Defective '5,000,000mAh' power bank
It arrived dead, but in a highly dangerous state and could have burst into flames at any moment.
If you're in the business of repairing PCs, smartphones, or tablets, then you need the tools to help you get the job done in a fast, efficient, and safe way. Updated with reader suggestions July 2017.
For the past few years I've been using flashlights that need throw-away cells such as the CR123A, which are good but wasteful. Recently I moved up to the Nitecore TIP 2017 which features a built-in lithium ion battery that can be recharged using a USB charger and a micro-USB cable and I have to admit that it works very well.
With the press of a button the Nitecore TIP can switch from a 240 lumen monster that has a 30-minute battery life, to a 1 lumen firefly that can last for 46 hours. The flashlight has a 1 year standby capacity which means it's great for storing in a toolbox.
