Of course, the price is also important and can also be a purchase criterion. Using a few examples,remote control nitro boats
we can show you how big the budget for a power bank should be. For an anchor power bank with a capacity of over 20,000 mAh, you pay around 35 euros.
Such a device is about the size of a smartphone. An integrated battery, as with the Juice Pack from Mophie, costs between 50 and 100 euros. The specific price depends on the iPhone model you own. The Mophie Juice-Pack Powerstation is a version without an integrated battery and costs between 30 and 75 euros, depending on the size.
Do not expose a battery charger, battery, or power bank to high temperatures. Even from 40 degrees Celsius, the devices can be damaged.
Questions and answers about the power bank
Which manufacturers and brands are there?
The following manufacturers and brands have so far established themselves on the German market:
How long does a power bank need to charge?
The duration of a charging process depends primarily on the performance of the power bank. If a power bank only allows 0.5 A, then charging takes a correspondingly long time. Because the current flow is limited as a result. The power supply also affects the charging time. A 2A mains unit can theoretically charge at four times the speed of a 0.5A power supply.
The length of the charging cable can also affect the duration of the charging process. Since the resistance of a long cable is greater than a shorter one, you should always use a cable that is as short as possible.
How does a power bank work?
A power bank is basically just an external battery that is charged and discharged via USB ports. However, best terrain rc car
these are not individual batteries, but battery packs that can store so much energy that you can often charge tablets and smartphones several times. Important for this is the capacity, which is given in amperes or milliampere-hours.
In most cases, the built-in lithium-ion batteries are protected against deep discharge. This is prevented by the built-in electronics in the battery charger. However, if a power bank is not used for a long time, such a total discharge can still occur.
