The Belj B-L-Y00 is a small, budget 5000mAh power bank for topping up a phone, earbuds or a smartwatch during a long day, a load-shedding evening or a commute. It is a slim, pocketable black slab measuring 93 x 63 x 13.5 mm, built around a lithium-polymer cell. Esquire lists it with a USB-C input at 5V/2.1A for recharging the bank itself and a 5V/2.1A USB output for charging your devices, which is standard-speed charging rather than fast charging, so it suits keeping a phone alive rather than charging tablets or laptops. A 5000mAh bank will typically give a modern smartphone roughly one partial-to-full charge depending on the handset's battery size. Esquire's listing also mentions a battery-level display and a built-in LED light, though the mailer photo shows a plain unit, so check the exact feature set on delivery. Comes in retail packaging with a 1-year limited warranty.
