Specs

  • Voltage: 12V.
  • Size: 19.7x 96 x 1.43 centimetres
  • Battery type: Lithium Polymer.
  • Charge time: Between 7 and 16 hours.

Customer Reviews

According to one disappointed user, this is a 21,000mAh power bank and not a 26,800mAh as claimed. Further disgruntlement is that the Charmast customer services had not replied to the complaint after two weeks. But, on the bright side, another happy customer says this is one of the slimmest chargers he has ever seen! Its 3 input and 4 output USB ports also allowed good speed charging of two Apple devices simultaneously.

Pros

  • Being waterproof makes it ideal for outdoor activities such as hiking and camping.
  • Built-in compass which must be placed flat on the floor as tilting will affect its direction.

  • Compatible with MP3 Players, Smartphones, PC, Tablets and Cameras.

Customer Reviews

Customers disliked the fact that the product does not charge beyond half of its advertised capacity. Further concerns are that 30% battery power drains out within 10-15 minutes. Other complaints centred around its longevity, with users claiming that the charger “died” within 1-4 weeks from date of purchase. The device works well when plugged into the mains and charged from an electrical network – just as the manufacturer recommends. While some users are happy with the product, the overall consensus is that it is not sufficiently robust and a waste of money.

Frequently Asked Questions and Answers

  • Are power banks bad for your phone?

    Power banks can damage a phone battery. That is why it is essential to buy high-quality power banks with a built-in safety system to protect devices from overcharging and overheating.
  • Can power banks charge laptops?

    Not all power banks can charge laptops because they need to have a higher voltage output. The voltage output must range from 16V to 20V. While the charger can also be used to juice other devices, laptops devour loads of energy so you will probably only be able to replenish the laptop battery once or twice before recharging the device.
  • Do power banks come charged?

    Most power banks are pre-charged but won’t have enough power to charge your phone entirely. They are usually charged up to about 75%. Most power banks have LED lights that indicate charge level.
  • Do power banks work with all phones?

    Check the specifications of your existing charger before buying a power bank. As a rule-of-thumb, an iPhone and most Android smartphones need at least one amp (five watts),
  • Which power banks support fast charging?

    Several different brands offer fast charging support in today’s highly competitive market. Our fast-charging picks are the ROMOSS 20000mAh, Anker 13000mAh and 2000mAh, the Belkin 10000mAh and 15000mAh and, finally, the Kogan 26800mAh.
