    This video introduces you to the compact but powerful HIMCEN H740P 740 Watt Hour portable power station. The H740P will be out for sale soon and boasts several unique features compared to similar power boxes on the market.



    Disclaimer: The HIMCEN H740P power station review sample was provided to me free of charge.

    The H740P has a removable battery pack that can be separately charged. This feature allows you to expand the power storage capacity greatly. Additionally, the HIMCEN boasts a speedy recharge time. As little as 2-3 hours! Other interesting perks are a 100W USB-C charge/discharge port and an XT60 30 amp DC output port for charging RC planes/cars and drone battery packs.

    I give you a close look at the nicely designed battery pack, the specs, how it is removed and reinstalled, plus a couple of quick demo tests. Starting with a heavy load test. I max out the power station's 600-watt pure sine inverter, and I see if and how long it can power my little True North electric heater set to 600W mode ( 1 hour and 5 minutes).

    Then I try a full recharge using the supplied AC power adapter outputting 200 watts ( a little over 3 hours). If I were to add a 100W USB-C charger, the charge time could be reduced even more since the two charging inputs can be used simultaneously. A terrific feature.

    Stay tuned as I will soon have another video out with more in-depth testing and demos of the HIMCEN H740P power station, plus my full review. The H740 Pro price is listed at $899, but the word is there may be a significant introductory sale when it hits the market.

    I wonder how much the output voltage goes down- especially towards the end of the battery capacity.

    Hi Ray,
    Happy new year, hope you and Ann are keeping safe.
    I tried to register for the news letter and any updates on the product however when i tried, it keeps giving me an error.is something wrong with the site? This is something i would really be interested in . Is it the PRO model you tested ?

    I'll test it with my Kill-A-Watt meter on some things and check the voltage and amperage at various stages of dishcharge

    I gave it a try just now and it worked for me, maybe they were working on it, I know that the owner said they were going to have the launch site up in about a week. Looks like they will be giving 20% off.

    Finally getting some clear sunny weather here on the coast to complete my review.
    It can take up to 300 watts of solar panel input. Should have a second video out soon

    I have been giving them lots of feedback on the box. Mine is an early model so they can improve things based on my experiences before the launch.
    Two issues I've seen so far are:
    1) The folding solar panel they have doesn't live up to the wattage claims. Seems to underperform versus the Jackery 100W I have, even though it claims to be 120W. They outsource that though so are interested in my test results.
    2) When the battery pack is at a lower capacity say around 25% the inverter output voltage on heavier loads drops below 110VAC and much lower than I'd like in the 103VAC range.
    They say they can adjust that with a software setting. They were erroring on the side of caution trying to not overheat things. But I informed them some items may not like that low of a voltage. It's almost like a brownout. The nice thing is its a small company so I'm actually talking to people about the design that actaully build the thing. Cheers, Ray

    OK! I’m back with my full review of the H740 portable power station from a company called HIMCEN. This new power station has several unique features, which grabbed my attention when HIMCEN offered me one of their early units for review. Like the XT60 port, for example, I haven’t come across before in other portable power stations I’ve reviewed.

    But, top of the list in my mind is the lithium battery pack being removable, allowing for expanded power capacity. Another essential feature is the speedy recharge times. A downfall of many of its competitors on the market.

    Would be interested in knowing how many nights you could get using a CPAP machine
  • Ray

    That's a tough call as different CPAPs use differing amounts of wattage, I guess depending on how much they cycle and some people use the humidifier and some don't. The HIMCEN website estimates 52 hours run time for a CPAP

    CPAP machines don't cycle during their use. The compressor , humidifier and heated hose run continuously . My CPAP power supply is rated for 1 Amp at 110 Volts . This power source should be able to a CPAP or a APAP without any issues.
    Question : How can you feed 100w thru a USB connector? That's about 20Amps at 5 VDC or 8 amps at 12 VDC.

    Thanks for the info.
    It's a newer type of USB port called USB-C that supports different chargers and devices. It can go up to a max of 20 VDC 5 amps for 100 watts of power.
    Here is an example of a 100W USB-C charger https://www.amazon.com/Nekteck-Certified-Foldable-Charging-Compatible/dp/B089FC1TRF
    A lot of the newer laptops use them for fast charging.

    Thanks ray. I forgot about the USB-C standard . USB-C is also the same as the Thunderbolt 4 connector that Apple now uses on laptops.
