Regrettably they also have a two pin version so you can guarantee that however it’s wired there is an even chance of either pin being connected to line

That you are making incorrect statements. Not a way that an electrician would phrase it since the circuit of course is feeding from both sides however for a non electrician specially one who doesn’t actually know electrical theory a way to describe it. But of course you wouldn’t understand that. Well yes it does rather matter on the hardware you buy. I showed a socket that has polarity on the flat pins. I have, and have seen, many that are unpolarised and have no markings to indicate wire orientation, so while your electriction’s mind may be deeply offended few care or pay any attention to what should be be That the vast majority of flat pin plugs that I have seen, and have, is completely relevant. If you have always used unpolarised plugs you will naturally assume that this is the “standard” and as such you will have a 50/50 chance of wiring sockets “the right way” All you have to do is read a few of the many reports here to know the truth of that The majority of “electricians” working in domestic wiring have no technical training or certification. You have to work in the real world, not the idealistic one where things are always correct. Of course you should but the truth is that it’s a 50/50 chance that it’s been done correctly and a very good chance that it will never matter.

Exactly as my post, though I didn’t check that the airline specifically designates 5 volts as the calculation voltage so 20K is the limit. The maximum voltage is not variable, neither is the calculation voltage. The limits are based on the maximum capacity not on the capacity of a semi-discharged unit, so YES your semi-discharged unit at 3.1v would not be permitted Not to the regulations, it isn’t. A useful one NO but it still has the potential to be one again so YES it IS a spare battery according to the regulations. From some of your posts it seems that you are very much more confused than I ever am From the above argument your acceptance isn’t as clear as you suggest. The 100-160 Wh hour limit is generally the same for all airlines BUT it is often a requirement that you get permission for carrying the batteries before the flight in fact you seem to have not noticed, even though you posted the link, that the calculation is based on 5v and that even for Thai airlines you are required to notify the check-in staff.

Diddly I pity your sleep. I have no idea of what your nightmares are made of however the only things that need a little attention are the battery terminals, as if you try hard and drop a piece of metal across them you could short them out. But explode! Individually 12V in circuit 24V. The wiring is unit -> battery -> battery -> unit with a voltage indicator across the input/output wires so whatever is causing your nightmares you should either stop or change the medication Yes they are on my list though not very high.

Look at the 3rd picture in my post on page 1, since you seem to have some difficulty in being sure of details, it is not the picture with the cat and TV but the one with the yellow CyberPower box. The CyberPower unit in picture one usually only runs a single router and Ethernet switch if the power cut is a long one. Your belief is as unimportant. The fact is that the batteries have lasted during a 4~6 hour power cut and it is a very simple, though not exactly cheap, to add further capacity.

Where the is an appliance where the line neutral need to be oriented then you should never use a 2 pin socket, only ever direct wired or 3 pin socket where the line is correct wired for the orientation of your appliances.

If you are wiring as a ring circuit (a circuit that though common in the U.K. should never be used) then yes you can that depends on the hardware you buy. I have Thai hardware where the coding is the same as the US style, and yes yet is Thai hardware as the 3 pins are round. Also if you orient the socket in the correct way when vertical with the earth pin at the top then they are US style. The correct orientation is line at 9 earth at 12 and neutral at 3 Obviously there is no danger as the Thai flat 2 pin plugs are gender neutral They very rarely have switches and only a fool would use a single pole switch where the L and N are easily reversed.

The limit is actually 27,000mAh (100Wh) without getting permission from the airline, so 20,000 mAh power banks are a safe bet.

I don’t have a condo. There is no nearby network operations centre. I have had power cuts ranging for minutes to several hours, my internet supply did not get cut. So your vast knowledge is sadly lacking and your predictions that I will lose connection has not proven true yet, and may never be. I wait, but won’t hold my breath. I have no need for the noise, smell, disruption and bothersomeness of a generator. My setup silently (apart from warning tones) runs the necessary equipment for several hours and with batteries with more capacity can do the same for days

There are 2 Apple Stores in Bangkok all the others are Apple Authorized Resellers

Your upstream devices may go down/off. My provider has backup power, so, so far I have never had a power cut to my house effect my fibre connection. So that is the point

Your purpose may be to do that, however mine is to keep the minimum units, routers, Ethernet switches, security cameras & NVR, running for as long as it takes, potentially hours.

