![]() ![]() With the right mix of power bank, cable and device, it is possible to deliver power to laptops, although this can be a little hit and miss, because the device and the power bank have to effectively negotiate the power delivery level that will be safely used. What you want to look for there is a power bank that offers Power Delivery, or PD, as a standard. It’s a little more complex if you want a power bank to keep power flowing to a laptop or other high wattage device. If a power bank can deliver higher wattage to your connected device you may find it charges faster, but it’s not guaranteed. Some power banks do support standards such as Qualcomm’s Quick Charge if your phone supports that standard, meaning you can juice up your phone much faster, but there are alternative standards such as Oppo’s VOOC, which aren’t usually called out in power bank specifications. ![]() However, that’s not the full story if you want faster charging, and especially if you need a power bank to back up your laptop’s power supply. ![]() There’s a certain universality when it comes to charging smartphones from a power bank, because you can pretty much plug any phone into any power bank and get the electrons flowing. When charging up the power bank, you should get a compatible cable whether your device uses micro USB, USB-C or Lightning, but usually not an actual plug charger. While USB-A is the most common (because most charging cables end with that rectangular type plug anyway), there are some power banks that offer up either USB-C or Apple’s Lightning connection points, although the latter is fairly rare in an output sense. It’s worth matching up connector types here too. Most high-capacity power banks feature multiple outputs, which is handy if you’re planning on powering up more than just your smartphone, or if you just want to be nice to your friends and family when they’re caught in a bind. How many devices do you need to keep juiced up?

The realities of power transmission are inherently lossy, and the actual transmission rate of the power will also have an effect on how much charge it’s able to put out on a given device. Not quite, although you should see more than three recharges if the power bank is relatively new and fully charged for sure. Here’s everything you should consider before buying a portable phone charger, along with a few of our top picks. That way you’ll always be prepared for anything. So, if you want to ensure your phone’s battery stays in the green, grab yourself a portable power bank. Of course, the latter can always be fixed by a data blocker. Especially, if you consider how much of your personal information is stored within your smartphone. The second issue is juice jacking, which poses as a serious security risk to your device. Plus, sometimes there’s no power point available either. While you could always resign yourself to bringing your wall charger along, or use a public phone charger, you risk two potential consequences.įirst of all, nobody wants to squat in a corner or linger in a café while trying to recharge a dead battery. That’s why a power bank can become your best friend.įor some of us, it feels virtually impossible to go anywhere without a phone, so we’re constantly using it and draining its battery. While the convenience of a smartphone is great, frequently having a flat battery is not. BTW - prices are accurate and items in stock at the time of posting.
