Buying Guide for the Best Magsafe Battery Packs
Choosing a MagSafe battery pack can help you keep your phone charged on the go without fussing over cables. Since these battery packs attach magnetically to the back of compatible smartphones, they're designed for ease of use and mobility. When selecting the best MagSafe battery pack for your needs, consider factors like how much time you're away from a power outlet, the size and weight that feels right for your daily carry, and if you have extra features you’d like to have for added convenience.Capacity (mAh)The capacity of a MagSafe battery pack is measured in milliamp-hours (mAh) and tells you how much power the pack can store. This is important because the higher the capacity, the more times or the longer you can charge your phone before needing to recharge the pack itself. Battery packs usually range from about 2000mAh to over 5000mAh. A lower capacity pack is lighter and slimmer—good for short outings or those who just want a small backup. Higher capacity packs are bulkier but can charge your phone more times on a single charge, suitable for heavy phone users or people who travel a lot. Think about your daily habits: if you just need a top-up before getting home, a modest capacity will do; if you're away from power all day or on trips, go for a higher capacity.
Charging Speed (Wattage)Charging speed tells you how quickly the MagSafe battery pack transfers power to your phone, usually measured in watts (W). Faster charging means you spend less time tethered to the pack, which is especially handy when you’re on the move. MagSafe packs typically offer speeds between 5W and 15W. Lower wattage means slower charging but can generate less heat and may be gentler on phone battery over many cycles, which can matter for overnight or occasional charging. Higher wattage charges your phone more quickly—great if you often need a fast boost. Choose based on how urgently you usually need power: slow and steady for convenience, or faster speeds if you need to top up quickly.
Size and WeightMagSafe battery packs come in a range of sizes and weights. This is important because it affects how comfortable the battery feels while attached to your phone, as well as how easy it is to carry in your pocket or bag. Lighter, slimmer packs are comfortable to use for quick boosts and don’t add much bulk. Bulkier packs offer more power but can feel awkward during extended use. If you want something that’s barely noticeable or can fit into a small pocket, choose a smaller pack. If you regularly depend on your pack to last the whole day, be prepared to live with a bit more weight and size.
Magnetic StrengthThe magnetic strength determines how firmly the battery pack attaches to your phone. Stronger magnets mean the pack stays securely in place during everyday use, like walking or moving the phone around. Weak magnets might lead to accidental slips or disconnects. For regular, active use or if you carry your phone in various positions, look for a pack praised for its strong magnetic hold. For occasional or stationary use, all legitimate MagSafe packs should do the trick.
Pass-Through ChargingPass-through charging lets you charge both your phone and the battery pack at the same time when the battery is plugged in. This is valuable for convenience—just plug in before bed and wake up to both devices fully charged. Not all battery packs offer this, so if you like plugging in overnight or minimizing cable juggling, pick a pack with this feature. If you only use the pack for emergencies or quick outings, this feature may not be essential.
Additional FeaturesSome MagSafe battery packs come with extras, like indicator lights to show charge level, a built-in stand for propping up your phone, USB ports for charging other devices, or compatibility with accessories like wallets or cases. Think about your daily routine: if you prefer to travel light, these may add more convenience to your experience. If you only care about battery backup, you might skip the extras.
