Customers are saying

Customers frequently mention the long battery life and portability of the Ultimate Lithium 20,000 mAh power bank as key advantages. The LCD display and affordable price are also frequently praised features. However, some customers find the device to be somewhat large and heavy. Despite this, many feel the build quality and overall value justify these aspects.

    It’s slow to make a full charge but it last a long time. Super heavy to carry around. Got on sale but regular price is high but the economy is bad. Over all I would buy it again but at sale price not regular

    Is a little bit bulky but definitely worth the price. Provides 2+ full charges before needing to be recharged. Love the screen shows you the battery percentage too. Very convenient.

    For the price and all of the cool features it is the best bang for your buck for a charger in a similar category. I enjoy the multiple charges across all of my devices this gives me.
