The best all-in-one portable projector is the one that makes all the right compromises. It needs to balance image and sound quality with battery life and responsiveness in a device that’s not too expensive and small enough to take anywhere. TCL’s fun little PlayCube delivers the right mix to justify paying $800 for a 1080p projector in 2026.
I tested the TCL PlayCube running Google TV during a two-month road trip, and then again for a few months at home. It’s so small, adaptable, and enjoyable that I’ve had no problem setting it up at a moment’s notice, day or night, anywhere I’ve been.

$800
The Good
- 3 hour battery in brightest mode
- Clever, twisting design helps placement
- Bright for its size
The Bad
- Sluggish at times
- Standby power weirdness
- Mono, muddy sound
TCL says the PlayCube’s 90-degree rotating design was inspired by the Rubik’s Cube. Just give it a twist whenever you need to lift the image over obstacles. Otherwise, you can mount it on a tripod via the threaded connector at the bottom, or flip it over onto its backside for some bedtime ceiling viewing. The PlayCube also features all the automatic adjustment modes you’d expect in a modern portable projector, including focus, keystone correction, obstacle avoidance, screen detection, and eye protection.
The other notable thing about the PlayCube is its brightness. 750 ISO lumens isn’t bright for a home theater projector, but it’s very bright for a portable that easily fits into the palm of your hand, measuring 149.8 x 96.6 x 96.6mm (5.90 x 3.80 x 3.80 inches) and 1.3kg (2.7 pounds).
It’s bright enough to watch videos during the day when all those lumens are focused into a tight 30-inch rectangle inside my van, or at 100-inches when projected against it at night. Unfortunately, it doesn’t have that color-adaptation tech found on Samsung’s new (battery-less) Freestyle+ projector, so the blue-gray hull affected the palette. Regardless, it was still very watchable.




The audio produced by the PlayCube’s lone 5W speaker is fine. There’s no stereo separation, but it’s loud enough to fill a room. It just lacks fullness, warmth, and detail. Music from Florence and The Machine and Kendrick Lamar sounds shrill and thin. The screeching tires, gunshots, and explosions from a 007 chase scene produced a rather muddled soundscape, but it was still enjoyable. The sound is uncomfortably harsh above 60 percent volume, which is still plenty loud. During one outdoor movie night, I felt compelled to set the volume no higher than 20 percent to avoid bothering the closest neighbor some 50 meters away.
Alternatively, you can connect headphones or self-powered speakers through the audio jack or over Bluetooth. The projector can also be used as a Bluetooth speaker, which turns off the lamp but, annoyingly, not the fan. That fan produces 27dB when measured at a distance of one meter, which is fairly quiet for a projector but still noticeable during still moments.

The runtime from the PlayCube’s 66Wh battery was inconsistent, but it performed very well in recent tests. TCL claims up to three hours – I measured exactly three hours and one minute after a full charge in the projector’s brightest mode, while streaming The Aviator over Netflix, a film that runs for 2 hours and 50 minutes. It also works with USB-C power banks if you need even more time. The PlayCube recharged from zero to full in 104 minutes from a 65W USB-C charger.
I experienced wild shifts in battery life over my four months of testing, which I think can be attributed to TCL’s power management in standby mode. A short press on the power button puts the projector to sleep, allowing it to wake in less than 30 seconds. In standby, the fan spins up periodically, sapping energy — which could be the reason I saw severe battery drain when vanlifing in warmer climates. The issue disappeared when I returned to the mild temperatures at home. A firmware update might have also helped.
Regardless, you can long-press the power button for a full shutdown to avoid any phantom power drain suffered in standby. The PlayCube then takes about 80 seconds to boot up, but that can be accelerated by turning off some of the automatic screen adjustment features.
1/13
The user interface can also be sluggish at times, like most battery-powered projectors. Sometimes Google TV needs a frustrating second or two before it’ll respond to navigation commands from the remote control. The automatic image adjust features are also rather slow to kick in. But I’m grateful when they do, even if obstacle avoidance can be hit or miss. Fortunately, everything can still be fine-tuned manually.
TCL says the PlayCube is “designed specifically for camping projection.” That makes me — an avid vanlifer — its primary target, and I’ve come away very impressed. At $799.99, TCL’s PlayCube projector isn’t cheap, but you won’t typically find this mix of brightness, battery life, and portability for less. Xgimi’s Halo+ comes close for the same price, only in a bigger package that offers improved stereo sound but shorter battery life… but it’s currently on sale for just $449, which is a very good deal.

