4000mah mobile phone powerbank

Product Detailed Description

A trade show floor drains batteries fast, and a sales team that cannot make calls loses leads. This mini power bank rides in a jacket pocket all afternoon, built for mobile phones, cameras, PDA and MP3/MP4 players and so on.

Inside sits a high quality Li-ion battery rated beyond 500 charge cycles, with built-in proprietary software that controls and regulates temperature, voltage and current. Smart capacity display, multiple protection, safe and high efficiency: overcharge, over discharge, overloading and short circuit safeguards are all covered. The clear and simple design keeps the unit mobile and portable, and the metal housing reads as a substantial gift rather than a disposable accessory.

Corporate gifting buyers favor this tier for staff recognition and event giveaways, and the shell offers room for branding in qualitative terms, turning a charging tool into a branded object. Stock it for commuters, students and travelers who need a dependable top-up between outlets.
