Unbeatable Deals on Power Banks and Portable Chargers
At Wowcher UK, you can access special offers on power banks, external battery packs, and portable chargers from leading brands. Our deals are designed to deliver top-tier capacity and fast charging at a fraction of the usual price, so you can stay connected wherever you go.
From compact 5000–10000 mAh models ideal for daily use to high-capacity 20000–30000 mAh units that can recharge a phone multiple times, we’ve got options to suit every lifestyle and budget. Look for features like USB-C input/output, dual USB-A ports, wireless charging, and built-in cables for convenience.
What to Consider When Choosing a Power Bank?
Capacity matters. If you only need to top up a phone once a day, a 5,000 to 10,000 mAh power bank may be enough. For longer trips or power users, 20,000 mAh and above reduces the need to hunt for a mains outlet. Remember that higher capacity also means more weight and size.
Power output and charging speed are crucial. Look for PD (Power Delivery) with USB-C, Quick Charge, or PPS technologies that multiply charging speed for smartphones, tablets, and even laptops. A 18W–100W output range covers most devices, while 60W PD can charge laptops in a reasonable time.
Ports and cables matter. A model with multiple ports allows you to charge several devices at once. Some units include built-in cables or wireless charging pads, reducing clutter. Consider whether you prefer USB-C only or a mix of USB-C and USB-A for compatibility with older devices.
Size, weight, and form factor influence portability. Slim, pocket-friendly designs are great for daily carry, while rugged or metal cases offer durability for travel or outdoor use. Some power banks include protective features like overcharge, over-discharge, short-circuit, and temperature protection.
What Are the Most Popular Types of Power Banks?
Ultra-slim power banks fit easily in pockets or purses, ideal for budget-friendly daily charging. High-capacity power banks, think 20,000 mAh and above, are designed for longer days away from outlets and for recharging tablets or laptops alongside phones.
USB-C PD power banks accelerate charging using USB-C ports, suitable for latest smartphones, MacBooks, and other USB-C devices. Wireless charging power banks, with Qi compatibility, let you drop your compatible device on the surface and start charging without cables. Some models combine built-in cables, wireless charging, and multiple outputs for ultimate convenience.
Rugged and travel-friendly options provide better protection against drops, heat, and rough handling while maintaining performance on the road or in the air.
How to Use a Power Bank Safely?
Always use the charger and cable specified by the manufacturer. Damaged cables or adapters can lead to overheating or fires. Avoid leaving power banks in hot cars or direct sunlight for extended periods, as heat can degrade battery cells and shorten lifespan.
Do not rely on a power bank as your sole energy source for high-draw devices like laptops unless the model is explicitly rated for it. For daily charging of phones and wearables, a PD-enabled USB-C port or a wireless charging pad provides the most reliable and safe experience.
When charging, ensure the power bank is not stacked with metal objects and is kept on a non-flammable surface. After use, store in a cool, dry place away from heat sources and moisture to preserve battery health.
How to Maintain and Prolong Power Bank Battery Life?
Calibrate the battery occasionally by letting it discharge to about 5–10% and recharging to 100%. This helps maintain accurate capacity readings over time. To preserve longevity, avoid complete discharges on a regular basis and aim to store the power bank around 40–60% charge for extended periods.
Keep the device and its ports clean from dust and debris. Use a soft, dry cloth to wipe surfaces and check for loose connections that could cause arcing or poor contact. If you won’t be using the power bank for weeks, store it in a cool, dry place and recharge every few months to maintain battery health.
For added safety and convenience, consider models with built-in protections, such as over-charge, over-discharge, short-circuit, and temperature safeguards, and opt for certified brand options with quality-tested cells. This reduces risk while ensuring long-term reliability.
What Is the Best Way to Choose a Power Bank for Travel?
Travel-friendly power banks should be compact, lightweight, and capable of fast charging for smartphones, tablets, and even laptops. Look for airline-compliant models with 100Wh or less to avoid extra screening at security; this is crucial for frequent flyers and business travelers. If you need to top up on long flights, choose a power bank with high capacity but still within airline limits and a solid build for rugged handling.
Consider models with multiple outputs so you can charge several devices during layovers and keep essential gadgets powered before boarding. Wireless charging can simplify setup and reduce cable clutter in tight spaces. Finally, check the warranty terms and whether Wowcher offers extended protection for electronics.
From sleek to rugged, fast-charging to wireless, the right power bank can transform how you stay connected on the go. Check out Wowcher UK’s ongoing deals on power banks and portable chargers to save more while keeping devices ready for every moment.
How Do You Choose the Right Capacity for a Power Bank?
Start with your typical daily load. If you mostly top up a smartphone, a 5,000 to 10,000 mAh model is often enough. For a device ecosystem with tablets or compact laptops, look at 20,000–30,000 mAh or higher. Remember that capacity is not only about how many devices you can charge; it also affects the size and weight you’ll carry during travel or daily commutes.
Balance usage with the charging speed you need. A smaller capacity with fast PD output can recharge a phone quickly, while a large capacity with moderate output might be better for multi-device setups. Choose a model that matches your most-used devices and travel patterns.
Can a Power Bank Charge a Laptop?
Some power banks are rated to charge laptops, especially those with USB-C PD outputs over 45W. If you rely on a laptop, look for a high-wattage PD power bank (60W, 60–100W range or higher) and confirm compatibility with your laptop’s USB-C charging standard. Always check the manufacturer’s guidance and carry a suitable USB-C to USB-C charging cable. For travel or daily use, a dedicated laptop power bank may offer safer, more reliable performance.
If you don’t need full laptop charging on the go, consider a combination setup: a high-capacity PD power bank for phone and tablet plus a lightweight wall adapter for the laptop when you have access to power outlets.
Is Wireless Charging Safe for Power Banks and Devices?
Wireless charging power banks use Qi standards that are widely tested and generally safe for devices designed to support wireless charging. The key is to use certified products and avoid placing metallic objects or magnetic accessories between the pad and device, which can cause heat buildup or charging interference. As with any battery tech, avoid overheating by using the charger in a ventilated area and away from direct sunlight.
For extended trips, combine wireless charging with traditional cables for flexibility. Rotate between a wireless pad on a desk, a PD USB-C cable for fast charging, and a spare battery bank so you’re never left without power.
