I've had a bunch of Bluetooth keyboards kicking around for ages ( I suspect at least two years ). I've only used a couple of them a couple of times, so I've finally decided to give them a quick try-out - so I thought I'd put those reviews up here in case they turn up in an online search and someone finds them useful. But they have been sat in the To Do pile for quite some time, so make and model are best guesses.

Note that I just typed on each one for three lines or, while sat properly at a desk, within two feet of the Android phone I was using for testing.

If anyone's intrigued by any of these but wants to confirm whether:

  • they remain connected for more than a few minutes
  • can they hold a charge for a day
  • they have any specific functionality you're after for Unix / terminal usage
  • the specific placement of specific keys

do say so in the comments and I'll figure that out.

Some crappy Bluetooth thing off eBay

Bah, I can't find this in my order histories online, it looks like this:

I don't know this specific make and model so all I can say is to avoid the really cheap stuff. While this did appear to replicate what I typed on the screen it has a weird double space bar, the keys feel genuinely awful, and the USB power connector is Micro A.

Anker TC320

So that'll be this one: https://www.amazon.co.uk/Bluetooth-Ultra-Slim-Aluminum-Keyboard-Windows/dp/B00BKW2410 - do note that searcher for this model will actually bring up a newer version.

Works nicely on my Android phone, pretty big size, and I had this one relatively loose in a large bag, so the middle is something like 2mm higher than the edges, but it still works. OK if you want a decent size keyboard, but you'll want it in a firm bag.

EC Technology Foldable Keyboard

I think it's this, or close enough: https://www.amazon.co.uk/EC-Technology-Foldable-Ultra-Slim-Aluminium-3-Folding-Keyboard/dp/B00QRQZQR8/

This is reasonable enough to type on - it's essentially a "meh" keyboard, which is the best you can expect from something portable. Also it folds up nicely and appears to be suitably rugged, so something that will slip into a pocket or smaller bag.

Note it doesn't have a right CTRL key, which just might be important to you. Also the layout is, er, American, I think.

Zoom Bluetooth Keyboard - Series 1087 - Model 9010

Pretty sure this is this one: http://www.zoomtel.com/products/9010.html ... hmmm, this was left on a low power charger ( 500mA or so ) overnight, then left switched off for a few days, and had no charge left. It has a row of media keys along the top, with what I think are a "home button" key and a "lock screen" key.

Seems rugged enough too, not sure about that charge going away. Also bear in mind the power socket is USB Mini-B, not Micro-B.

Periboard-805

A bluetooth foldable keyboard - which will look like this:

.

The key positioning is too weird on this one - the EC Technology foldable keyboard is OK because it folds a quarter of the way in from either end, this keyboard folds in the middle - which means the centre of the space bar I tend to hit is the join, the right shift is in a weird place, and the placement of the keys in the middle detracts from ease of use. Only the foldable keyboards will fit in the smallest of my bags, along with a phablet and a spare battery... so I like the idea of them, but they don't seem to work in practice, at least without spending more money.

Palm Universal Wireless Keyboard
