If you want to sell a new portable and you do not know how you can do it ,in this posts I will give some things you should take for best choose.
- Physical Size: Portable chargers come in all
shapes, dimensions, 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 battery size.
- Battery Capacity: You’ll want to determine how much
power you need and how often you’ll want to charge your power bank. If
you’re just looking for a power bank to keep your bag in case of
emergencies, a power bank under 5,000 mAh will suffice. If you want to
be able to use your power bank multiple times before having to recharge
it, aim for 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: one 1A
port and one 2.1A port.
- Charging Output: Most portable chargers will come
with either a 1A or 2.1A output port or both. These numbers denote the
maximum rate of charging in amps. So the higher the amperage, the faster
the device will charge assuming it’s compatible. A 1A output port is
suitable for most smartphones whereas older phones (such as feature
phones and flip phones) require a 0.5A port. Tablets, iPads require a
2.1A outport for optimal charging. Power banks capable of charging
laptops will likely come with a 3A port.
- Casing and Material: If you plan on using your
external battery pack outdoors, you’ll want to choose one made of
durable materials like aluminum or silicone.
