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.
