I have a Pi 4 coming over the next couple of days a d see the official PSU is 5v 3a. I already have an ifi Ipower PSU that is rated at 5v 2.5a, would I have any issues using this with its lower rating?

Just make sure you're not connecting any USB-powered peripherals to your Pi (like a DVD drive that isn't self-powered), and you should be fine.

Will be plugging in a Dragonfly Red and a USB memory stick:)

Memory stick will be fine, but you could be pushing it with a Dragonfly Red. It's best to check...

I have found most kit takes about 50% of the rating of the psu supplied with it.
One of these is really useful to see how much your kit is actually taking https://www.ebay.co.uk/itm/LED-USB-Current-Voltage-Charging-Power-Detector-Tester-Volt-Meter-Ammeter-TR/153294016645?_trkparms=ispr%3D1&hash=item23b1091085:m:mLrefoQUEcZ4JH7Dt-bCPyQ&enc=AQAEAAACUBPxNw%2BVj6nta7CKEs3N0qUUnSGTikjWEGlq cN0j33sQS%2BoWZU%2BXYg0tpj%2FDqFw8th4TwueqnnLAR%2F WzZUCwL%2Fz%2BhjJm0KOBuBKREOGjbDwm%2F7ZCrNtWFcMcCO SsxZB0%2BlGMvJWOvkHGEVrpZZKBBdy8w03bzUXVToJSKTIDJJ dW62l1UQbjHwZ9RMsMJy5ZOPkxpOoPH69KZB%2FA6BGiiLkN5U cHyfpwLLDlRkV%2Fraa141NWrHDrbchlLRWjvRiQHSGGP1dCsd ryR4lE%2BPI%2BvEseBgB4MTCeUktF%2Fy3u34bFcTmnb4hObL j5A2dstnMRigSnzSMlxzTa73Azb3F51%2BFl%2B9DsxXwoMTMQ M1c6KeUQUTAqmdlBNSdzGtC8lZbHaGd68FG%2FBpDRMRXCRbhH %2FFZaNqnChrjOTw8bpinTOczfGL0UoFY1sOzriBZsX%2BWojT N%2B8BWomvwWrC1mycmVOIycm482m%2BccduJTdszeAJKXWOo9 OJoywa7fpZU3zu7mfQq4k0uN2zpRXbjPTQI60DO1mh4J5GEST9 qC7KcEJAnZSOnVEufoLRfCWncV9Bwy38PT6aDsbd%2Fhaixupb JIlG%2BosOkXj3yLa9zhcLGyZTG2sz1yjuODWGEzc%2BWWZM5L f913uXSaXg8LKr8s2YrqBJtIhX9tvoeJm%2BG7H3eubp9BFpjY YYh7q0eR2cMacXdKveY50r6hhSpnQls6sDW5r%2F%2FDqMt3mN MYjPwyrQK4w1%2F%2FqcWzMvn5oJQ237qCnJuTNRKhbuqGH8jy ODPk6uRN7lY%3D&checksum=153294016645610bc45c52914a048fe8db2b67423 a78

That's good to know. Do you have any 'hats' attached or is it simply a base Pi-4?
Made in 1968

It's a Pi-4 with an Audioquest Dragonfly Red and a USB memory stick attached.
