Humless Go Mini Information

The Humless Go Mini fuelless generator system with a lithium battery and 1500 watt pure sine inverter is capable of running off of various renewable power sources, such as hydroelectric power, wind turbines, solar power, and even off the AC power in your homes. It is able to run any type of hand-held device or laptop as well as larger appliances such as refrigerators and washers. It was designed as an alternative to generators that use gasoline, propane or other fossil fuels for different emergency situations or remote operations.

“Our home base is definitely with the emergency-based crowd. It’s like a power supply in your pantry,” “The simplicity of it helps people. It’s nothing to be scared of.”

The system is very portable. At around 35 lbs it can be taken almost anywhere. It’s dimensions are (LxWxH) 17.75″ x 10.2″ x 12″.  It is also ‘humless’, which should be taken literally – it makes almost no noise, as well as no gas smells/messes or other harmful emissions when being used.

With the Humless Go Mini come these included accessories:

  • An AC power cord used for charging
  • A master power switch that turns on and off the system for short and long term storage. When the power is off the Go Mini can remain on a shelf for a year before needing to be charged again.
  • When the unit is on an LCD battery level meter and time remaining display shows
  • A removable shoulder strap is included.

This is a very compact system for its power capacity and is designed with all its controls and plugs easily accessible on the top of the unit. It can be used with USB device, household AC appliances and tools, 12 volt auto accessories and also has Anderson Powerpole connectors for higher DC current demands such as those needed by amateur HAM radio operators.

  1. Dear Humless Sentinel Team,

    I have a few questions, and would be most grateful if you could please answer them as best as you can:
    1. would this generator be sufficient for running a very small modest home or basically a fridge, and a computer and modem, and occasionally a washing machine, and/ or an iron.
    2. is it quiet
    3. what is its life span
    4. how long does it take to recharge through AC opposed to solar
    5. postage costs / are there import costs as we are outside US and UK

    Kindest thanks in advance,

    • Q:1. Would this generator be sufficient for running a very small modest home or basically a fridge, and a computer and modem, and occasionally a washing machine, and/or an iron?
      A: Yes and no… the Sentinel can run a fridge, a computer and modem, a washing machine but not so much an iron. However, it won’t run all of them at the same time or with the same charge. You could run a fridge for a few hours before the battery would be discharged and would need to be recharged. Same for a computer and modem. I’ve done three loads of laundry on a single charge using my energy efficient front loader washing machine plugged into a Sentinel. The issue will be the time needed in between running one of those devices to recharge the battery by some means before you can use it to run another device.

      Q:2. Is it quiet?
      A: Very, especially compared to a gas generator. The loudest sound is a cooling fan running when the Sentinel is being charged by it’s AC charger or the inverter’s cooling fan when large wattage devices are being run. The fans do make noise but you can hardly notice it over the sound of talking.

      Q:3. What is its life span?
      A: The life cycle varies depending on use and is related to the battery and how often it is charged and discharged. The cycle life of the battery is rated at about 2000 charge cycles. The other longevity issue is time itself as all batteries decay overtime from the day they are manufactured. The LiFePO4 battery chemistry should last 7-15 years depending on use storage temperature etc. What you can expect approaching 2000 cycles or 7-15 years is a reduction in capacity. Brand new the Sentinel’s battery has a capacity of 50 Amp hours. As it approaches the limits it’s capacity will slowly diminish. At 2000 cycles the capacity will be about 20% less than it original capacity. In other words it will still hold a charge just not as big a charge.

      Q:4. How long does it take to recharge through AC opposed to solar?
      A: The AC charger pumps between 15-20 amps into the battery during charging which will take about 3-3.5 hours to charge an empty battery to full. A solar panels charge time will depending on a few conditions. A 100 watt solar panel which under full sun will produce about 5 amps peak will take about 10-12 hours of full sun to recharge the battery. If your solar panel is smaller or larger wattage wise it will take more or less time. If the weather conditions are cloudy it will take much longer too. You can also use more than one solar panel for a quicker charge.

      Q:5. Are there import costs/postage costs as we are outside US and UK?
      A: Depending on the dealer US postage might be included in the price or cost extra by about $30-$50 to ship within the US as the Sentinel weighs about 41 lbs by itself. The cost to ship a Sentinel to the UK is about $165 based on weight (not including insurance) from the West of the USA. I would recommend buying it from as most people I’ve heard from have the best experience with them.

  2. Dear Humless:

    I recently tried my fuel-less generator for the first time. I plugged in a space heater and it worked fine. Later I charged my generator with the AC input for about two hours. Afterwards I plugged my space heater back in and turned it on and the red light on the output switch came on and the same heater that worked before would not work. Is it overloading? Why would it do that when it worked fine before I charged it? Did I make a mistake by leaving the red key in the on position while charging? If so did I damage it? Please help, I will need this heater if the power goes out.

    • There’s a few things we need to address with your issue. Some will help you get going but the last will be an eye opener.

      First, I don’t think you damaged anything but to correct the problem you are having, you do need to have the red key turned on when you are charging your Humless Sentinel otherwise nothing will get charged and the two hours you had it plugged in will have done nothing. The red key should be turned on for any task such as charging or using any of the power output options on the Sentinel. Do turn the key off when the unit is in storage or not being immediately used or charged.

      With the red key turned on you should hear the fan in the Sentinel’s charger turn on and it will be quite noticeable that something is taking place. An empty battery should take about 3-3.5 hours to recharge fully and once done the unit will go quite and you can unplug the power cord.

      Once the battery is charged the Sentinel is ready to be used for the task at hand. The Sentinel’s inverter can output a 1000 watts of power continuously however, most electric space heaters can and will use much more power than a 1000 watts when running on their HIGH mode which is likely why the Sentinel “tripped”. If your heater has a LOW mode it may have worked fine when plugged in initially to the Sentinel and that’s what I’m guessing allowed it to run before it was charged.

      Lastly, I need to address the pros and cons of using and electric heater plugged into the Humless Sentinel. As you found at one point the Sentinel will power and run an electric space heater assuming the heater only draws less than a 1000 watts of electricity. It’s great to have a power pack like the Humless to do this however, (and this is the eye opener I warned about) the battery capacity the Sentinel has won’t run an electric space heater for much longer than 40 minutes to an hour before the power inside a fully charged battery is all used up and won’t run it any longer. In other words, a space heater’s power consumption is so great it really needs more power than a Humless Sentinel can provide for extended heating use. Electric devices and appliances in general that generate heat such as a space heater, hair dryer, slow cooker, hot plate, or heat gun use a lot of power very quickly making it difficult for the Sentinel’s battery to provide power for those devices for longer than about 40 minutes or at all if those devices use a HIGH mode that consume more than a 1000 watts of electricity.

      There is one heat option that will work for the Sentinel for an extended amount of time and that would be a 12v type electric blanket.

      A 12v electric blanket, one that uses about 50 watts or less would give you 10-12 hours of heat from a fully charged Sentinel. Here’s one that would do just that:
      For a true back up room heating option you might look at a direct vent propane or natural gas radiant room heaters which work without electricity but will need a fuel source. There are also portable propane or kerosene room heating options but you do need to crack a window for using those in a room indoors, and you need to store the fuel for use when needed.

      I hope that helps you get things working!

    • No, they can not be connected together to increase the power output of the inverter or the capacity of the battery. They are designed to work individually only.

      The new Humless units however, can already produce 1500 watts of pure sine wave power with a peak surge of 1600 watts for 5 seconds which lets it start even the bigger motors and compressors just fine.
