    Could someone who has reasonable electrical knowledge share whether I would be able to use the provided charger for the I1 with a power inverter to charge the battery? I assume that I should get one that at least meets the 3.83 amp/26.3V output. But someone with knowledge would help. I've also heard it is not always a good idea to use an inverter in that it might damage the brick somehow (or maybe certain types of inverters do this).

    Tks in advance.

    According to the info printed on the brick the input is around 1.4amp

    So If your inverter can supply around 150W A/C Output it should cover it.

    When I visited the USA last year I bought a cheap Duracell Mobile 150 Inverter. It is rated at 100W continuous and 150W Peak which may not be enough as it might overheat the Inverter.

    Blade Strike is a DJI Forum support guy and he suggested a minimum of a 300W transformer/inverter to handle the load. That usually requires direct battery connection. Won't be able to just plug it into cigarette lighter. And watch you car battery. If your car is not running, you'll deplete the battery fairly quickly.

    I have a power inverter from Walmart I always use for anything I want to plug into my car. Had a whole Xbox and tv setup on it for a trip once. No doubt it could handle multiple of these. I think it is 700w which is probably the biggest you'll get for a cigarette lighter connection.

    I've been charging with a 400 Watt Coleman Powermate in a Honda Fit while driving. It seems to charge in about the same amount of time as plugged into a normal outlet.

    It is recommended to use" pure sine wave" type of investor which is safe with electronics . I have build in PSW convertor in my truck ,and I do charge all my LiPo battery with it.

    Can you supply a link (UK) for charger?

    Thx

    The inverter I use is a Schumacher XI75DU Power Inverter. It is good for 750W and 1500W peak. Anything bigger that I have found requires a direct to battery connection. Searching on Amazon.com I found a few but on Amazon.com.uk I do not see any listed. It looks like most of the inverters sold there take the voltage to 220V for obvious reasons. It will take a little more research to find one similar.

    I saw the amazon link, and it doesn't show a cigarette plug..only the red and black posts. Did yours come with the cig attachment?
    I thought mine was big enough, but it just beeped at me and shut off when I tried to charge I1 batteries on it.

    Most vehicles have their 12v power outlets on a 15 amp circuit. At 12v, this would supply a maximum of 180W before blowing the fuse. The unit that @Mazz mentioned will only supply 750W if directly connected to the battery -- otherwise it is limited to 120W (per its user manual).

    My 140W inverter can only handle charging a single Phantom 2 battery at a time. I tried connecting two chargers and two batteries to it, and the inverter shut off due to excessive current draw. I haven't tried charging my Inspire 1 battery through the inverter yet, but if the Inspire 1 charger is 1.4A at 120V, it would require 170W minimum inverter, which is just at the limit of what most 12v power outlets can supply.

    Yes it came wih the attachment. I have plugged a lot of stuff into it with no issues so I assumed this would not be a problem. Let me load it up this weekend and I will let you know how it does. If people have tried and it didn't work it gives me second thoughts with mine.

    Charging a battery from car usually a good idea, but not works well. If battery is 125 or 150 Ah than needs to use battery charger 350 to 600 VA.

    I use a West Marine 75w inverter. (www.westmarine.com) built and marketed for boats and does the job well. Toying with packing two 12v batteries in series and simply removing all of the inverter/transformer, etc. and going straight with 24-26v source.

    You'll blow it up if you do that. The power needs to be trickle fed into the battery. Do NOT connect it straight to an unmetered 24v supply.

    For a half-day+ shoot with an Inspire 1, I'll go through (3) TB48 & (2) TB47 batteries that need to be recharged. Want to use the SPC4500 commercial-grade quad-battery charger from Smartpowercharge.com in my 2015 Honda Civic Hybrid. Smart Power Charge says to use the quad-charger in the field, I need a 12VDC to 120VAC 600-W pure sine wave inverter (like the Power Bright APS600-12). Any input on the wisdom of this approach?
