Onson GP18迷你投影仪In-Depth Review

If you want to enjoy watching a movie, there have never been more options than there are today. For picture quality, nothing beats a large LCD television. For convenience and portability, a simple smartphone is where it’s at. But if you want a fuzzy, nostalgic, old-timey feeling, a home movie projector is an excellent choice. Better yet, even a top-tier projector comes at a lower cost than an HD smart TV. It’s also easy to move from room to room. All you need is a blank white wall or a projector screen. There’s no installation required.

But which home projectors are worth your money, and which are not? Anyone can produce a low-quality projector, then follow up with outrageous claims that it’s the best thing since sliced bread. No worries. We’ll help clear things up for you. We’re about to review the Onson Mini Projector, a compact, portable projector for home use. It comes at a reasonable price, and is compatible with a wide variety of inputs. But is it the right choice for you? We’ll take a look at all the Onson projector’s features, from its video quality to its physical construction. After that, all you need to do is decide whether or not to click that “buy” button. Let’s get started!

总体设计

顾名思义，Onson GP18迷你投影仪（使用代码“ 70BQ9U66”以70％的折扣）is relatively compact. At 11.2 inches wide, 7.9 inches deep, and 4.3 inches thick, it can be stored just about anywhere. And at only 3 ½ pounds in weight, it’s easy to transport. You can throw it in a backpack and take it to your friend’s house to enjoy a movie together.

大部分结构是白色的ABS塑料，覆盖了投影仪的前，顶部和背面。它具有吸引人的光泽饰面，可抵抗涂抹，易于保持清洁。在投影仪的正面，您会看到镜头，该镜头是由四层抛光玻璃制成的。它位于黑色腹部外壳中，并具有光泽的饰面，以补充整体案例。在镜头外壳旁边，有一个配套的光泽黑色面板，上面有银色的onson徽标。在此面板中，您会看到一个小的LED灯。当投影仪打开电源时，该光线会激活，因此您知道您已经准备好了。

On top of the projector, behind the lens, there are two ribbed black dials. These are used to make keystone adjustments, which we’ll talk about more in a minute. Towards the back of the top, you’ll find a control panel with eight rubbery black buttons. These buttons control all of the Onson projector’s functions. The up, down, left, and right arrows allow you to navigate the menu, where you can make even more adjustments. If you prefer to use a remote, Onson has you covered. A remote is included with the kit, with a white finish that matches the projector. Throw in a pair of AAA batteries, and you’re good to go.

The left and right sides of the projector consist of vented black panels. The sides should be kept clear during operation, to allow for free air flow and cooling. On the left, there’s a two-prong power connection for the projector’s AC adapter. On the right, you’ll find all of the inputs. At first, this unorthodox placement might seem odd, since inputs are typically located on the back. However, it’s convenient if you’re keeping the projector on a shelf with its back against the wall. You can still swap out inputs, without having to move the unit around. On the bottom of the unit, there are small rubber feet that prevent skidding or scratching.

除了Onson GP18本身外，您还可以获得一些额外功能。该套件包括一个令人惊讶的坚固耐用的尼龙携带箱。它有足够的空间容纳整个套件，包括遥控器。盖子上还有一个拉链口袋，上面有手动和电缆的空间。还有一个小三脚架。它不是为了支持整个单元而设计的。相反，它旨在倾斜投影仪，因此您可以在地板上将其放在地板上。您甚至可以获得HDMI电缆和RCA电缆，用于连接设备。最后，您获得了一年的制造商保修，可保护您免受零件或制造的缺陷。

The Onson Mini Projector is portable, but it’s not pocket-sized. If you want a projector that can literally go anywhere, you’re going to need another option. In that case, consider theCanon Rayo S1。It’s about the size of a cell phone, but it’s not very bright. So you can only use it in a dark room.

