Accessories Android portable projectors

[today]

Hi all. Looking for some input on portable battery powered wireless connectivity projectors. I am very interested in having one that would be able to project my computer screen and/or cell phone screen to a 8ft projection on a wall. Are these requests impossible. I've just started to investigate and wondering if someone on the forums is already doing such things.

You won't get a very bright image if you want an 8ft projection on a (white) wall, you'd need total darkness in the room to see it. Those lottle projectors are more about giving an A4/A3 size image to share with a small group of people. those small projectors tend to have a limited native resolution (320x480, 640x480, 800x600 but not much more than that

Here's an example on EBAy UK http://www.ebay.co.uk/itm/Wifi-Wire...alaxy-S3-S4-/291054152111?hash=item43c42de9af

Here's the specs that matter:
Resolution: 640 x 360 (nHD)
·Projection Image Size: 10"~60"(Diagonal) With that resolution an image much over 12@ diagonal will look very blocky.
·Focus: Manual
·Brightness: 50Lm (Max)

Here's what I've been using:
http://www.ebay.co.uk/itm/2600LM-Ex...c0fabd5&pid=100005&rk=2&rkt=6&sd=151570637317

Claimed 2600Lm (Lumens) - Bright enough to use in daylight and with a better resolution of 800x600 - but it's AC powered.

50 lumens is not very bright at all, and I think that's about all you're going to get from an internal battery powered projector TBH. Any brighter, it has to be mains operated, and 640x360, that's like really low definition, especially for projection, it's not even SD.

I have one of these...which is mains powered, and bought from a friend who works for the manufacturer.

It's 350 lumen, which from my uses I project to about 6-7ft size in subdued day with it, window blinds closed. And its native resolution is 1280x800, which is quite nice. And it's small and light enough to put in the laptop bag to take places.
