Upgraded XF40H Handheld Game Console, Retro Gaming Console Preloaded Classic Games with Multiple Emulators, 4.0 Inch 4K HD IPS Screen Open Source Linux System, Pocket Video Gaming (Black-128G)

Decent retro console with a bright screen plays lots of games, but isn’t upgradable
This portable game console is pretty good out-of-the-box, but don’t think you’ll be able to play every game included on the micro sd card that comes with the unit. Still, there’s a lot of great games here.Let’s take a look at the hardware. There is a good sized 4 inch diagonal screen that is bright and reasonably responsive. The screen feels like it has real glass covering it (not polycarbonate). The unit also ships with a screen protector that you can put on if you want. Using the screen protector is probably a good idea if you plan to just throw the unit into a pocket or purse with the also included case.The unit has a 4-core CPU and separate GPU. It isn’t going to win awards, but it’s capable of playing nearly any game I tried quite well. Some games have sound glitches, but I think that’s the emulator and not an issue with the hardware.Speaking of sound, the built-in mono speaker is quite loud and doesn’t distort. That being said, it’s not going to impress any audiophiles. If you don’t love it, you can always use standard wired headphones (via standard 3.5mm jack).There does seem to be ~4 GB of internal storage that is used only for boot up, and not for game storage.The included 128 GB micro SD card is mostly full. So while you can put more games on it, don’t expect to add a lot more. Most of the storage on the card contains the “20,000+” claimed games. I haven’t counted all of the games, but there are quite a few across the 20 emulated systems. The card itself is cheap and I don’t expect it to last long. I purchased a high quality 256 GB micro SD card and used my laptop to copy over the data from the 128 GB card onto my new one and then I packed away the original for safe keeping. It’s worth noting that you’ll need to format whatever card you want to use in Fat32 format for it to work. The documentation also says that the largest card the hardware can read is a 256 GB card. I didn’t try using something larger than that, but I can confirm a 256 GB card works well.The rumble pack in the unit is pretty powerful and seems responsive. It also seems to work well with the games that support it.The shell and gaming buttons are plastic. Not the cheapest I’ve ever used, but not super-premium feeling. However, none of the buttons feel particularly mushy or loose, so that’s good. That being said, I don’t love the small shoulder buttons. They are too small to be easy to hit. The analog sticks feel ok and move smoothly. The LED lights around the sticks feel gimmicky, but are bright and have several color options (and you can turn them off).The software that runs the unit is ok. It contains a variety of cores to emulate everything from stand-up arcade machines (via a variety of MAME cores) to the earliest gameboy or NES. You can disable cores that you don’t want to use and you can adjust which core each game rom uses. This is good, because not all games will launch or play using the default settings.While the unit does ship with a basic manual accessible while using the unit, it doesn’t cover all features, so you’ll probably want to make a note of some of the more esoteric key commands that you can find in this listing on Amazon, because they aren’t easily discoverable otherwise. There’s also a small insert that explains how to hard reset the device if it freezes up (this is an emulator console, after all).I find the battery life to be ok. It will run for hours in my testing. It charges via USB-C (and it includes a cable, but no wall charger). It’s not the fastest charging unit, but I found it to be ok. The battery is not designed to be user replaceable, unfortunately. And from what I saw from a teardown, it’s not the easiest to replace (though it could be done if you can find the right battery).The included case is slightly hard, so it should protect against average drops.This unit does include WiFi and Bluetooth for multiplayer games that support it, but you cannot upgrade the software on the unit over the internet. There is a GitHub repository with software updates you could manually install if needed, but the unit I received shipped with the latest software installed. I don’t know how often (if at all) there will be updates, but you should assume there won’t be any. Don’t expect bug fixes to come along.The unit also does not have an HDMI port, so easy connection to a TV or monitor isn’t in the cards.For the price, you get decent hardware that can play a ton of games right out of the box. So long as you don’t expect a user-replaceable battery or regular software updates, you should have a lot of retro-gaming fun on the go.

Fun alternative to the expensive one
We bought this for our oldest, youngest son (long story) and he loves it. It fits in his hands well and is very similar to a PSP. There are lots of games on it and he plays quite a few of them. The graphics are good and the battery lasts a while also. We recommend this

Great product overall
This is a great device to play on if you want some old nostalgia like NES and older games. Even has an N64 emulator which is cool. Now the problem is there are games that are extremely laggy like i was playing God of qar on the PSP emulator and its slow amd laggy. Most of the games on the PSP and playstation emulator is laggy which sucks because those are my favorite. Also games like Gauntlet legends and killer Instinct on N64 are slow and laggy as well. I dont know if its my system or maybe im doing something wrong but other than that. Pokemon games are good. The DS games are good and everything else. Great device for the price.

Straight garbage
Piece of junk, laggy, have to reboot to exit game. Buttons don’t do as displayed. Stay away from this product. Totally unsatisfied with this product. Should be removed for false advertising. It went into brick mode after two days. Do not buy this.
