Batteries : what you need to know.
All batteries are not created equal, far from it. Before you buy your laptop battery there are a few technical characteristics which it is necessary to be attentive.
The storage capacity of a laptop battery is measured in milliampere-hour, mAh. The more you have of mAh, the longer your laptop battery stores electricity.
It is good to note that, regardless of the battery, there is a loss of energy due to the conversion of pressure and heat that it produces. The external batteries on the market are generally effective in 60 % or 70 %. Only a few premium products can boast up to 90 % efficiency.
To be sure to be able to fully recharge your device, it is necessary to choose a portable battery that has more mAh than your mobile phone.
Another aspect to take into account is the debit entry, that is to say, the speed at which your laptop battery is charging. It is measured in amperes, A (sometimes referred to as “Amp” on the packaging). The more amps, the more the battery recharges quickly.
Finally, it is necessary to consider the output of the portable battery, that is to say, the speed at which the battery will recharge your mobile phone. It is measured in amperes.
The majority of smartphones are recharged with 1A (5W). However, some recent models, “quick charge”, can be recharged more quickly in the absorbent 2A (10W), for example.
So, choose a portable battery the number of amps suitable for your phone. Please note, that unfortunately, an external battery with an output port 2A does not reload, not a mobile phone 0.7 A faster, and vice versa. If your phone is “quick charge” and that he accepts a flow input of 2A, but as you recharge with an external battery with the capacity of 1A, it will reload less quickly.
Additional features : the most gadget in the most useful
The lamp torch.
Auto-on/Auto-off : the laptop battery is running and stops automatically when a device is plugged, which allows to minimize the loss of energy.
The LED or LCD screen : they display the level of the external battery.
SMART or Power IQ : recognizing the amperage of the device to recharge, the backup battery optimizes the reload time.
“Passthrough charging” or Reload direct : allows you to recharge the battery and the device (phone, tablet,..) at the same time. Taking two shots !
How to choose a laptop battery ?.
Choose a laptop battery depends on your needs and your devices. The thing is to find the balance between portability, cost, number of charge and speed of recharge.
Some people may prefer a portable battery that slips easily into a bag and offers two cartridges full of their mobile phone, others will pick up a battery most imposing that has under the hood, and allows you to charge multiple devices at the same time.
