These tools can get very pricey — if you don''t need the extra bar length, battery life, and power, then there''s no need to drop the extra cash on a super high-performance model. With all these advantages comes a few drawbacks. The 20V battery life is quite a bit shorter than most higher-voltage models, like the Ego Power+ CS1800.
Customer ServiceIf the power bank battery lasts for the same number of hours as listed in the capacity, then it is the actual capacity. In reality, this capacity is less due to power losses.

Customer ServiceAs you might remember from our article on Ohm''s law, the power P of an electrical device is equal to voltage V multiplied by current I:. P = V × I. As energy E is power P multiplied by time T, all we have to do to find the energy stored in a battery is to multiply both sides of the equation by time:. E = V × I × T. Hopefully, you remember that amp hours are a

Batteries are made up of a group of cells where a cell is the smallest individual electrochemical unit. These cells are connected in series, in parallel, or in a combination of both in order to obtain the required voltage and capacity. A typical battery rating consists of the following terminologies: 1. Nominal Voltage
Battery nominal voltage depends on the nominal voltage of the cell and the connection of the cells. The nominal voltage of the cell depends on the combination of the active chemicals used in the cell. For a lithium-based cell, it’s usually slightly over 3V. For the battery in the above figure, the nominal voltage is 3.7V. 2. Nominal Capacity
Charge Voltage (V) This is the voltage that the battery is charged to when charged to full capacity. Charging schemes generally consist of a constant current charging until the battery voltage reaches the charge voltage, then constant voltage charging, allowing the charge current to taper until it is very small.
The first important parameters are the voltage and capacity ratings of the battery. Every battery comes with a certain voltage and capacity rating. As briefly discussed earlier, there are cells inside each battery that form the voltage level, and that battery rated voltage is the nominal voltage at which the battery is supposed to operate.
The problem here is that ampere-hours do not take into account the voltage of the battery and so two batteries of the same physical size may have a different number of cells, and therefore a different ampere-hour rating, even though the energy stored may be the exact same quantity in mega joules.