Your information is incorrect. The limit is actually 27,000mAh (100Wh) without getting permission from the airline and you can have several, this is why the 20,000 mAh power banks are popular. With airline prior permission you are allowed 1 or 2 X 160Wh batteries. So you were lucky that the airline allowed your over sized power bank on board. It is irrelevant if it is charged or discharged and lithium power banks are never permitted in checked baggage. Laptop computers are allowed in checked in baggage but it is a poor idea to do so given the treatment of some checked bags. There are special measures on cargo aircraft for carriage of lithium batteries and lithium batteries in devices.

Actually the limit for airlines is slightly higher than 20,000 mAh rather than 10,000. my suggestion is the Orson eloop there are several models available in stores and from Lazada This is mine and I’ve had it for a couple of years. one point is make sure the capacity is clearly marked on the power bank or it may be taken from you by security.

The purpose of the IDP is to provide a translation into several languages English is only one of them. Many, not all, countries will accept a license (like the Thai one) that has English as part of the license without requiring an IDP. The U.K. accepts a full Thai license. It does not accept the temporary 2 year license and you can’t get an IDP using a temporary license.

That is an incorrect statement. I have a design, copied from a Nepalese builder that is around ฿15,000 for the deluxe version, probably under ฿10,000 for a smaller one. You are probably basing your assumption of cost on the use of vacuum tube versions that are required in higher latitudes and are north of ฿60,000. We are in a latitude where a far more simple, probable un-pumped, setup can do an adequate job.

Not necessarily, the possession of a pink card/yellow book doesn’t grant any knowledge of where they are, and are not, accepted. The acceptance is variable and not known until tried.

CyberPower UPS is value for money and quite a bit cheaper than APC. They also have a two-year on-site guarantee I’ve had technicians come out to my house in the middle of nowhere twice. This was for battery failures. However, replacing the battery is really quite simple and remarkably inexpensive, Batteries are about 175~ 250 baht for one and you need two for the UPS this is the one approved by my cat for keeping her router powered and warm, it also powers the TV This is another in the range, you can drop in price for lower power and then this gets rather more expensive but powers the security system and several computers AFIK all cyberpower UPS offerings can shut down your computer if the computer is windows, the shutdown may also work on Mac, I have never configured it so can’t comment on the functionality but it is in the SW.

I agree that sometimes simplicity is good, however our tanks and plumbing means that we can virtually never be unable to get water. It would have to be over a month of the village water being cut. We also are always able to shower. It would have to be several days of power-cut to exhaust the ready-use tank in the roof. So the one downside is that the roof tank isn’t sun warmed, but we could add a tank on a flat roof we have and connect the already installed warm water plumbing. I would be far more likely to get round to making a passive solar heated system, I already have a design and some of the plumbing, it is just my supply of rountuits has never got high enough to be top priority. All in all the benefits of my setup vastly outweigh the single downside.

Since the picture has dry concrete (cement sand aggregate) and is significantly more expensive than the individual items you can’t find it here. The pictured wall while easy is much more expensive than the volume of concrete it contains. That said you could just stack bags of cement they will harden but have not much structural integrity or strength, they will also be vastly more expensive than the idea of filling rice bags with dry mixed concrete.

That may work for you and your plumbing. With us it doesn’t as the storage tank is in the roof so daily temperature changes have no noticeable effect

That is certainly one reasonable way to power them. However a non electric version would probably be far more economical hear due to hot sun.

If you get a stored water heater it will still use the same amount of power BUT it will run at a much lower amperage just for much longer, so 2.5mm sq cable is ok

While absolutely true, I can attest to the fact that they function with much lower pressure than is comfortable for a shower. I can throttle the pressure to a flow that is so low that it is virtually impossible to use it as a shower but can get 44C temperature.

I can virtually guarantee there is no functional difference, it is just the form factor