视频质量

Onson迷你投影仪格外明亮,with a brightness of 2,400 LUX. This means you can use it under just about any lighting condition. It won’t work in bright daylight, but that’s to be expected. It will, however, work in a room that’s lit by normal lightbulbs. In addition, it offers a 2000:1 contrast ratio. This number refers to the difference between the brightest and darkest tones on the screen. In general, a contrast ratio of 1000:1 to 3000:1 is considered good. Below 1000:1, it can be difficult to distinguish different tones of the same color, particularly blacks. Anything above 3000:1 is superfluous, since the human eye can’t make the distinction. So at 2000:1, the Onson GP18 is quite good.

Onson迷你投影仪使我们失望的一个领域是图像解决方案。它的本机显示分辨率仅为800 x 480像素或480p。换句话说，您没有获得高清图片。您甚至没有获得720p图像。也就是说，它仍然支持最高1080p的输入。该图像将仅将其缩小到480p。换句话说，您可以观看蓝光光盘，但不会获得蓝光质量。

If you need 1080p quality, you’re going to need a more powerful projector. If that’s what you’re looking for, check out our review of theVANKYO Performance V630 Full HD Projector。IT在True 1080p中投影视频，因此您可以从蓝光播放器中获得全部好处。另一方面，它往往会有点热，因此在运行时保持双手清晰。

纵横比可以是16：9或4：3。第一个是高清视频的标准配置，而第二个是旧电视节目的标准配置。无论如何，Onson Mini投影仪将根据输入源自动调整长宽比。当涉及图像大小时，这将取决于您的投影仪离屏幕多远。在32到170英寸的任何尺寸上都清楚且无模糊。为了获得最佳质量，Onson建议将投影仪定位为距屏幕3米（约9.9英尺）。在此距离处，对角线上的图像将为100英寸。

The Onson Mini Projector has a pair of built-in 3-watt stereo speakers. The sound quality is very good, without any distortion. You won’t have to worry about high or low tones muddying up the middle frequencies. The highs are shimmery and clear. And the lows are nice and punchy. With that being said, these are 3-watt speakers. They can’t put out very much volume. If you want louder sound for a larger room or a party, you’ll need external speakers. On the other hand, this is a projector, not a sound system. The fact that it has any speakers at all is a nice added value.

Operation & Compatibility

正如我们已经提到的那样，Onson GP18迷你投影仪易于操作。您可以使用遥控器或板载控件来管理所有功能。不需要智能手机应用程序。此外，放置非常容易。您可以在垂直和水平上调整15度的基石。结果，您可以将投影仪放到侧面，向下放在地板上，或将其安装在天花板附近。这比您从这个价格范围内的大多数投影仪获得的多功能性要多得多。

Another good feature of the Onson Mini Projector is that you can play video from almost any device. For most purposes, you’re going to want to use an HDMI cable, which is included in the box. That said, since the image is only 480p anyway, you can also use the RCA input for older devices. For computers, you also have plenty of options. You can use an old-school VGA cable to connect, or use an HDMI cable for newer systems. In addition to these options, you can also play video directly from an SD card. Admittedly, many people won’t use this option. But if you’re watching home videos from a smartphone, it’s quick and easy. You can even play videos from a USB thumb drive. The Onson Mini Projector supports most video formats and codecs, so compatibility should rarely be an issue.

最终判决

So, how does theOnson GP18迷你投影仪（使用代码“ 70BQ9U66”以70％的折扣）与班上的其他人相比？让我们从不足的地方开始。480p的决议令人失望。当然，这不是高级投影仪，但至少很高兴看到720便士。另一方面，亮度非常好。在照明房间里看电影不会有任何问题。对比度也很好。在2000：1，您将能够区分各种音调，而黑暗的场景看起来也很棒。

The control scheme is simple and intuitive. Use the buttons on the projector, or use the remote. Either way, the menu is easy to navigate. Finally, there are more inputs than you’ll know what to do with. You can watch video from just about any source, from your PC to your thumb drive. You can even play video games. Provided you pair it with a pair of external speakers, the Onson Mini Projector is an excellent choice.
