Review

This latest model from Nitecore is made a little more budget friendly and less time consuming. It is advertised as twice fast charging and literally gets the job done within minutes. Like other models of Nitecore chargers, this one is also highly compatible. Included equipment helps to fit in AA and D type batteries as well. 

After insertion of the batteries, this charger instantly detects the batteries and sets the voltage and current accordingly. When charging is done, it notifies the user with its lights. Its auto shut off mechanism only works after 20 hours of plug in to prevent overheating.

It would be nice if it has the auto shut off function for each batteries. But its fast charging capability gives the relief from charging multiple batteries for long time. With its 12v plug, you can charge your batteries using a car battery when the power is out. For the affordable price, it is a good universal charger.

Things We Liked

  • Fast charging;
  • Comes with equipment to charge AA and D batteries;
  • High compatibility;
  • Can charge different batteries with ease. 

Things We Didn’t Like

  • In the package: EBL Battery Charger, User Manual and an AC adapter.

Review

18650 batteries are used in lots of devices we use daily so as the 18650 chargers. But a considerable number of vapers look for chargers which ar smaller in size so that those can be carried easily. EBL charger is made considering the requirements of vapers. It is not just only in good quality and shape, but also made smaller in size, so that you can put this in your pocket ant carry all day.

The best thing about this charger is, it is ETL certified, hence its quality is beyond questionable.  Besides, it can be used both AC and DC current. Over charging and overheating is less likely happen with this charger due to its auto shut off feature. 

This charger does all the things it was advertised with. But for professionals, I would recommend to look for a charger with four slots and higher compatibility. This one is more fair for travelers and users on budget.

Things We Liked

  • Portable;
  • Budget friendly price;
  • Auto shut off when charged full.

Things We Didn’t Like

  • 2 battery slots only.

4. MiBOXER 18650 Smart Battery Charger

  • Work with Li-ion(4.20V / 4.35V) / IMR / INR / ICR / LiFePO4(3.60V) :10340, 10350, 10440, 10500, 12340, 12500, 12650, 13450, 13500, 13650,14350, 14430, 14500, 14650, 16500, 16340 (RCR123), 16650, 17350, 17500,17650, 17670, 18350, 18490, 18500,18650, 18700, 20700, 21700, 22500,22650, 25500, 26500, 26650,Ni-MH/Ni-Cd(1.48V): A, AA, AAA, AAAA and C,;
  • In the package: MiBOXER Battery Charger, User Manual and USB Wire.

Review

The point of using a 18650 charger with multiple slots is to charge a mix of batteries of different requirements. Most of the charger in market automatically detects the battery type (volt, capacity etc) and supply current accordingly. But batteries with lower capacity needs manual setting of lower current supply. In MiBoxer 8 slot charger, you can manually select the amperage of low capacity battery and ensure charging without damaging the battery. 

Another amazing function is repairing lithium-ion batteries; if you have batteries that shows ‘0 voltage’ can be regained its power simply by placing it in this charger. Attached LCD display shows charging state but percentage, which is more accurate than showing LED lights or bars. The charger has several safety protection for the batteries and charger itself. It ensures stress free charging for years.

Included USB wire lets you use the charger almost anywhere and everywhere. This wire gives this charger portability despite of its 8 slots that cannot be found in other 4 slot chargers in market. For an 8 slot charger, the price is quite reasonable, it is much less than paying for 2 chargers with 4 slots.

Things We Liked

  • 8 slots;
  • Easy to operate;
  • Manual setting for low capacity batteries;
  • Comes with USB wire;
  • High quality charger. 

Things We Didn’t Like

  • No cons.

  • Compatible with:  Li-ion(4.20V / 4.35V) / IMR / INR / ICR / LiFePO4(3.60V) :10340, 10350, 10440, 10500, 12340, 12500, 12650, 13450, 13500, 13650,14350, 14430, 14500, 14650, 16500, 16340 (RCR123), 16650, 17350, 17500,17650, 17670, 18350, 18490, 18500,18650, 18700, 20700, 21700, 22500,22650, 25500, 26500, 26650,Ni-MH/Ni-Cd(1.48V): A, AA, AAA, AAAA, C and SC.;
  • In the package: MiBOXER Battery Charger, User Manual and USB Wire.

