The Quadra Pro-Tech Charge Backpack is a comprehensive carry solution engineered for professionals and mobile workers who demand advanced security features, extensive device compatibility, and seamless technology integration in a single, sophisticated package. With a 25-litre capacity, this backpack accommodates substantial work equipment, personal essentials, and multiple devices whilst maintaining a professional aesthetic suitable for corporate environments. The external access padded laptop compartment supports devices up to 17 inches, enabling quick retrieval without unpacking the main compartment—ideal for frequent device transitions during business travel. Security is prioritised through multiple protective mechanisms. Lockable zip pullers prevent unauthorised access, whilst an internal zip valuables pocket and discrete zip pocket within the ergonomic back panel provide concealed storage for sensitive items. A key clip secures essential accessories, and the tear-out label enables identification. Device protection and connectivity are comprehensively addressed. A dedicated padded iPad or tablet compartment safeguards mobile devices, whilst an integrated USB charging port and power bank pocket enable on-the-move device charging—power bank not included. An elasticated cable organiser maintains charging cable management and prevents tangling. Ergonomic design features padded adjustable shoulder straps and an adjustable chest strap that distributes weight evenly and enhances stability during extended wear. The wheelie bag strap enables attachment to luggage trolleys for seamless multi-bag transport. A large main zip compartment and front organiser section facilitate systematic organisation of documents and accessories. The Quadra Pro-Tech Charge Backpack represents intelligent design for security-conscious professionals demanding comprehensive functionality and reliable performance.
