Battery Packs: Your essential buying guide
Choose based on the device you want to power. Controller battery packs are usually shaped to fit specific controllers, while portable power banks are better for handheld consoles and accessories that charge by USB. Always check compatibility with your console, controller model and charging cable before buying.
Rechargeable controller battery packs can be a practical choice if you play regularly, as they reduce the need to keep replacing disposable batteries. Look at charging method, claimed capacity, whether a cable or dock is included, and whether you want one pack or a multi-pack for extra controllers.
Battery capacity is often shown in mAh. A higher mAh rating can indicate longer potential use, but real performance depends on the device, settings, age of the battery and how you play. Compare capacity alongside compatibility, size, charging time and convenience rather than using mAh alone.
Some USB portable battery packs can charge a range of devices, but fitted controller battery packs are usually made for particular controller designs. Check the product details for supported platforms, connector type and whether the pack physically fits your controller or handheld console.
Useful features include USB-C charging, clear charge indicators, pass-through charging where supported, compact sizing, overcharge protection and bundled cables or covers. For shared setups, a twin pack or spare pack can make it easier to swap batteries between players.
The right battery pack depends on what you play on, how long your sessions last and whether you need a fitted controller pack or a more flexible portable charger. Use ShopSmarty to compare options across the gaming battery pack category and narrow your choice by compatibility, capacity and charging style.
Compatibility is the most important check. A pack designed for one controller shape or battery bay may not fit another, even within the same console family.
For handheld consoles and USB-powered accessories, look closely at the connector type, output rating and whether the pack is intended for charging while in use. If you are buying for multiple devices, a universal portable battery pack may be more flexible than a fitted controller pack.
Capacity can help you estimate how suitable a pack is for longer play sessions, but it should be viewed with charging time and convenience. A higher-capacity pack may last longer, while a smaller pack may be lighter and easier to keep attached to a controller.
If you often forget to charge between sessions, consider spare packs or sets that let you keep one battery ready while another is in use.
Some battery packs charge directly by cable, while others work with a dock, stand or dedicated charging station. Cable charging is simple and portable, whereas dock-based charging can suit a tidy desk or TV unit.
If you already have gaming accessories arranged around your console, matching your battery pack with your existing charging setup can make everyday use easier.
For controller battery packs, the shape and weight can affect how the controller feels in your hands. Slim, flush-fitting packs are generally better for keeping the original controller feel, while larger packs may prioritise longer use.
For portable chargers used with handheld consoles, consider where the pack will sit during play and whether the cable length will be comfortable.
Charge indicators, secure battery covers, USB-C support and built-in protection features can make a battery pack easier to live with. Multi-packs are useful for households with several controllers or players.
Before comparing deals, check what is included in the box, such as cables, covers or adaptors, so you can compare like for like.
