Bought an 800W one today. Not sure how well it will connect to batteries but meh, I'll work it out.

Spent the last few days planning and getting stuff ready for camping trip, now the person hosting it is sick and whole thing falls apart day before leaving. What the duck do you do now? Me and the Mrs still go camping and have a mad NYE partying in the bush? Lame

Modified sinewave = good for basic appliances that aren't interrupted by fluctuations in power delivery

Pure sinewave = computers and complicated electronics, as has less static from a smoother sinewave

The rest of the thinking is just making sure the inverter has more (constant, not peak) watts than the appliances running off it.

electrical theory is what i do for a living. think ive got it sorted thanks.

and i dont get people complaining about laptops on inverters. laptop chargers are switched-mode power supplies turning AC to DC. the shape of the wave (unless its particularly shitty) should have little affect on its charging. my dad drove melbourne to Perth using a cheap 300W inverter for laptop, no dramas.

The one we got did a good job at charging phones... but the Macbook Air charger (white brick) made a buzzing sound it doesn't normally do and charged about 50% slower than normal...

We were suprised that the 6 berth campervan we got didn't have any 240v outlets, so we grabbed one in NZ from a Dick Smith Electronics. Connected it up to the Deep Cycle "Home battery" under the seat in the camper. Lovely.

Edit: Note to self, don't try to bring one back into australia with your carry on luggage... It looks very very suspicious when it goes through the bag scanner :P Got pulled aside and asked for inspection

    • Yes, I know🙄 but the sequential is not in my budget... don't want to reduce power neither, so looks like I'm stuck in the rabbit hole🤣
    • You’ll be very upset when you bust that too not to mention the gearing totally sucks. Don’t do it.
    • Is the panel filter one that is oiled? Have you ever cleaned or touched the AFM?
    • So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch
