The Anker PowerCore Essential 20000 PD offers the large capacity of a laptop power bank but limits output to save costs, making it ideal for charging handheld devices for long periods.

The Anker Zolo is very good value for money, considering its power, capacity, handy features, and build quality, but the lack of ports on a bank this size feels like a missed opportunity.
