Anker PowerCore Portable Charger

Anker PowerCore 10000 is a portable battery that fits in my back pocket and holds enough charge to refill my phone about 2.5 times. Reason I trust Anker over the dozens of other power bank brands is that the company has been making charging accessories since 2011 and the quality control across everything I've bought from them has been consistent. Weighing about 6 ounces and charging through USB-C, the unit shows remaining capacity through 4 LED dots on the side at a glance without needing to press a button. I carry it every day because the anxiety of watching my phone hit 15% between classes is genuinely distracting. Knowing I've a full backup charge in my bag removes that stress completely. Output is 18 watts, fast enough to give my phone 50% in about 30 minutes, and the input charges the bank itself fully in about 4 hours. Campus outlets are unreliable, half the ones in the lecture hall are dead, and the power bank solves a real infrastructure problem for $26. Matte black finish does not show fingerprints and the rounded edges sit comfortably in a pocket without the sharp corners that cheaper power banks have. I bought one for my sister after she complained about her phone dying during shifts, and she uses it daily too. The brand does not market aggressively, I found Anker through Reddit recommendations and the consistent praise from people who test dozens of chargers. That word-of-mouth credibility carries more weight with me than advertising. The 10000mAh capacity hits a useful middle ground, big enough for a full day of heavy use, small enough that carrying it is not a burden.
