Oga feflo pls can you help me build a rectifier or psu of 14v to 15v?

UPS and Power Inverter:

UPS - UPS or the uninterruptible power supply makes use of an internal inverter to convert DC power to AC. Then it stores power in its built-in battery.

Power Inverter – The inverter is generally connected to an exterior DC source to maintain continuous AC current flow. In this case, a standalone battery or batteries are used for storing energy.

Basic difference:

In UPS, the switchover to backup power is prompt, while in an inverter there is a little delay. This break is acceptable on household appliances like fans, lights, and fridge, but it is not suitable for sensitive equipment like computers and printers. Such delays can cause system crash and data loss.
It uses the main supply line for sending power to various appliances at homes or offices. Unlike the UPS, it is not directly plugged to the appliances.
Technical variance:
UPS – In UPS, the AC from the main power is transformed to DC. This DC is continuously charging the battery. The DC output from the battery is fed to a sine waveform inverter that converts it into AC and supplies it to the equipment.
The energy is regularly drawn from battery, and hence there no gap during the outage on the main. The battery stops getting charged now, but the UPS continues its power supply till the battery gets completely discharged.

Inverter – The main power AC is supplied to the inverter, and it is transformed into DC simultaneously, which keeps charging the battery continuously. There is a sensor and relay structure that always monitors the ON or OFF status of the main.
As soon as there is a power failure, the relay actuator activates the inverter switch. Every other action is similar to the UPS, but because of the sensor and relay process, there is a delay while activating the switch.
Circuitry dissimilarity
Circuits used in making UPS are very expensive than the ones used in an inverter. This is the reason why UPS systems are expensive.
UPS generally comprises:
Rectifier or charger – Rectifier transforms the AC current from the main to DC current, to charge the battery
Inverter – It converts the DC voltage from the battery to AC current, to the electrical equipment
Controller – It regulates the functions of both the rectifier and the inverter.
Inverter comprises:
Inverter – Firstly it converts AC of the main to DC for battery charging. Then it changes the DC power from the battery to AC current, and that flows to the electronic equipment
Controller – It manages the inverter functions

I have a 55inch tv, two ceiling fans and a standing fan, a ps4 and charging of phone and laptop .. what recommended inverter installation can I go for that can serve me for up to 7 to 10hrs power? .. budget friendly

LORDKing001:
Pure sine wave inverter plus battery

LORDKing001:
How much last sir

LORDKing001:
I need a pure sine Wave inverter with battery

LORDKing001:
Expensive
Need something for a project

LORDKing001:
Does it include battery?

luvlyoracle:
inverter alone is awmuch

Do you sell adjustable charger that can be adjusted say from 0v to like 60v?
