Please don't even think about that for UK systems.
First, there is no earth (ground) connection, so unless the equipment is double insulated (ie, designed not to use earth), it will be unsafe.
Second, you have no way of knowing which side is line and which is neutral. This should not matter with double insulated equipment, but if the wires are coded brown and blue, then they should not be reversed.
If there is an earth (green/yellow) wire, or a three-pin plug, on the equipment, you MUST NOT connect via a two-pin plug.
All these problems (and probably others that arise with (mis)using electricity outdoors, are unsafe and potentially life-threatening. "Temporary use" does not make it safe and is not an excuse.
For any use of mains electricity outdoors, unless you know and understand the wiring regs (BS7671), consult a qualified electrician.
Er yes, but most dc power bricks with a cord even in the UK will be 2 wires, and quite often connected with an apple-esq figure of 8 2 pin plug terminating their feed. But Yes Dont leave equipment thats earthed hanging without an earth connection..
Perhaps i made too many assumptions regarding where the OP was starting from. Assuming competence to wire a plug/connector safely, and employ suitable bits n bobs.
Any power bricks used should also be boxed in weatherproof/waterproof with cable entries and exits glanded and sealed. with feeding and exiting leads positioned with natural drips away from the containment.
Any flex expected to sit under sunlight and UV should also be sleeved in a suitable uv proof conduit or ducting, NEVER tack mains flex along the top of a fence/wall, one too many summer days exposure and a casual grip on the fence top could be fatal..
but with a post connection drip point before the flex is led off to its destination and diligently wired when connected to a suitable psu (dbl insulated-
fed by a figure-8 2pin lead is a giveaway), drawing 2-3a max. Is probably a lot safer than climbing up step ladders to connect in the first place.
'Temporary' refers more to something legal to fit as a consumer under what i know as 'Part P regs' as temporary installations (i read that as meaning at the end of a plug...) are excluded from the requirement to be fitted by a certified fitter. Make a permanent connection with a junction box and you will need to get an electrician in to fit it, So you may as well get a dedicated 16a feed terminated with an ip68 comando socket installed
