Safe, yes; useful, no.

The cigarette lighter sockets are only energised when the car is on, which means that when the car is off (as in the case of a flat battery) there is no pathway for the jump starter to get power into the 12V battery.

Thanks Herbie ,therefore I shall purchase a gooloo 3000a for my rx450h 2021 assuming I have the right 12v Battery for such an item 👍

Related, I got one of these as a present a year or two ago

Never really had to use it in anger until last week though I did keep it charged up in the time I've had it. Should have read the instructions properly as they will not start a totally flat Battery. I found this out trying to get the Subaru started after one of the kids left the interior light on for 3 or 4 days. But tbh even the more meaty one my local garage loaned me wouldn't start it either. New Battery required.

You're very welcome Paul and the Gooloo lookslike a good choice. No need to worry about your Battery, these jumper units work on all batteries. I've got a Tacklife T8 and I've used it on lead-acid and AGM without any problems.

EDIT: One thing I would say is to get one with a digital readout of how much charge is in it. Mine is reading 90% even though it's been sitting in the car (unused) for a good 9 or 10 months. Of course, the idea is that you don't get caught out so I do try to remember to charge it every 6 months or so, and now that I've realised that I'm late, I'll do it this very afternoon.
