Works great, durable and battery last most of the day if not using brightest setting. If you need it for light on night shift then buy two to alternate and last a hole shift. Review: Garbage - What a rip off! I got this today and it's a waste of money. This seller should be sued for selling junk. Doesn't even work. No charging to input or output charging. Damn waste of money and time. ## Features - POWERS KLEIN TOOLS' COOLING FAN and small USB-C devices, headlamps, phones and more - EASILY ATTACHES TO KLEIN HARD HATS and safety helmets with accessory mounts - BATTERY CAPACITY is 3200 mAh up to 10W of total power - 2 USB-C INPUT/OUTPUT PORTS simultaneously power or charge 2 USB devices - RUGGED DESIGN with 6.6-Foot drop protection and IP54 rating ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09H3MYQ95 | | Battery Cell Composition | Lithium Ion | | Battery Cell Type | Lithium Ion | | Battery Weight | 109 Grams | | Box Contents | Rechargeable Lithium-ion Portable Battery | | Brand | KLEIN TOOLS | | Brand Name | KLEIN TOOLS | | Customer Reviews | 4.1 out of 5 stars 281 Reviews | | Global Trade Identification Number | 00092644290251 | | Item Dimensions | 8.3 x 4.3 x 5.3 Centimeters | | Item Type Name | Klein Tools 29025 | | Item Weight Unit of Measure | 68 g | | Item Width | 1.7 Inches | | Model Name | 29025 | | Model Number | 29025 | | Net Quantity | 1.0 Count | | Number of Batteries | 1 Lithium Ion batteries required.
