The power bank can charge the power bank. Detailed introduction: When the user uses a power bank to charge the power bank, one of the power banks will be in a discharge state, while the other power bank will be in a charging state. If they are connected in reverse, the charging and discharging states will be reversed, and the charging state will be reversed. There will be "power loss" in the process. Although power banks can charge each other, if the cycle continues, the power that can be converted into the power bank will become less and less. , Therefore, this charging method makes no sense. It seems to be "brain-burning", but it is actually a "brainless" problem.

The operating environment of this tutorial: Windows 10 system, DELL G3 computer.

With the emergence of smart phones and lithium battery technology, power banks have emerged in order to increase the battery life of mobile phones. However, many users have begun to think about a "brain-burning" question: "Power banks can give power banks "Charging?" This article combines the charging and discharging principles of power bank to talk about whether this method is feasible.

Can a power bank charge a power bank?

Can a power bank charge a power bank?

All power banks circulating on the market generally only have two functions, namely charging and discharging. , charging refers to using other devices to charge the power bank, and discharging refers to using the power bank to charge other devices. The power bank has a built-in "charging IC system" that can automatically identify the connected device and decide whether to charge or discharge.

When a user connects two power banks together, no matter how the two power banks identify each other, charging or discharging behavior will occur. This means that the power bank can charge the power bank.

Can a power bank charge a power bank?

Charging and discharging principle of power bank

Power bank generally consists of switch, charging interface, motherboard, battery and casing. The battery is generally lithium The battery voltage is generally between "2.7~4.2V". The voltage will decrease as the power decreases. However, this voltage cannot be directly charged to other devices. It needs to be boosted to above 5V through a "boost system". Only then can you charge other digital products.

In addition, because the lithium battery core is a smart battery, it can be used for long-term and repeated charging and discharging operations when used in mobile power banks.

The effect of charging a power bank with a power bank

When a user uses a power bank to charge a power bank, one of the power banks will be in a discharged state. The other power bank will be in a charging state. If connected in reverse, the charging and discharging states will be reversed, and there will be "power loss" during the charging process. Although the power banks can charge each other, if the cycle continues, The amount of electricity that can be converted into a power bank will become less and less.

So, this charging method makes no sense. It seems to be "brain-burning", but it is actually a "brainless" problem.

Can a power bank charge a power bank?

Digression: A power bank is actually a rechargeable battery that can be used multiple times, but due to limitations in voltage, charging interface, and device interface, it needs to go through a special system and equipment to convert it into a battery with an intelligent charging system.
