How to freelance in a boat on a lake?

Question

Freelance

I am a freelance programmer.
I work mainly from a laptop, as a portable device I use an Android mobile phone (battery 4000 mah) in order to quickly respond to clients when I go, for example, on a bike or swim in a boat. Phone with a very bright screen and a matte film that allows you to work even on a bright sunny day.
There is only one problem - the actual range of tasks performed from a mobile phone is very limited - but actually only negotiations with clients and planning current tasks. There is no question of performing tasks, programming.
In this regard, I would like to take a laptop on the boat so that you can relax, freelance and at the same time not limit yourself in the tasks you perform. But any normal powerful laptops have a problem - the battery lasts for a maximum of 2 hours, in this regard, I want to take an uninterruptible power supply (plus a set of charged batteries) into the boat.
But the uninterruptible power supply essentially performs a voltage conversion of 12--> 220 - in connection with which the question arises - and not a shock of current - especially if it rains or splashes water (in this case, a sealed bag has been prepared for the laptop to protect the laptop from water ingress )?
How likely is it that it will shy away - if the boat is not iron, but rubber? And how dangerous is this - after all, the maximum current output by an uninterruptible power supply is still not the same as in the outlet (but much less)?

Answer 1

laptops have external batteries. Accordingly, the voltage is there as an input. one battery can extend the life of about 2 times.
plus you can try to solder them in a plastic bag for water resistance.

Answer 2

A rubber boat, freelancing, a laptop are incompatible things.
This is simply dangerous not only for the equipment, but also for you.
If you still want to swim longer with a laptop - you need something like a portable power station. The simplest thing is to charge the solar battery. https://www.amazon.com/X-DRAGON-Charger-Sunpower-N...

Answer 3

A normal powerful laptop lasts for eight hours, the time for two hour laptops has already passed.

Answer 4

I don’t know what kind of laptop you have and what kind of power supply it has, however, the power supply of my laptop personally gives 20 volts at the output. What kind of 220V you are talking about in your question is not clear to me.
A voltage of 20V is quite capable of producing solar panels. I saw on the net somewhere knapsacks with built-in solar panels. I think if you twist them a little, solder the output or connect through an adapter, then it is quite possible to power your laptop. Google "Solar charger" and buy a soldering iron.

Answer 5

Put the motor on the boat, and hook up a dynamo to it to generate current.

Answer 6

An uninterruptible power supply is not needed - conversion from battery DC to AC 220 volts, and then reverse conversion with a laptop power supply. It's just a waste of energy. Not to mention the fact that 220 volts is dangerous on the water.
Check the voltage on the laptop power supply.
Assemble an assembly of batteries of the appropriate voltage.
Add a stabilizer (sold ready-made in radio parts stores).
If you are very afraid, then all this can be filled tightly and tightly (batteries - separately, power supply separately).
If there is not enough money - a lead battery (automobile, motorcycle)
If there is enough money then - LiFe
If there is a lot of money - then it's easier to use a branded spare laptop battery (2-3 pieces as needed).

Answer 7

If there are electric eels in the water, you can recharge from them!
In general, what prevents you from buying a laptop with an operating time of 8 hours or more? Macbook, Soft Surface to help you.

Answer 8

"any normal powerful laptops have a problem - the battery lasts a maximum of 2 hours" - Macbook to help you.
When I took mine, in 2014 it lasted from 7 to 12 hours. Depending on the required tasks.
Now it lasts for 5-9 hours. But he is already 2.5 years old and works every day from morning to evening.
PS The current strength above 0.1A is already deadly for humans.

Answer 9

Take a normal laptop from Apple, or bring along a 12V 30Ah battery and a 12V converter to the desired voltage.

Answer 10

If the boat is covered, then you can safely take a charger for a laptop on a solar panel and use it and not know grief)

Answer 11

If the author is a programmer in a boat, then he will not want to waste his time on troubles.
Option 1 - buy power banks for laptops, press them, and use them. The fastest.
Option 2 - make a power bank to order, for example, in an electric bike workshop. Perhaps it will be usable.

Answer 12

Get a bigger boat if you like working that way. That's how this guy did it .
