Which specifications to consider in a powerbank vergliech?

Generally the powerbanks, in the market come with different features, and specifications. Depending upon the usage, a user can decide which specification he should focus on to get the best power bank.

  • Capacity- capacity of the power bank is the most important criterion and which should be stressed upon in a powerbank vergleich. Capacity of a power bank, is the power which it can supply or transfer to a connected device. The capacity of power banks are measured in terms of mAh. For instance, the battery of a iphone 7 plus is of 2900 mAh, which means that it possesses the power of supplying 2900 mAh in one hour. But the capacity of a laptop powerbank needs to be higher since laptops have high mAh batteries like the Lenovo Yoga Book, have 8500 mAh batteries and they require powerbanks of minimum 16000 and 6000 mAh for proper charging atleast twice from the scratch.
  • Charging current- the next important specification is the charging current in power banks when it comes to making comparisons. Go for the power bank which has the charging current of at least 1 ampere. Charging current is measured in terms of Ampere (A) and this determines how fast will a power bank charge a device.

The reason being, Sony being an established brand sells its products at high costs as compared to MI which is a new Chinese brand in the market.

So these were some of the major considerations which one must observe while selecting or buying a powerbank. Capacity of the power bank is the major parameter followed by charging currents, interfaces and brand value of the product.
