What's in the box? - PWRCore 20 charger and manual - 20V 4/5" brushless angle grinder and manual - PWRCore 20 20V lithium battery pack with charge indicator and manual - PWRAssist 20V USB charging adapter and manual - Assist handle - Grinding circle What I like - The charger has a 5 minute charge capability! The charger will charge a fully discharged 2.0Ah battery to around 25% capacity in 5 minutes. - Manuals in English, French and Spanish. Nowadays many things have an option with USB Power, be it a phone or flashlight, Fitbit charger, etc., or sometimes you just need a charge while you're at work.Well, the good news is that the USB charging adapter plugs into a dead battery comes and has two USB ports to charge everything you need 2.1A for each port, with a maximum total of 3.6A for both ports - The battery does not have to be full It is recommended to remove the battery pack before the charge to discharge en - it can be recharged at any time and will not develop "memory" if recharged from a partially full state. It also has a fuel gauge, which is much more accurate than my usual method (connect the battery to something and see if it works). It has indicator lights that show various states (current capacity, low battery, overheating). - auxiliary handle. I love my power tools, but sometimes they are too heavy for me to use comfortably. It's about this tool. However, with the added grip, I can securely hold the tool with both hands and get the job done. - The grinder itself works great and seems strong enough. I've used my share of anemic cordless tools and this isn't one of them. It does exactly what I want, when I want it. - Soft start is an important safety feature for me. What's not to like? - Like I said, it's a bit heavy, but the extra grip helps and I love it when my power tools have some power!
