Based on LCD technology, the Caiwei A7 WIFI device delivers 665 ANSI lumens, a resolution of WXGA 1280 x 800 and a contrast of 5000:1 as a projector. The LED unit of this model is rated for up to 50000 hours of runtime – calculating to 34.2 years at four hours of use per day. To make performance data comparable based on the lumen specifications, we calculated an approximate ANSI lumen value. Regarding projection size, the value of 665 ANSI lumens allows for an image width of up to 262 cm in darkened environments. In rooms with ambient light, the image width should be correspondingly reduced to a maximum of 175 cm. For media input, video signals up to 1080P are supported. This model dates back to 2017 and is no longer part of Caiwei's current product range.

Bringing such a product onto the market shows criminal malice!
One star for the connection options, which is why I bought the projector in the first place. But that‘s the end of the positive features. Not much else works. The supposed Android 6.0 only has the user interface and the file structure in common. Essential Android functions are hidden. Pre-installed apps cannot be updated and are therefore unusable (youtube, happycast, amazon, netflix, file explorer, twitter, facebook,...). Even the playstore is a proprietary creation and cannot be updated. The search is very limited. Many apps do not work from the outset. Manual installation of apks does not work either. The operating instructions are a joke. Picture and sound dropouts every few minutes. Cannot be operated without your own wireless keyboard, etc, etc, etc. The service team contacts you immediately after purchase, but cannot help. They are probably too stupid for the technology. Questions are simply ignored. The update that was sent to me is older than the original firmware! Is it still working? They supposedly don‘t have the original firmware. Shake your head;-( Conclusion: it works even less than before... And I‘ve saved the best for last: the last time I enquired, I was advised to connect a TV stick! Because it works better... Any questions? That‘s just the way they are, the intelligent Chinese... Hands off WIKISH and CAIWEI!!! It‘s just annoying.
