    Be Warned!!! I am now frightened to use this. Tried it on a low power over blanket and it caused the controller of the blanket to melt. Experimented & it was only off the inverter. I don't think certain electronics like the modified sine wave.

    True. Some of the cheaper inverters will be modified. You need pure sine wave for expensive electronics

    Would this work to blow up air beds whilst camping (away from electrical hook ups)?
    Roygroyg's avatar
    Already own one so just tested on one of the wee mains air pumps (150W) and worked ok. Didn’t put it under any strain so can find they cut out if reaching limits but can often restart.

    I’ve been using mine to power some old Woolworths corded sanders and cut out once on the plate sander when switching on but restarted ok and then no issues. (edited)

    This is going to fall as the new one, with slightly more power/usb-c charger is out now.

    the new one is £99 so this seems like a good deal already

    Looks good, where is the Makita one of theses?
    NewAnonymous's avatar
    You can buy and adapter for around £18.
  5. hotztuff's avatar
    Have two of these and work them with Makita batteries and an adapter!
    Think I got them a bit cheaper than this price.....but still hot. (edited)

    For an understanding of how little this product makes sense, look at the promotional picture. They’ve plugged in a 5V USB charger to the mains outlet, meaning the 18V battery is being used to run a 230V inverter, then in a completely separate stage that mains voltage is being stepped back down to 5V DC. But the product already has 5V USB outlets built in that bypass most of this inefficient process! Yes you are limited to 2 ports and 2.4A but that’s just another limitation of this product

    For the kind of typical use cases this product will see, a USB-C power bank makes more sense

    Don’t see the sense of these 18v to 240v adapters. An 18v 5Ah battery has a maximum of 100wh so could light an old bulb for 1 hours. Maybe good for a off grid soldering iron but not much more
    Beachy87's avatar
    It's actually worse than this, when you factor in losses for conversion of 18v to 240 - a 6 amp battery is 108 Watts (92 Watts after conversion approx) meaning 100 watt load will run for 55 minutes or 46 minutes on 5 amp battery.

    Partly the reason I've not bought this as its probably modified some wave.

    I'm actually building a makita based pure sine wave inverter into a makpac box at the moment (running off 10 x 5amp batteries) after seeing something similar on YouTube

    Amazing - that's Father's Day sorted! Absolutely superb timing, thanks

    Sooner spend more money on Milwaukee

    These are great - I have two, and paid just over £50 each for them. As far as I can tell you can’t accidentally overload them - they just flash a warning light and won’t work if you try running something that needs more power than it can supply.

    Plug the charger in and charge another battery.... Perpetual power....

    Muahahahahah.....

    Reading the reviews it sounds like a low quality modified sine wave.
  13. andy_spoo's avatar
    I have one of these. It's more useful for the light and the USB charging port than anything else.
    The mains part is a bit hit/miss. Somethings it will work with but other things it will just show a red light and refuse to power up.
    Some of the Amazon reviewers are saying that this is a 'Modified Sinewav' inverter rather than a 'Pure Sinewav' inverter, which is why (other than the max wattage being exceeded) some devices don't like it.....and I'd have to agree.

    I bought this thinking it'd be handy for charging MacBook whilst in the garden. Nope, doesn't work, shuts itself off and on again repeatedly.

    Got one from amazon warehouse for 33.38 good for radios low power tvs and lights but no good for anything with a motor ( reviews amazon) 3rd party batteries are from £30ish for 5ah. Twin packs are the better option. One use for this is charging your steamdeck when out
