What SD CARD should I buy?

If you want an SD Card for your camera - these are the ones I use and recommend. 

I'd strongly recommend not to buy any SD cards off ebay - I've heard about too many issues with counterfeit cards - often sold on by unwitting resellers. My inbox regularly gets messages from people who bought a £150 camera then cheaped out and bought a £3 memory card on ebay - Then when it doesn't worth they blame the camera! It doesn't make any sense. Good memory is cheaper than it's ever been - see the links above.

A lot of HD cameras will not work properly with cards larger than 32GB (cards over 32GB are usually SDXC rather than the SDHC standard used by 32GB cards. SDXC cards use the ex-FAT system rather than FAT32 - in short they are a different standard). - so don't just buy the biggest card you can afford - read the specs in the manual to see what it accepts.


RECOMMENDED CARDS (for action cams - see dashcams below)

CLASS 10 UHS-1 CARDS (For HD Cameras)


U3 CARD (For 4K cameras)




The SD card in a dashcam is re-written over, more frequently than in other types of cameras. Some manufacturers void their guarantee if an SD card was used in a dashcam. So, no surprise, there are special High Endurance SD cards made just for's some.


VERY IMPORTANT. These links take you to the product, however Amazon have three different ways of selling. There's Amazon Direct - This means that you are only dealing with Amazon themselves, then there's other sellers that use Amazon's facilities - these show as Fulfilled By Amazon and finally there's Market Place sellers that advertise on Amazon, but operate independently.  I strongly recommend that you only use the first...the Amazon Direct - Sold By Amazon option. Even if it appears that you are paying a couple of £/$ more it is more than likely you are comparing the price of a real item against the price of a fake.

To give you an idea of the extent of the fake goods problem. In a 2016 survey by Apple - 90% of the 'Apple' chargers sold through Amazon - using the other the two methods..which includes the "Fulfilled by Amazon" option -  were found to be counterfeit....90%!

You can power a Dashcam via your OBD port - But perhaps you shouldn't


Watch the short video below to see this demonstrated.

Make sure you read the youtube comments as a number of people there explain why powering something from the OBD port is a bad idea...and then a few more people say that it should be fine, there's no problem.

It's really your decision as I just don't know enough about auto electrics to categorically confirm either camp is correct. 

You can obtain OBD to USB power leads from the links below:

Love your reviews and have communicated before about heat problems with dashcams.

so, have you any views on the "new" Hyundai H92 Dashcam, very big,good features and maybe should not be affected by heat problems?

The specification of the OBD II connector (SAE J1962 specification) says:

"5.3.9 VEHICLE CONNECTOR TERMINAL 16 - Vehicle connector terminal 16 is designated Unswitched Vehicle Battery Positive and must be implemented in the vehicle connector. This terminal must be connected directly (i.e., unswitched) to the DC Positive of the vehicle's battery. This connection does not preclude the use of a fuse or other circuit protection elements. This circuit may be grouped with other similar circuits. This terminal must be able to supply a minimum of 4.0 A."


"5.4 Vehicle Connector Terminal Protection — It is recommended that the vehicle manufacturer provide circuit protection in the event that the terminals of the vehicle connector are shorted together."

So yes, the OBD port's power pin (battery positive 16):
- MUST be unswitched (always connected to battery power)
- MUST be able to handle 4.0A
- SHOULD be protected via e.g. a fuse

So except for the fact that you could drain the battery, connecting a dash cam to the ODB II port should not give any problems.
