A quick-and-easy solution would be to use a USB power bank for 5V. This deals with all the charging and protection issues, and boosts the LiPo output. For your 3.3V projects, a linear low-dropout regulator to take 5V down to 3.3V might be the easiest solution, if not the most efficient. A DC-DC module that has good low-power efficiency would be
If the standard were 4.5V instead of 5V, probably the battery wouldn''t charge completely in the worst case (and DC-DC would be a must). If
Most if not all laptops have internal battery charge monitors and regulators and also cater for some differences in natural battery cell voltage. I would say it should be safe. If in doubt, connect a pair of 5A (or more) diodes in series with the power supply to drop a volt or two.
If you have a DAC that requires USB power (i.e. 5V, 1A) then there are several options: 1. A spare USB port on your computer; 2. A phone charger; 3. A ''power bank'' battery pack that is usually used to charge mobile phones; 4. A linear power supply; 5. A ''specialist'' switched power supply like iFi iPower 5V. There may be other options too.
A 5V power source refers to a power supply that delivers a constant voltage of 5 volts. It is widely used across various electronic devices, such as smartphones, computer peripherals, microcontrollers, and other low-power applications. the smartphone''s internal battery will receive the required charging current. 5.

You''re operating under the misconception that whatever is providing 20V/9V/5V is a charger when they actually are power supplies. The power supplies are never directly connected to the battery, instead they are providing power to the charger that then manages the charging of the battery.
First and most important, it is not safe to charge a battery with higher-than-specified current. Doing so risks damaging the battery (at best) and causing a fire or explosion (at worst). Fortunately, what you are asking about is not the charging current, but the current available from the power supply that supports the charger. The actual battery charger is inside the "small
The long answer to the question is an app note: Introduction to USB Power Delivery Applications. In short, mobile devices that use USB for battery charging "negotiate" current with the DC power supply 1 which provides +5V on USB. The mobile doesn''t simply draw the maximum current that it can to draw.

One potential risk of charging a 3.7 V Li-ion battery with a 5V charger is overcharging. Li-ion batteries have specific voltage requirements for optimal charging, usually around 4.2 volts. Using a higher voltage charger can cause the battery to charge too quickly or at an excessive voltage level, leading to overheating and potential damage.
Batteries can be charged manually with a power supply featuring user-adjustable voltage and current limiting. I stress manual because charging needs the know-how and can never be left unattended; charge termination is not automated.

They can also be used to power other devices that need a 5V supply. Before this standard, phone chargers often consisted of a current limited power supply that acted as a trickle charger, possibly in concert with a circuit in the phone that cut off when the battery reached full charge.
For example, if a charger is rated at 5V/1A, that means it has the output potential of supplying 5 voltage with 1 amp. It can not exceed that unless the charger is faulty. But if the charger is rated with an output potential of 5 voltages and 2 amps, then it doesn't mean that the charger will supply 2 amps of current.
If you charge your mobile at 5V/1A with a charger rated at 4V/1A, the battery will not get the required voltage, and hence it will not charge. If you use a 5V 1A charger with a 5V 2A output, we can infer that the voltage is pushed into the battery, and 1A from the 2A is pulled into the device, and it will charge smoothly.
First, let's start with the numbers. “Output 5V” refers to the voltage level at which the power supply operates. Voltage is the electrical pressure that determines how much power is delivered to your device. In this case, the power supply outputs a voltage of 5 volts.
Among the many types of batteries available, 5V batteries stand out for their versatility and ability to power a wide array of devices. From smartphones to emergency flashlights, these batteries are everywhere, silently supporting our digital and mobile lifestyles. But
Phone and tablet 'chargers' output 5V to emulate USB power. But things that don't connect to USB often use different voltages (my cordless phone charger puts out 9V). So the answer is:- USB and that is the only reason. Maybe because that was the original TTL supply voltage?
