Ammo Can Power Supply

Portable Ammo Can Power Supply

Intro/Purpose

This project was developed out of our own desires. Hunter and I, being fond of needing portable power for such things as projects, camping, and other outdoor related activities where power isn't readily accessible, decided to build a Power Supply Unit for ourselves. With lots of experience in electricity and a lot of design processing, we came up with the cheapest and simplest Portable Power Supply. Not only is it easy, but it's rugged and powerful.

Parts List

12v 9.5Ah Sealed Lead Acid Battery (Free-$70)

We got our battery for free from a company surplus. They usually are about $50 but you can find low-quality ones from about $25

DC Ammeter ($30)

DROK's Digital 0-90V 100A DC Multimeter/Voltmeter/Ammeter Battery Monitor with LCD Screen is perfect to measure the battery's power level and current flow. Utilizing its hall sensor, you can read the current flow between the battery and the charger/inverter. The Device then calculates charge. It also reads the voltage.

300W Power Inverter ($30)

We went with BESTEK's 300W Car Power Inverter from Amazon. It is relatively cheap for the power output and its dimensions make a perfect fit for the build.

Ammo Can ($15)

We got our ammo can at our local military surplus store, but you can buy them online also.

Putting it together

Construction

All of the parts were roughly the same width so they were all able to fit on one side of the can. They were held in place with industrial double sided foam tape and then a wall of thin steel divided them from the rest of the can which is used as storage.
