Waterproof Magnetic Mini Box +3500mAh Battery Extender for Tracki GPS trackers for Vehicles Tracking Device for Cars Real time GPS Tracker for Vehicles. 6X Longer Battery Life, Hidden Tracking Device

This waterproof case and extended battery work great when it works. I am getting ready to order my third one now. The first one lasted longer than my second that I have only had for four months now. They stop holding a charge and only work when it is plugged in and that defeats the purpose. Good thing they are priced reasonable or I would have to move on.Update.. They contacted me regarding the issue and are helping to resolve the problem. Excellent customer service for sure!

I loved how accurate this device is. Very useful and did exactly what needed it to do. Very easy to set up.

Battery life dropped from 100% to 70% first week. Down to 20% by end of 2nd week. From there it took 5 weeks to drop to 5%. Was still working good down to 3% when I recovered it. This was on locate only setting. Some days I would locate it 20 times. Some days only 4 or 5 times.

Works great. The tracking is very accurate. Customer service is very helpful and polite.

This is what you would expect from a normal battery with the tracker but it’s six times the capacity. It will last a couple weeks with ten minute intervals and about three days with one minute updates. Six months on battery saver. The case is light weight and very strong. Waterproof too. The magnet is very strong. Even with a protective rust coating, this thing stays on through a ton of rough bumps and shakes. It is bigger than you would imagine it to be. The thing I don’t like is that th e tracker itself starts becoming unreliable and sometimes unresponsive and less accurate when it gets below 20% battery left. I mean sometimes it will go 45 minutes without an update.That’s the only problem I have with this. Otherwise you will want to get this so you don’t have to charge your tracker every other day or two. Should be good for at least a week with desired realistic settings. You don’t need minute updates 24/7.

Works as described!

This little box is strong as a gorilla. It attaches to metal, and trust and believe, you better put some blackarm into it, when you try and pull it apart. But that's what you want, because your car will hit bumps; dips; etc. The box seals nicely, holding your tracker in place. This box is EVERYTHING they said it was and is. I thank you royally for such a reliable product. Keep em coming.

Updated 2024... They have wonderful customer support. Very responsive and professional. I can't say how GREAT it is to have a company that is easy to get ahold of and actually takes the time to help you. Service is ABOVE and BEYOND!!!A representative called me to discuss my perceived issues with certain aspects of the hardware. We talked about my experiences and I offered to send the failed parts back but they said pictures would be good enough for review. The rep said the pictures would be forwarded for review by engineers for evaluation. They will be sending me replacements for the broken parts again at their insistence. I had bought these for a specific purpose and now that was over I considered it pointless to pursue this but the company wanted me to be able to use their product as intended and I ecstatic.You can buy Tracki with the confidence that the company will stand behind the product and go the extra mile to ensure you are satisfied.I will be testing the replacements to see how they stand up and i will let you know.--Original Review--I ordered two of these for the two Tracki devices I bought and after a month of use I am very disappointed in the quality of the mechanism for both attaching the Tracki to the extended battery as well as the mechanism to keep the weather proof cases closed. I bought these as insurance for tracking my luggage while traveling, while I knew this was a bit extreme I was lured by the repeated claims of quality and such. After very light use one (of two) of the clasps that keeps clam shell case closed broke off with very little effort. Both of the mechanism used to secure the Tracki to the extended battery broke off, again with very little effort. This was not after years of wear and tear, this was after very light use of a few months just using to track luggage while traveling.I did not contact the company because given their claims of quality and how this is an affordable option to more expensive options and my experience leads me to believe this is a basic design flaw. If those pieces can be broken so easily with light use I can't imagine they would stand up to the wear and tear of use in a fleet setting.Because the piece that secures the Tracki to the extended battery has broken on both they are pretty much useless. Fortunately I only signed up for 6 month cellular plan and luckily my luggage made it back without relying on these devices.

The waterproof case looks great and the magnet is strong. Now I need to find the perfect place to attach it. The large battery is also good if you want to hind the tracker and not have to charge the original one as much. If you are not in the US make sure you get the right customer service number for your area. The customer service rep that called me after I had a problem and helped me to set up my tracker the way I wanted it to be was very helpful and knowledgeable about the product they sell. It is what I think one of the best tracker for the price. Real time and accurate tracking for what you need.
