How to choose the best portable charger

  • Physical Size : Portable chargers come in all shapes, sizes and weight. Physical size and battery capacity go hand in hand. If you are looking for an ultra portable charger, you will have to sacrifice the battery size.
  • Battery Capacity : You will want to determine how much power you need and how often you will want to charge your power bank. If you are just looking for a power bank to keep your bag in an emergency, a power bank with less than 5,000 mAh will suffice. If you want to use your power bank several times before recharging it, point to one with more than 10.00 mAh.
  • USB ports : The more ports the power bank has, the more devices you can charge. Many chargers come with 2 ports: 1A port and 2.1A port.
  • Charging Output : Most portable chargers will come with either 1A or 2.1A output port or both. These numbers indicate the maximum charge rate in amps. Therefore, the higher the amperage, the faster the device charges, assuming it is compatible. A 1A output port is suitable for most smartphones, while old phones (such as feature phones and mobile phones) require a 0.5A port. Tablets, iPads require a 2.1A outport for great charging. Power banks capable of carrying portable computers are likely to come with a 3A port.
  • Case and material : If you plan to use your outdoor outdoor battery, you want to choose one made of durable materials like aluminum or silicone.

Tips for increasing the battery life of your phone

In addition to these acimas tips that will not diminish the usefulness of your device, there are others that are a little more aggressive but that allow an even greater battery saving.

  • Switch off the device when you can not use it: in cinemas, flights, meetings or times when you can not use your device, leave it unplugged. If you get calls or messages during this time, you will know the text messages from your service provider when you switch the phone on again.
  • Turn off the phone where there is no signal: In cities in the interior where there is no signal, the phone basically transmits at higher power to try to find an antenna. If there is no signal, turn off the phone and save battery power.
  • Turn on airplane mode if you do not need to receive or make calls: often you need to work on the phone but do not need external connections. Turn on airplane mode right now and your battery will last longer.
  • Say no to multimedia features: playing, listening to music, watching movies, and various other fun items on the phone spend a lot of battery power. If you can not charge the phone, avoid draining the battery with this too!
