This is the original tristar chip tester. I’ve been using this thing for a year or two now and I can tell you that this thing is essential for micro soldering. It saves so much time testing to see if your iphone or ipad has a charging port or charging chip problem.
The tristar tester is especially great for ipads because this thing allows you to test whether there is a charging port fault or charging chip fault without disassembling the ipad first. The time save is well worth the money. We label this tool as an essential tool for micro soldering work.
The device comes with a rechargeable micro usb port.
