Chargers for many batteries

Charging a rechargeable battery or battery pack also requires the right charger for the battery (unless the battery has a built-in charging port or is charged via the used electronics device). To find out which charger is ideal for you, you should consider the following questions:

  • What voltage (V) battery are you looking for a charger for? 
  • How many batteries do you want to charge?
  • What is the right amperage (A) for you and how fast will it charge?
  • What size of battery would you like to fit?18650? 21700? AA?

Once you have the answers to these questions, finding the right one is a piece of cake!  Arrange products by popularity, price or name, use the Filters to see only the products that are right for you.

If you decide to buy a charger, you will soon find yourself looking at the range and wondering "BUT WHAT?", as there are so many different chargers available and it is not clear which one is ideal for you. We've put together some of the most important questions that you should ask yourself to make sure you buy the charger you REALLY need:

  • Which battery do you need the charger for? What battery do we need? Or both? Because then it's worth paying attention to this, some chargers are designed for just one, others for the other, and some can charge all types of batteries, even at the same time. And if you're looking for a charger for a 1.5V battery, get one that's definitely suitable for that battery, because a standard 3.7V Li-ion charger won't work. 
    How many batteries do you want to charge? 1,2, 4, or more? You shouldn't buy a charger that holds 8 batteries if you never use more than 2.
  • Are we using protected or unprotected batteries? You can charge a protected battery with practically any quality charger, because in the worst case - if that crappy charger overcharges the battery and the battery catches fire - then only the battery is hurt, the apartment won't burn down, because the battery protection solves the problem, but why is this a dangerous game. And with unprotected batteries, it's especially risky if you're not familiar with the subject, so the combination of shoddy charger + unprotected battery + amateur user is pretty dangerous.
  • Do we want our batteries to last hundreds of charges or does it not matter? If you want a charger that is gentle on your batteries, then buy one that, for example, does not charge Li-ion batteries above 4.2 V and gradually increases the charging current. 
  •  Do we have time to sit next to the charger while it is charging, or do we want it to discharge itself when it is done? I can't stress enough, if you're not handy enough, don't buy a crappy charger because you could set the house on fire if you're not careful. Buy a charger that does the job for you, you just put the battery in and it does everything else for you. 
  • Is it important to charge very quickly, or do you have time? A 0.5 A charging current will charge the batteries sooner or later, and 2-3 A will also charge them, but the difference between the two is 5-6 hours.
  • Do we want to use it as a power bank and charge the phone, for example? A practical solution is to have a charger that can charge outwards, with the phone plugged into it, or other micro-usb gadget, so you can charge it whenever you want.
  • Do we want to monitor the charging status on an LCD display? Do we want to know how much power has been charged so far, what is the current voltage of the battery, how long has the battery been charging, at what charge rate? Or is it enough if the machine just indicates that the battery is ready or still charging? We offer both versions, so choose the one that suits you best.
  • Is a USB cable enough or do you need a wall charger or car charger? Different chargers are available in different packages, the easiest is the usb cable, which plugs into your computer and draws power from there. Or, if the lamp is one, you can get a charger that plugs directly into the wall charger.
    Want a professional charger that does everything the big ones do for half the price? Worried about your batteries heating up or shorting out?  Need a charger that can not only charge, but also drain the battery, test it and even measure internal resistance?  
  • What size battery will be in the charger? the CR2 battery is too small (15*27 mm) for most chargers, so a special charger is needed for such a battery, but the most common 21700 battery will not fit in all chargers, especially the protected 75 mm version, so it is worth checking before buying if the battery will fit.
