Batteries - Standard type
External batteries and power banks provide essential portable power for mobile phones, tablets, laptops and other electronic devices. At Tech Shop, we supply a comprehensive range of power solutions designed to keep professionals connected wherever they work. Our range includes compact pocket-sized units for smartphones, high-capacity models for laptops and tablets and multi-port chargers for business users managing several devices at once.
Choosing the Right Power Bank - When selecting an external battery or power bank, start by considering capacity, measured in milliamp-hours (mAh). Smaller devices such as phones and wireless earphones can be efficiently charged using compact 5,000 to 10,000 mAh models, while laptops and tablets benefit from high-capacity options ranging from 20,000 to 30,000 mAh or more.
Also, check the power output and charging standard. Power Delivery (PD) and Quick Charge (QC) technologies enable faster charging when paired with compatible devices. Look for units with multiple USB-A and USB-C ports to charge several devices simultaneously, and check that the output wattage matches your device’s requirements.
Build quality and safety certifications are also important. Choose power banks featuring overcharge, short-circuit and temperature protection. For business travel or field work, opt for rugged or airline-approved models for maximum reliability and compliance. Many of our products include LED charge indicators, integrated cables and smart charging features to optimise efficiency.
Tech Shop provides dependable, high-performance portable power solutions. Whether used for business continuity, travel or field service, our external batteries deliver reliable performance when mains power is unavailable.
