300watt power inverter

[Jimquested]

I’ve picked up the 300watt power inverter below to run off the leisure battery when we don’t have an electric hook up. The idea is for it to power a small projector. Has anyone used these before? Any risks to damaging the leisure battery / circuit? Thanks for any advice.

cheap Chinese MSW cloan inverter.

be warned - it wont have a fuse in that plug.

so don't pull more that 80W from it or it will (if pklugged into a T6 12v socket)

A - possibly melt the plug/socket
B- blow the socket fuse.

to go from the 100-300w range it needs to be clipped dirtect to a battery.

if you want a decent one. . . I've got a couple of these and they are great . . plus PURE sine wave.

again for 100W plus it needs to be clipped to the battery.

Thanks, that’s really helpful. Think I’ll send this straight back. Sorry to seem ignorant, how would you clip it straight to the battery? Would you snip off the 12v connector and then bare wire with some terminal clips/ rings? Add an inline fuse?

Yes exactly that

what He said.

you can also get high power 12v unfused socket to croc clamps. . . that what i used to do.

but then swapped that out for fused SB50 Anderson connectors.

As a thought if you have a number of your power boxes you don't need to have all the power in one place and distribute it at 12v the way you do 240v, you can have small zones around a power box.

That may make more efficient use of the stored charge.

This is the way I run the event PA, each amp point has an 18l Really Useful Box with 40Ah or so of SLA in on Andersons

we have done something similar before, at summer camp. . .



the main van + Tent was setup with.

twin 100ah battery boxes, 400w solar and the Anker 757.

note that:

although they are 300W,

you can only pull arround 100W - 150W from the 12v socket, before the vans fuse will blow.

the Bestek plug IS NOT FUSED so it can handle more power , but will heat up.



we use them in conjunction with these . . .

I’m not a fan of 12v plugs for prolonged current draw, it’s ok for occasional/short term use but they can get hot, if you are running something like that a pulling a reasonable current I would get a decent direct connection via a suitable fuse