![Scientists Say Some Black Holes Are Born From Other Black Holes
Since LIGO’s Nobel-winning discovery of gravitational waves—ripples in spacetime—the U.S.-based detector has been picking up on hundreds of signals from black hole mergers. And, after a decade of studying gravitational waves, researchers believe a significant fraction of black holes may come from cosmic chain reactions. A recent paper published in Physical Review Letters describes an analysis of 155 pairs of binary black holes, identified by LIGO and its sisters, Virgo and KAGRA, in Italy and Japan, respectively. According to the study, about 14% of merging black holes may be what’s called “second-generation black holes,” or black holes that form from previous mergers of two smaller black holes. This “hierarchical” backstory is vastly different from the textbook version of how black holes emerge from the explosive death of a star. “Overall in the universe, black holes are merging all the time,” Cailin Plunkett, the study’s first author and a graduate student at the Massachusetts Institute of Technology, told MIT News. “Now we’re seeing a relatively consistent picture where there’s a decent percentage of black holes that are coming from this repeated pathway.”
Tracking the invisible Gravitational waves that reach Earth’s detectors typically come from extremely intense events. Over the years, LIGO has picked up some truly perplexing signals. For example, last summer it found the most colossal black hole merger ever—and if that wasn’t wild enough, the black holes that took part in the merger lie within a cosmic “dead zone” for black holes.
This zone refers to a range of black hole masses in which, physically speaking, black holes can’t form through ordinary stellar collapse. From these discoveries, astronomers realized just how little we knew about black holes, which are challenging to investigate directly. In that sense, it was a no-brainer that the ever-growing catalog of LIGO’s gravitational signals would turn up entirely new insights about black holes. “It is increasingly clear, both from individual events and population analyses, that massive black holes exist in [this] range,” the researchers wrote in the latest paper. “These observations have spurred further investigation into mechanisms that can populate this gap.”
A wobbly imprint The latest research represents one such investigation. During mergers, the two black holes spiral toward each other along an orbital plane. When one or both black hole spins are misaligned, the orbital plane can wobble, or “precess,” the researchers explained to MIT News. The degree to which the disk wobbles acts as a parameter from which researchers can measure the masses and spins of the merging black holes. One telling sign of hierarchical mergers is that they’re “lopsided,” meaning one of the pair has a much higher spin and mass than the other. For the study, the team created an analytic model to capture the kind of wobble that would have emerged from second-generation black holes. Around 14% of merging black holes followed this pattern, and the second-generation black holes identified had a very specific range of masses, at around 20 solar masses or 40 solar masses and above. Of mysterious origins To be fair, that might not sound like a whole lot. But it demonstrates that a sizeable portion of known black holes indeed follow this pattern. As for why, the team suspects hierarchical mergers emerge from dense stellar environments. Simply, when multiple neighboring stars die and collapse into black holes, the dense environment can make it easier for those black holes to find each other and merge. That could further lead to the formation of second-generation black holes. Theoretically, this could “repeat potentially ad infinitum, by virtue of the fact that you have a ton of stars and black holes in this really dense environment,” Plunkett said.
But an ensuing mystery concerns those black holes in the 40-and-above regime, which coincides with the aforementioned “death zones” for black hole masses. According to stellar evolution theory, black holes born of supernovas shouldn’t leave any black holes above roughly 45 solar masses, explained Plunkett. “Yet we have seen black holes that are that massive,” she mused. “And the question is: Where did they come from?” For now, it’s hard to say when we’ll get an answer to that question, if ever. But one thing seems to be clear: black holes are a lot weirder than we could ever imagine. #Scientists #Black #Holes #Born #Black #HolesBlack holes,Gravitational wave,LIGO Scientists Say Some Black Holes Are Born From Other Black Holes
