Buying a battery charger? All chargers in one convenient overview

How do I choose the best battery charger?

Before choosing a battery charger, it is important to know what types of batteries you want to charge. Do you mainly use AA or AAA batteries for remotes and toys? Or do you also have 18650 batteries for your torch? At Knivesandtools, you will find chargers suitable for various battery types, including our best-selling battery type: the 18650 battery.

Note the number of rechargeable batteries at a time

If you often need to charge several batteries at once, a charger with multiple slots is handy. For example, we sell chargers where you can charge 4 batteries simultaneously and automatically adjust the charging current for each battery. This saves time and ensures that all your batteries are quickly ready for use again.

Consider additional features and security

Some chargers offer convenient extra features, such as a built-in display showing charging status or a USB output to charge your phone. Safety is also important; choose a charger with protection against overcharging and short circuiting. This way you get the most out of your battery charger and keep your batteries in top condition.

Smart battery chargers: convenient, versatile and indispensable!

At Knivesandtools, you will find smart battery chargers that do more than just charge. For example, many models have a drip mode to keep your batteries in top shape and a resuscitation function that revives even deeply discharged batteries. Safe and practical!

They automatically recognise the right charging current, so your battery is always optimally charged without risk. Do you have multiple devices? With the 'daisy-chain' option, you connect chargers together without the need for extra USB ports. Some models can function as a power bank, ideal for on the go.

From Li-ion 18650 chargers to NiMH AA battery chargers

Many of our battery chargers are universal. This means that lots of different types of batteries can be charged in the battery chargers. For example, the battery chargers can charge both Li-Ion and NiMH batteries. There is a small difference in the charging process for each type. Li-Ion has slightly more capacity and charges faster than NiMH. Over time, Li-Ion loses some of this capacity, while NiMH does not. Rechargeable batteries and a battery charger may be slightly more expensive to purchase than disposable batteries, but the investment quickly pays for itself.
