How to charge an electric screwdriver: step by step, with battery care tips
Quick answer: To charge an electric screwdriver, plug the cable into the tool or sit the tool in its charging dock, or slide a removable battery onto its charger, and leave it until the light shows it is full. For most home models this takes one to three hours from flat. Use the charger that came with the tool, watch for a red or orange light while it is charging and a green light when it is full, then unplug it and store it cool and dry.
Learning how to charge an electric screwdriver properly makes a real difference to how long the tool lasts. A battery charged the right way holds its charge for longer and is less likely to fail in the middle of a job. A battery charged badly, or left flat for months, can lose capacity much sooner than it should.
This guide explains how to charge an electric screwdriver safely, how long charging usually takes, what the lights mean, and how to look after the battery between jobs. It covers USB charging, charging docks, and removable batteries, and it is written for home use, DIY, furniture assembly, and light repair work.

What charging looks like on most models
Most modern electric screwdrivers use a rechargeable lithium-ion battery. Some have the battery built into the handle, so you plug a cable straight into the tool. Others have a removable battery pack that you take out and put on a charger. A few older models still use nickel-cadmium batteries, but lithium-ion is now the most common type for home models.
The charging setup usually falls into one of these groups: USB charging, where a USB-C or micro-USB cable plugs into the tool; a charging dock, where the tool sits in a cradle connected to the mains; a separate charger for a removable battery; or a built-in charger with a mains cable. Check the maker’s instructions for your own model before you charge it for the first time, because the plug shape, charging time, and light meanings can vary. If charging matters when you choose a model, our guide on the best electric screwdriver explains what to look for in a battery and charger.
How to charge an electric screwdriver step by step
1. Check the tool and the cable
Look at the tool, the cable, and the charger first. The charging port should be clean and dry, with no dust or damage, and the cable should not be frayed or bent sharply at the plug. If the cable or port is damaged, do not use it. Use the cable and charger that came with the tool, or a replacement the maker says is suitable. A charger with the wrong voltage can damage the battery, even if the plug fits.
2. Turn the tool off
Make sure the tool is switched off before you charge it. On most models this means the forward and reverse switch is in the middle or off position, and the trigger is not pressed. Remove the bit if it is still in the holder, and store it in its case while the tool charges.
3. Connect the charger
Plug the cable into the tool or the charging dock first, then plug the charger into the wall socket. For a removable battery, slide the battery onto the charger until it clicks, then plug the charger in. Make sure the connection is firm. A loose plug can make the charging light flicker, and the battery may charge slowly or not at all. If you are using USB charging, use a wall adapter that can supply enough power. A very weak phone charger may work, but it can take much longer than the maker’s stated charging time.
4. Watch the charging light
Most tools have a light that shows the charging state. The exact colours vary by model, but the pattern is often similar: a red or orange light means the battery is charging, a green light means the battery is full, and a flashing light can mean the battery is very low, hot, cold, or faulty.
5. Leave it to charge fully, then unplug
Let the battery charge until the light shows it is full. For most home models this takes between one and three hours from flat, but the exact time depends on the battery size and the charger. A small mini electric screwdriver can charge in under an hour, while a larger model can take longer. Do not keep unplugging the tool to test it every few minutes, because each time you unplug it, the charging cycle restarts. When the light shows full, unplug the charger from the wall first, then unplug the cable from the tool, and store the tool with the bit removed and the switch off.
How long does charging take?
There is no single answer, because charging time depends on the battery and the charger. As a general guide, most home electric screwdrivers take one to three hours to charge from flat. The maker’s listing is the only reliable source for your own model, so check it before you buy or before you plan a job around charging time.
What the charging lights mean
Charging lights are helpful, but they are not the same on every model. Always check the maker’s guide for your own tool, and use the table below only as a general starting point.
| Light | What it usually means | What to do |
|---|---|---|
| Red or orange, steady | Battery is charging | Leave it plugged in until the light changes |
| Green, steady | Battery is full | Unplug the charger and use the tool |
| Flashing red | Battery very low, hot, cold, or faulty | Let the battery reach room temperature, then try again |
| No light | No power, loose plug, or damaged cable | Check the socket, plug, and cable |
| Flashing green | Battery is nearly full | Wait a few more minutes, then unplug |
Some models have no light at all and show charging on a small display, while others have a row of lights that fill up as the battery charges. If a light keeps flashing after the battery has cooled down and you have tried a different cable and socket, stop charging and check the maker’s troubleshooting advice. A battery that will not charge at all may need to be replaced, especially if the tool is old or the battery has been stored flat for a long time.
