Charge phone with AA batteries

Introduction

When all other options have failed, how can you charge your phone? Create your own DIY portable tiny power bank, which could be useful, especially while travelling or camping outside. Anyone can complete this hobby project by following some very basic directions. Since a phone requires 5V to charge, the mobile charger reduces the voltage of the four 1.5V AA batteries to 5V using the voltage regulator IC 7805.

How to charge phone battery without charger

If you've had a dead camera battery at the very time you needed it most? A dead cell during an emergency is even worse. Furthermore, it's not always possible to carry a charger. These suggestions might be helpful for people who enjoy to (or must) improvise.

A.How to Charge a Battery using a Battery

B.Take the electronic device's battery out. With your hands, hold it.

Use both of your hands to vigorously rub the battery to create enough heat and friction. From 30 to several minutes, keep doing this.

Note: No power is being added to your battery. Some internet commenters have claimed that massaging the battery might give it an extra charge, possibly from static energy that has accumulated. ?This interpretation is completely false.

Like all true batteries, lithium ion cells produce power as a result of chemical reactions. These reactions intensify with rising temperatures, as anticipated by the Arrhenius equation. ?By increasing the temperature of the battery, you are essentially increasing its conductivity.

Can I use battery to charge my phone

Cell phone batteries frequently fail at the most inconvenient times, when there is no nearby ac power outlet. Cell phones and other portable electronics like music players, e-book people who read, and cameras may be recharged using this adapter design, which uses three common AA batteries that are available practically everywhere.

The circuit chargers that frequently accompany mobile phones and other portable gadgets briefly charge the battery. They pause, check the voltage, and compare the temperature to a table inside the device before deciding whether to resume charging or not. This technology takes advantage of the charging regulation that the battery needs, which is carried out inside the charging device.

1.Take the device's battery out. You will require access to the battery's connection points. Know what can be done with the model you have because some cell phone models are not designed to have the battery accessed. With the right amount of pressure applied in the ideal location, the back can be removed off the majority (but not all) Android and Windows phones. With the majority of Apple goods, avoid trying this.

2.Locate some 9-volt, AA, or AAA batteries. The power in typical household batteries is identical to that used by your cell phone or camera battery, unlike the power that comes from a wall outlet (alternating current).

3.On each battery, note the positive and negative contacts. These will be marked on the AA batteries and other common batteries. The positive connector is typically the one that is closest to the edge of most cell phone batteries, while the negative connector is typically the one that is farther away from the edge (there may be three or four connectors, but the middle one or two are used for temperature regulation and other functions).

4.the voltage of the battery you need to charge and the other battery should match (AA, AAA or others with enough power to provide). Today's cellphone batteries typically require higher voltage than 3.7V DC to charge. In order to provide a charge, several AA or AAA batteries or one 9V battery will be inactive. Remember that typical household AA or AAA batteries give 1.5V apiece. So you need three AA or AAA batteries connected in series to get more than 3.7V. Your power source would be 1.5V + 1.5V + 1.5V = 4.5V if the battery in your palm is an AA or AAA model.

5.Collect two lengths of metal wire. Except for the exposed ends, these are best covered in plastic insulation.

6.Connect the wires to the batteries that will be supplying and receiving power by taping or clamping them. These wires may become warm (though most likely they will not if you are doing it properly). Additionally, the charge transfer will take a while. You shouldn't keep them in your arms the entire time.

7.When utilising AA and AAA batteries, it's a good idea to connect them "in serie" before joining them to the battery that has to be charged. The negative sides of all the tiny batteries must be wired together and connected to the negative connector .

8.The battery should eventually be charged. Although it definitely won't be fully charged, you should still be able to use the gadget you needed.

Phone charger that uses batteries 

Battery cases are useful, but they do have certain disadvantages, such as being big and heavy and occasionally having a negative impact on wireless reception. Nothing compares to a specialised portable charger or power bank that you can stow conveniently and only use when necessary. There are many options available for charging your Android handset, ranging from wired options to ones that can wirelessly charge your phone.

PowerCore Fusion Portable Charger by Anker :This Anker product is essentially a large wall charger with a 5,000-mAh battery inside. It has two regular USB charging connections so you can charge your phone and an additional device at the same time (or two phones). Additionally, a small LED indication on the side makes it possible to quickly check the charge level.

Portable Charger MyCharge Home & Go 4,000 mAh : With its integrated folding prongs, the MyCharge Home & Go Portable Charger may be charged directly from a power outlet. The 4,000-mAh variant is compact and thin and only includes one USB-out (no USB-C cable included).

5K Moshi Porto : Approximately $85 Similar to the MyCharge Unplugged, Moshi's Porto Q 5K (5,000 mAh) is an expensive portable battery that also functions as a wireless portable charger. Compared to the MyCharge Unplugged, it is swankier and more fashionable, and it charges via USB-C rather than Micro USB. For wired charging, there is a USB-out port, and two devices can be charged and recharged at once.
