ApoloSign makes three portable touchscreen Android TVs, and picking between them mostly comes down to three things: how big a screen the room can fit, how long the battery needs to last between charges, and whether the TV needs to travel. This guide compares the specs ApoloSign lists for each model side by side, rather than picking a single "best" — the right size depends on the dorm.

Every figure below (screen size, resolution, battery capacity and rated hours, brightness, price) is taken directly from each product's own listed specifications — nothing here is estimated.
24 inches, 1080p only, $619. Runs on a 6800mAh battery rated for about 4 hours at 50% brightness — the shortest of the three — and tops out at 250 nits of brightness, the dimmest of the lineup. It's the only one of the three with AirPlay and Miracast casting support in addition to standard Wi-Fi/Bluetooth/HDMI.
32 inches, with a choice of 1080p or 4K panel, $719. Its 15000mAh battery is rated for the longest runtime of the three (~6 hours at 50% brightness), and it's the only size offered with a 4K panel and up to 256GB of storage. Brightness is rated at 300 nits.
27 inches, 1080p only, $999 — the most expensive of the three, and the only one built into a rugged briefcase with a handle and latch instead of a wheeled stand. It's also the brightest at 450 nits and the only one with a built-in 40W speaker system and 45W USB-C fast charging capable of powering other devices.
Screen size and price scale together here in an unusual way: the PackGo is the smallest of the three screens (27 inches) but the most expensive, because the price is paying for the briefcase build and stronger audio/charging, not a bigger panel. For a stationary dorm setup, the 32-inch offers the most screen and the longest battery life for the money; the 24-inch is the pick if budget matters more than screen size or battery runtime; the PackGo only makes sense if the TV genuinely needs to survive being packed and moved.
The 32-inch is rated for the longest runtime at up to ~6 hours at 50% brightness, matching the PackGo's ~6-hour rating; the 24-inch is rated lowest at ~4 hours, per each product's listed battery specifications.
The 4K variant of the 32-inch adds a higher-resolution panel and steps up to 256GB storage (versus 128GB on the 1080p variant) for the same 16GB of RAM — whether it's worth the difference depends on whether the room will be used for close-up detail work like gaming or reading, versus general streaming where 1080p is usually sufficient.
The PackGo is the only one of the three explicitly built and marketed for outdoor/travel use, with the brightest panel (450 nits) and a rugged briefcase enclosure; the 24-inch and 32-inch are designed around an indoor wheeled stand.