First charge and battery care
Many people ask whether a new electric screwdriver needs a special first charge. For most modern lithium-ion models, the answer is no. You can use the tool straight from the box if it has some charge, and charge it fully when it runs low. There is no need to drain the battery completely before the first charge, and doing so can actually shorten its life. Charge a new tool fully before the first long job, so you know how long a full charge lasts, and use the charger that came with it.
Common charging problems
If your tool will not charge, work through these checks before you assume it is broken. Many charging problems have a simple cause.
The light does not come on. Check the wall socket first, by plugging in another device, and check that the socket switch is on. Then check the cable and the plug, and try the cable that came with the tool, plus a different adapter if you have one the maker says is suitable.
The battery charges very slowly. A weak adapter is the most common cause. A laptop USB port or an old phone charger may supply much less power than the tool needs. Use the wall adapter that came with the tool, and check that the cable is fully plugged in. Cold weather can also slow charging, so let the tool warm to room temperature first.
The battery stops charging early. If the light shows full after only a few minutes, but the tool runs flat quickly, the battery may be old or damaged. Charge it fully, use it for a normal job, and see how long it lasts. If it still runs flat very quickly, the battery may need replacing. Check the maker’s advice on replacement batteries, and do not open the battery pack yourself.
The tool gets hot while charging. A little warmth is normal, but the tool should not become too hot to touch. Unplug it, let it cool down, and check that the charger is not covered and the room is not very hot. If it gets hot every time you charge it, stop using it and check the maker’s advice.
Comparison table: charging types
| Charging type | How it works | Best for | Drawbacks |
|---|---|---|---|
| USB-C charging | Cable plugs into the tool | Travel, charging from a power bank | Can be slow with a weak adapter |
| Micro-USB charging | Older USB cable plugs into the tool | Older models, spare cables are common | Slower than USB-C, plug can wear out |
| Charging dock | Tool sits in a dock on charge | Home use, tool always ready | Dock takes up space |
| Removable battery charger | Battery slides onto a separate charger | Spare batteries, long jobs | Extra charger to store |
| Built-in mains cable | Tool plugs straight into the wall | Simple setup, no separate charger | Cable is fixed, less flexible |
This table is a general guide. Individual models vary, so always check the listing for the model you are considering, and check what charger is included in the box before you buy.
Frequently asked questions
How long does it take to charge an electric screwdriver?
Most home models take one to three hours from flat, but the exact time depends on the battery size and the charger. A small mini model can charge in under an hour, while a larger model can take longer. Check the maker’s listing for your own model.
Can I leave my electric screwdriver charging overnight?
Most modern chargers stop when the battery is full, so overnight charging is not usually harmful, but it is best to unplug the tool when it is full. Do not leave it on charge for days at a time, and do not cover the charger while it charges.
Can I use a phone charger to charge an electric screwdriver?
Sometimes, but it depends on the model. A phone charger may work if the plug fits and the maker says it is suitable, but a weak phone charger can take much longer than the tool’s own charger. Use the charger that came with the tool when you can.
Why is my electric screwdriver not charging?
Check the socket, the cable, and the plug first. A loose plug, a damaged cable, or a weak adapter is a common cause. Let the battery warm to room temperature if it is very cold, and check the charging light against the maker’s guide. If it still will not charge, the battery may need replacing.
Should I charge a new electric screwdriver before first use?
For most modern lithium-ion models, you do not need a special first charge. Charge it fully before the first long job, so you know how long a full charge lasts, and use the charger that came with the tool.
How do I make the battery last longer?
Charge the tool after each job, do not store it completely flat for months, keep it cool and dry, and avoid charging in extreme heat or cold. Use it regularly, and unplug it when it is full.
Conclusion
Learning how to charge an electric screwdriver properly is a simple habit that pays off over time. Use the charger that came with the tool, watch the charging light, let the battery charge fully, and unplug it when it is done. Look after the battery between jobs by keeping it cool and dry, charging it after use, and not leaving it flat for months. The basic steps are the same for most models: check the cable, turn the tool off, connect the charger, wait for the light to show full, and unplug.
