Hmmm...  85W (at 12V) gives a current of about 7-8 amp through the car 12V socket. Fuses of 15 to 20 amp for the car 12V socket should not result in a blown fuse. Something else is a-foot here. I wonder if anything else, but the car/cig 12V socket, also gets its power from/via that fuse...

The different types of charge sources/methods for the Jackery, does NOT all provide 100W of power. This is why it will take a different number of hours to charge the battery, depending on the type of power source being plugged into the Jackery charge port/socket. The MPPT stage of the Jacker...

Does the Jackery 500 not show how many watt's are going into the unit, when it is being charged? How many watt does it say that it is being charged with? How long does it take before the 15 or 20 amp fuses blow, when you try to charge your Jackery in you vehicle? The wiring in modern...

Some AC power tools use the sinewave aspect of AC power, when regulating the speed of the tool. If the inverter is not a pure sinewave inverter, the speed regulation may not work properly, so for some AC power tools,  you might only get power on/of operation, where you are used to be able to...

We have used radio frequencies for many purposes, for many, many years. But the higher frequencies have only been used for about 50 years. I am not sure what frequencies some of the mentioned natural and artificial EMF units are operating at, but I think frequencies make a difference. In...

Yes, once the battery is at 100%, then what ever comes in from the solar is just wasted. One way to make use of what is coming in via solar, once the battery is at 100% - is to charge your other appliances, like laptop, USB power bank and what ever else has a battery built in.

According to this chart, https://www.powerstream.com/Wire_Size.htm then 135 Amp is what one can safely expect to continuously draw over a 4AWG wire. So a max of a 135 amp fuse is probably a good idea. How many AmpHour are your batteries? And are they Lead Acid batteries? The only...

You might be aware of the placement of the big fuses, but just for clarity, I have added placement of the big fuses, that will protect your main wires, to your drawing. The principle is, to place a fuse close to the Plus of any power source.

For understanding the concept, of using solar to charge batteries, then the math is correct.  And looking simplistic at how batteries are charged, then it is also correct. However, when a battery comes closer to a full charge, then it is no longer able to store up the energy, at the same...

Hmmm...    It seems that the Toyota Highlander has a power save feature, where the engine shuts off, when stopped at a red light. Perhaps this is why there is also an automatic shut-off function, for your 12V ports (and maybe this shuts off the USB ports at the same time). The whole system...

Hmmm... it might help if we had some links to the items you have/are using. Otherwise it is a bit difficult to examine if there are specific details about each product, that might have caused the results that you are describing.

I think that USB-C PD is still such a new standard, that it will simply take a bit more time before it is widely implemented. Also, general USB has the advantage, that it is still low watt (5V x 3A = 15W), so it is fairly easy (and cheap) to make chips that can deal with 3Amp. At 60W, you...

Another example of watts, is about a cell phone. The battery in a cell phone is often around 3000 to 4000 mAh  (milli Ampere hours). milli is 1/1000 So 3000mAh = 3Ah The voltage of such a battery is about 3.7V So the watts stored in a cell phone is something like: (Volt x Ampere = Watt)...

Did you come across the formular that says: Volt x Ampere = Watt If you can convert the power used (or stored) to watts, then it might get easier for you to evaluate things yourself. For instance, with a 12V (AGM) lead acid 100Ah battery (where you only use 50% of the energy = max50Ah...

Very interesting video.  Awesome idea with the card box boxes. I do however think that the biggest giveaway, is when he climbs into the back.  If anyone sees that, I wonder if people will have any doubt, that he is trying to sleep in the car. Where as, if he pulls into a parking spot, and do...

There are two separate heating systems. And each system is regulated by its own thermostat. So if you were to activate both systems, at the same time, then the water would just heat up faster. For some more details, of how the two thermostats work, you might want to look at the first few...

For your information: Energy use at 5V and 2 amp is 10W. The formular is that: Volt x Amp = Watt With a 500Wh battery, 10W usage will last for up till 50 hours. And yes, you divide the watt hours of the battery by watts of the device to get running hours.

Hmmm... are you aware that voltages needs to be added (summed up) when putting solar panels in series? The AC/PV charge port specs are: Open Circuit voltage(OCV):16-69V / Max.10A, Max.500W The three max numbers to be aware of is: Max 69V - adding OCV voltages of the panels, the sum must not...

Did you look at reviews of that there HP ProBook 445 G7 14", to see if they tested/verified any battery life data? In this (lengthy) review, they talk about the battery life. https://www.notebookcheck.net/HP-ProBook-445-G7-laptop-review-Moving-forward-with-Renoir.483145.0.html Back in...

It might be a good idea, to know what degree of tilting is generally recommended, where you live/park. Where I live (way up north), this is the general recommendation of tilts at different seasons. For comparison, here is the generally recommended angles for Arizona I found these...
