GPS Locator for Car Security: Recommendations, Battery Options & Known Suppliers

hello I plan to buy a GPS locator for the car, that as "the neighborhood is not interesting" and the car will be standing outside looking for some decent device, I would like to connect it, possibly a small motorcycle gel battery or something similar to work after disconnecting the power, no unless the device has a good power supply, can you recommend something specific from the well-known auction portal or other supplier (preferably a link), or maybe a store from Katowice, I will add that I'm completely green in this matter.

You need to buy an old "ajfon", replace it with a new one and permanently connect it via a 12V USB charger for car installation. You buy the cheapest SIM with data transmission to the phone. You create a free account in iCloud and log in to your phone. Then the phone and cables are packaged in a secret place in the car, where the signal is not damped by the sheet.
And ready, whenever you want to log in to iCloud from every PC, and in a few seconds you can locate your phone with the vehicle. After disconnecting the power supply, the phone will work a few more days on its own battery (smartphones in the sleep keep their batteries really long).
I gave Apple's example because I know this system. If there is any similar software on the android, there is no obstacle to use it.

and something more professional, you can recommend

Look for a man, boy, and consult here. These devices are thousands on the market. for example,

I have this:
https://www.gearbest.com/car-gps-tracking/pp_234072.html?wid=27

And that's the problem, there are hundreds of them to buy, crap easily, I thought someone would recommend something and give me a link, because I do not want to give anything, I was not accused of advertising

I gave you that I use for over a year and it's ok. Super easy installation - you program from a computer and then stick it in the ODB2 socket in the car.

Locator in a place as visible as ODB? Does it make sense at all, in addition without its own power supply?
I thought about something like:
1. http://allegro.pl/localator-gps-server-gratis-bateria-do-3-lat-i6492115175.html
2. http://allegro.pl/lokalizator-gps-teltronic-kontroluj-swoje-auto-i6053724346.html
I will be immediately blamed for inserting links.

Gentlemen, did anyone have to do with the device from the link, and maybe say something about it?

Hello,
I have some thoughts and I have already started realizing my idea.
I purchased a GPS tracker for a dog and a cat by Tractive for about PLN 220. I do not give a link so that someone does not think that I'm doing advertising for a company. It is a tiny, waterproof box attached to the collar of a dog. It has a GPS receiver not LBS (those interested in the subject know the differences) This system has an integrated sim card in the chip that logs into the mobile phone network practically all over the world and sends position data to the smartphone application. Of course, not for free. You have to pay the company a subscription, but not much. I chose a basic subscription with 5 Euro and I paid for 1 month. which in the version for 2 years costs less than 4 Euro. It cost me 20 PLN for the time being. I hope that this body is enough for testing. For now it's ok. Works. For the future I do not intend to pay a monthly fee if I do not need to use this system. And now my idea:

I want to mount it in a car in an invisible place and connect it via a charger (one for a smartphone) to a car battery. The device works without charging for up to one week. And now the most interesting: I am counting on not paying a monthly fee to the company when it does not need to use the device. However, if something happens, for example car theft, I pay a subscription and check in the application where my car is. The problem is that this system has a waterproof plastic housing and the charger contacts are embedded in plastic and are quite unusual. I will have to undress and take the cables outside.

I'd like to meet Your opinion - what you think about it. Any advice?

In my opinion, too expensive and in addition too obvious, the location

And my Tractive GPS is already mounted and running in the car. In addition to purchase costs (about PLN 220) and PLN 5 for a one-time subscription for other costs, there were no. Self-assembly has many advantages because I did it more accurately and I installed it in an unusual place.

yeah, and everyone goes with a duster. It's better to do nothing. This is an alternative to several times more expensive GPS trackers sold on Allegro and installed as if by installers willing for cash.

buddy, show me the gsm jammer for 110 zlotys, gps yes but not gsm, because these cost over 1500 zlotys.

the player Chojniczanka was just caught who was surprised by the police visit because the gps gave the information about the stolen car.

I have a Locon locator in my car. Anyway, I've probably asked about it in this forum.
My opinion on this subject is simple - there are thieves who can deal with everything, and there are also those who can beat on everything.
And I bought the locator not only for this - for example, route monitoring is a very useful option. Same speed alerts.
