Portronics Beem 470 Mini VS Portronics Beem 520

Neither the Portronics Beem 470 Mini nor the Portronics Beem 520 uses a laser light source, so both rely on conventional lamp or LED projection technology — no advantage to either on that front. Where they diverge meaningfully is in physical form factor. The Beem 470 Mini is notably more cube-like at 136 × 136 × 213 mm, while the Beem 520 spreads out into a flatter, wider profile at 260 × 140 × 120 mm. In practice, the 470 Mini's taller, more compact footprint may suit shelf placement or tight spaces, whereas the 520's low-profile shape sits more naturally on a desk or table without protruding vertically.

The weight difference is the most impactful differentiator here: the Beem 520 is significantly lighter at 950 g versus the 470 Mini's 1350 g — a gap of 400 g, or roughly 30% heavier for the Mini. For a portable projector, that extra weight is noticeable during transport and handling, giving the Beem 520 a real edge in portability. Interestingly, despite being lighter, the Beem 520 has a slightly larger calculated volume (4368 cm³ vs. 3939 cm³), meaning it occupies more space in a bag even though it weighs less — a trade-off worth considering when packing.

Overall, the Beem 520 holds a clear advantage in this group purely on weight, making it the more carry-friendly option. However, if vertical compactness matters more than weight — for instance, fitting into a specific shelf or compartment — the 470 Mini's smaller footprint in two dimensions could be preferable. Users prioritizing day-to-day portability should lean toward the Beem 520.

Resolution is where these two projectors take very different stances. The Beem 520 outputs at 1080p, delivering a full HD image with noticeably sharper text, finer detail, and more defined edges — especially apparent on larger screens or when sitting closer to the projection. The Beem 470 Mini tops out at 720p, which is adequate for casual viewing but will show softer imagery by comparison, particularly with HD content sources.

Flip the script on screen size, though, and the 470 Mini fights back hard. It can throw an image up to 150″ and needs as little as 1.5 m of distance to do so, making it genuinely flexible in smaller rooms. The Beem 520 caps at 88″ and requires at least 2 m of throw distance — a meaningful constraint in compact living spaces. So while the 520 wins on pixel count, the 470 Mini can fill a much larger wall and do it from closer range, which matters enormously in typical home setups.

Neither unit supports Dolby Vision, so HDR enthusiasts will find the same limitation on both sides. On balance, the Beem 520 has the edge for picture sharpness, making it the stronger choice for content clarity and detail-oriented viewing. However, users with limited room depth or a desire for a truly large image will find the Beem 470 Mini more capable — its throw flexibility and maximum screen size represent a genuine real-world advantage that partially offsets the resolution gap.

For the most part, these two projectors are evenly matched on connectivity. Both carry the same wired essentials — one HDMI port and one USB port — and share an identical wireless feature set: Wi-Fi, Bluetooth, AirPlay, Chromecast built-in, and Miracast. In practice, this means both units can receive content from iPhones, Android devices, laptops, and streaming sticks with equal ease, and neither requires a dedicated network cable thanks to the absence of an RJ45 port on both.

The one meaningful differentiator is the Beem 470 Mini's DVI connector, which the Beem 520 does not have. DVI is a legacy video interface, rarely found on modern source devices, but it does provide a direct digital video path for older laptops, desktop GPUs, or certain professional equipment that still uses it. For most consumers this will never matter, but in a business or education context where older hardware is common, it adds a niche but real compatibility advantage.

Stripped of that single distinction, this category is essentially a tie. The Beem 470 Mini holds a narrow technical edge solely due to the DVI port, but only users with legacy equipment will ever benefit from it. Anyone operating in an all-modern-device environment will find both projectors identically capable on the connectivity front.

Across most features, these two projectors are virtually identical — both include a remote control, a built-in smart TV platform, a sleep timer, and a single 3W mono speaker. The shared audio output is modest by any standard; a single 3W driver won't fill a large room, and the absence of Dolby Atmos on both confirms that neither is positioning itself as an audio-first device. Users serious about sound will want to route audio externally regardless of which unit they choose.

The sole differentiator in this group is the Beem 520's 3.5 mm audio jack, which the Beem 470 Mini lacks entirely. This small addition carries practical weight: it allows direct connection to wired headphones, a soundbar, or a portable speaker without needing Bluetooth pairing — useful in quiet environments, for late-night viewing, or simply when a wired connection is more reliable. The 470 Mini's omission of this port means external audio must go through wireless channels, which adds a dependency that not every setup can accommodate cleanly.

The Beem 520 takes a clear, if narrow, edge here on the strength of that headphone jack alone. Every other feature in this group is a dead heat. For users who ever anticipate plugging in wired audio — whether headphones or an external speaker — the 520's added flexibility is a genuine practical advantage that the 470 Mini simply cannot match.
