If you have a smartphone, you probably need a portable charger to keep it charged up. But finding the right charger can be difficult – there are so many to choose from, and they all have different features.
One important factor is capacity: If you need to recharge your phone or tablet often, you’ll want something in the 10,000mAh range. For more casual users, a smaller brick in the 5,000mAh range might suffice.
The Pocket Juice Extreme 10000 from Tzumi packs a lot of power into a compact package, making it easy to take with you on the go. The small footprint means that it fits easily into your pocket, purse, or backpack, and the LED lights at the top show you its charge level. It also has two high-speed USB ports, a Micro-USB slot to recharge it, and protection from overheating, overcharging, and over-discharging.
Its performance in our 15-minute and 1-hour charging tests put it near the top of our rankings, though we wish it had a second output port like the Anker PowerCore Slim. But its overall high score, excellent battery life and size, and durable construction make this a great choice for your next power bank. It can refuel an iPhone 12 almost three times on a full charge, and it will recharge most smartphones faster than most of the competition. And it has a one-year limited manufacturer warranty to give you peace of mind if it ever fails.
