LCD Projector
An outlier in this group, the Epson PowerLite 1795F is larger and costlier than any of the other units reviewed here, but it packs an accordingly weighty visual punch. The native resolution of 1,920-by-1,080 pixels and 3,200 ANSI lumens of brightness – plus a Philips Lighting LCD lamp – translate to exceptionally crisp images when displaying any high-definition content. The projector is Miracast-enabled, a recent connectivity standard that allows it to wirelessly display HD video from a smartphone or other device. It also supports Chromecast-, Roku-, and MHL-enabled devices. In addition, this unit comes with a soft-sided carrying case and a laser pointer included.

Pros:
➤ The LCD lamp produces remarkably bright whites and vibrant colors, resulting in exceptional image clarity.
➤ The native resolution of 1,920-by-1,080 pixels is the highest among the units listed here.
➤ This unit offers both vertical and horizontal keystone correction, meaning images won't appear skewed if the projector isn't in an ideal location in the exhibit.

Cons:
➤ While still portable, the PowerLite 1795F is larger and heavier than other models, which could be a key consideration if portability is of prime concern.
➤ Priced at $1,000, this projector is the most expensive of the six options reviewed here.
➤ The lack of internal storage means content must be saved on an external device in order to be accessed.


Minibeam LED Projector
Connections abound with the LG Minibeam LED Projector, including a single HDMI port that supports MHL, allowing exhibitors to easily stream video from any MHL-enabled device. There's also a USB Type A port that facilitates access to content stored on thumb drives, such as photos, videos, and music files, while the VGA port can connect the projector to a laptop computer. Further setting the unit apart is a coaxial connector for the projector's built-in TV tuner, which lets users connect to a cable box and project live TV programming directly onto a screen. Similar to the Optoma ML750ST, the unit's fan produces an audible noise level that can run as low as roughly 23 decibels, which can be a benefit when presenting in a noisy exhibit hall. If audio is an important component of your in-booth presentations, you'll need to connect headphones or an external speaker via the audio-out jack.

Pros:
➤ This unit has the highest contrast ratio among the projectors reviewed here, enabling it to compensate for ambient light.
➤ A 30,000-hour lamp life means exhibitors can expect nearly 3.4 years of continuous operation before changing the bulb.
➤ The coaxial connector can connect to a cable box and display live TV.
➤ Low noise levels make it among the quietest in this round-up.

Cons:
➤ This projector's lack of wireless connectivity may be a dealbreaker if you need to stream content directly from the internet.
➤ The native resolution of 1,280-by-720 pixels is among the lowest listed here, which may result in a muddier picture.
