Pros

  • โ€ขCraftsmanship is good, suggesting durability.
  • โ€ขWorks as advertised and holds charge well over time.
  • โ€ขCharges phones as quickly as a manufacturer's wall charger.
  • โ€ขImpressive performance, providing a strong charge despite its size.
  • โ€ขReliable, with multiple units purchased last year still functioning well.

  • โ€ขCapable of charging a phone while simultaneously recharging the power bank.

Cons

  • โ€ขAdvertised as 'Slim' but is thicker and considerably larger than expected, difficult to carry.
  • โ€ขTakes over 4 hours and up to 20 hours to fully charge.
  • โ€ขReal capacity is slightly lower than advertised; misleading battery indicators.
  • โ€ขTyp port is for input only; lacks a battery percentage indicator.
  • โ€ขDoes not support fast charging; slower compared to highend models.
  • โ€ขSome units failed to hold a charge after brief use, leading to dissatisfaction.

Bottom Line

The Pocket Juice 20,000mAh Slim Pro offers decent performance for basic charging needs with good durability and reliability over time. However, its bulkiness, long charging time, and the absence of fast charging capabilities make it less ideal for users with modern power demands or those seeking a truly portable power bank. If the manufacturer resolved the charging issues, it could considerably enhance user satisfaction.
