As freelancing in a boat on the lake?

I'm a freelance, programmer.

I work mostly with a laptop, as a portable device using mobile phone on Android (battery 4000 mah) in order to quickly respond to customers if food, for example, bike or ride a boat. Phone with very bright screen and the matte film which allows you to work even in a bright Sunny day.

There is one problem only - the actual range of tasks with the mobile phone is very limited and actually only talks with clients and planning tasks. On the implementation of tasks, the programming of the question.

In this regard, I would like to take the boat laptop to be able to relax, freelancing and it does not limit itself to the task. But any normal powerful laptop is the problem - battery lasts max 2 hours, in this regard, I want to take the boat uninterruptible power supply (plus a set of charged batteries).

But an uninterruptible power supply essentially converts voltage 12-->220 - in this connection the question arises - and not weird shock - especially if it rains or gets a spray of water (in this case laptop prepared with a sealed bag that protects the laptop from water)?

How likely is that still there is a boat if not of iron, and rubber? And how dangerous it is - because the maximum current given by the UPS is still not the one in the outlet (and much less)?

Solution
for laptops there is an external battery. accordingly, the voltage there as input. one battery can extend the life time of about 2 times.

plus you can try to solder them in cellophane pack, for water resistance.
Yes, the real option, in principle. Other normal variants and no. - Daren27 commented on July 2nd 19 at 17:19
: actually, search on Power Bank Laptop - Cullen commented on July 2nd 19 at 17:22

Rubber boat, freelance, laptop is incompatible.
It's just dangerous not only for technology, but also for You.

If you still want a longer swim with laptop - You need something like a portable power plant. The simplest way is charging the battery on solar. https://www.amazon.com/X-DRAGON-Charger-Sunpower-N...

+1, better yacht :D - Daren27 commented on July 2nd 19 at 17:21
try underwater boat, more questions will be added :)) - Cullen commented on July 2nd 19 at 17:24

Normal laptop powerful enough for eight hours, two laptops time has passed.
A good laptop costs 100 000 - but this and the boat will take pity. And the usual thousands of 30 (for work) just keeps those same 2 hours. - Daren27 commented on July 2nd 19 at 17:23
: well, take the cheapest Mac it costs less than a thousand dollars if I remember correctly. - Cullen commented on July 2nd 19 at 17:26

I don't know what your laptop is and what his included power supply, however, the power supply personally, my laptop outputs 20 volts. What about 220V You say in your question is not clear to me.

A voltage of 20V is quite capable of delivering solar panels. I saw online where the backpacks with embedded solar panels. I think if you give them a little tweak to resolder the output or to connect an adapter, it is possible to power Your laptop. Google for the phrase "Solar charger" and buy a soldering iron.
Don't know, tried to solder. In General, it turns out - if some thing is broken (but can be repaired), and then I'll try to fix it with a soldering iron - then sure you should be thrown out. - Daren27 commented on July 2nd 19 at 17:25

Put the motor on the boat, and to him pick-up a Dynamo to current to develop.
220 and water - incompatible. Yes, and the boat with the motor (plus laptop), one will not have to carry. - Daren27 commented on July 2nd 19 at 17:27

The battery backup is not needed - convert from DC battery to AC 220 volts, and then inverse transform the laptop power supply. This is just extra loss of energy. Not to mention the fact that the 220 volts is dangerous on the water.

Check the voltage at the laptop power supply.

To assemble the Assembly of batteries of appropriate voltage.
Add stabilizer (sold ready-made in stores electronic components).

If you strongly fear, that can all pour and tightly sealed (battery - alone power supply separately).

If money is small - lead battery (car, motorcycle)
If you have enough money that LiFe

If money is a lot easier brand laptop spare battery (2-3 pieces needed).

If the water is home to electric eels, it is possible to recharge them!

In General, what hinders to buy a laptop with a working time of 8 hours or more? MacBook, Melkomyagkie Surveys to help you.
MacBook will not work - you need Windows. And all laptops work time 8 hours expensive (and if you search only on the basis of the battery capacity - other specifications will be incorrect - for example, the touchpad or keypad keys are not uncomfortable). - Daren27 commented on July 2nd 19 at 17:31
: and the battery and Akuma that you are going to buy it not expensive???
I have about servicebook from Microsoft also wrote - Cullen commented on July 2nd 19 at 17:34
Yes, and on the MacBook it is fashionable to put vinly - logan66 commented on July 2nd 19 at 17:37
I don't know, but the battery to bespereboynik cheap - like 1000 rubles apiece only. Laptop and UPS is already there, no need to buy. - Neha.Waters commented on July 2nd 19 at 17:40
: this is all very expensive work. This laptop would be a pity to take the boat. Need cheapest option. - Daren27 commented on July 2nd 19 at 17:43

"any normal powerful laptop is the problem - battery lasts max 2 hours" - Macbook to help you.

When taking your, and in 2014 worked from 7 to 12 hours. Depending on the required task.
Now it is enough for 5-9 hours. But he is 2.5 years and is open every day from morning to evening.

PS current above 0.1 A is already deadly to humans.
To 0.1, provided that the current passes through the body, and not somewhere nearby. the human skin also has a resistance. - Daren27 commented on July 2nd 19 at 17:33
MacBook will not work - you need Windows. And I actually have a laptop (chose easy to operate and not to allow the battery kept a long time). More than 40K on the laptop to spend are not ready, not a millionaire, and there are already laptop - why buy more? - Cullen commented on July 2nd 19 at 17:36

Take a normal laptop from Apple, or get a 12V battery and 30Ач Converter with 12V to the required voltage.
Yes - important to 220V without an intermediate voltage. - Daren27 commented on July 2nd 19 at 17:35
if from shore is not far away you can just a long extension cord to take the wire from the water will be nothing, for then you will have unlimited electricity) - Cullen commented on July 2nd 19 at 17:38
: and still advise to buy the boat, especially if you're a good freelancer. Now it is possible without problems to buy for 8000$-15000$ - logan66 commented on July 2nd 19 at 17:41

If the boat covered, then you can safely take charge for a laptop on a solar panel and using it and a grief not to know)
or just plug the charger into the side Jack. why TS so stupid? - Daren27 commented on July 2nd 19 at 17:37

If the author is a programmer in the boat, then spend your time on stuff he doesn't want.
Option 1 - buy powerbank for the laptop, a message their and use. The fastest.
Option 2 - make powerbank to order, for example in the workshop of electric bikes. Might be usability.

To get a bigger boat, if you like to work. That's how this guy did.