Review

Everyone doesn’t need 8 slots charger on daily basis. So, Miboxer launched this 4 slot 18650 charger with similar advantages as their previously reviewed 8 slots charger. If you are already amazed with the features of 8 slots Miboxer charger but needs a smaller one, then this review is just for you. 

Like the previous one, this charger also lets you select the current for low capacity battery. It has automatic setting as well that detects what the battery needs and charges accordingly. Apart from the USB port in the packaging, this charger is also compatible with DC12V car chargers. Now you can charge your batteries on the go.

This 4 slot charger costs less than half of the 8 slot one. For a quality device that comes with a long warranty, this price is negligible.

Things We Liked

  • Compatible with  DC12V car chargers;
  • Repairs 0 voltage batteries;
  • Reasonably priced;
  • Has manual setting for low capacity battery. 

Things We Didn’t Like

  • Manual is not very helpful.

6. UltraFire Universal Battery Charger

Features

  • Slot for battery: 2;
  • Compatible with:  -3.7v Li-ion/IMR/INR/INR/ICR/LiFePO4: 10340, 10350, 10440, 10500, 12340, 12500, 12650, 13450,13500, 13650, 14350, 14430, 14500, 14650, 16500, 16340, 16650, 17350, 17500, 17650, 17670, 18350, 18490, 18500,IMR 18650,18700, 20700, 21700, 22500, 22650, 25500, 26500, 26650, -1.2V Ni-MH/ Ni-Cd: AA, AAA, AAAA and C;
  • In the package: UltraFire Battery Charger, User Manual, US Plug Power Supply Cord and Car Charger.

Review

It is a 2 slot charger from UltraFire. We have previously reviewed another 2 slot charger from EBL. the major difference between two is, this one comes with a car adapter and the EBL one came with a AC adapter. People consider chargers with car adapter to keep those in their car always; so that they can always stay prepared even if left home without charging those life saving batteries. 

This charger is a smart one, like all the chargers we have reviewed in this list. Other than identifying the batteries automatically, it shows the battery type along with other information (charging state, capacity, resistance etc). It is a universal charger as the name claims; so, you don’t have to worry about compatibility when you are heading for traveling around.

For some, its two slots are perfect to put the charger in their pocket where ever they go. Others may find it insufficient to meet their all demands. In my opinion, a two slot charger is best for traveling or charging necessary items on the go. 4 or six slots are best for home and workplaces.

Things We Liked

  • Durably made;
  • Universal battery;
  • Overcharge protected. 

Things We Didn’t Like

  • 2 slots only.


7. Surophy 18650 Universal Intelligent Charger

Features

  • Slot for battery: 4;
  • Compatible with:  32650, 26650, 26500, 25500, 22650, 22500, 21700, 20700, 18700, 18650, 18500, 18490, 18350, 17670, 17650, 17500, 17350, 16650, 16340(123A), 16500, 14650, 14500, 14430, 14350, 13650, 13500, 13450, 12650, 12500, 12340, 10500, 10440, 10350, 10340 1.2V Ni-MH/Ni-CD, 3.6V/ 3.7V Li-ion/IMR/INR/ICR and AAAA/AAA/AA/A/C/SC/D;
  • In the package: Surophy Battery Charger, User Manual and adapter.

Review

This one is the most versatile charger I reviewed in this list. Other than charging cylinder shaped rechargeable batteries, this device can work as a power bank, can discharge, refresh and test batteries. This one device can replace 4 to 5 devices from your tool box. 

With the included adapter, you can use this charger as a power bank when you are in hurry. Just make sure all the slots are busy with batteries. It ‘charges’ in a blink and ‘discharges’ partially charged batteries to lengthen the battery life. You can ‘refresh’ your used/defective batteries or ‘test’ the good ones for more assurance. All these can be done by easy changing of ‘MODE’ of the charger.

The only thing I noticed is, the plastic body is less durable compared to other chargers within this price. However, the versatility of this charger makes this one more useful than other chargers in times of emergencies.

Things We Liked

  • Versatile battery;
  • Can charge, discharge and test batteries;
  • Works as a power bank;
  • Eliminates memory effect. 

Things We Didn’t Like

  • Made with thin plastic.

8. Zanflare Universal Battery Charger with Car Adapter

Features

  • In the package: Zanflare  Battery Charger, User Manual, power adapter and car adapter.

Review

This charger is somewhat less fancy compared to other 4 slot chargers of this list. Fewer options lets you operate any device in less hassle. So, the ease of operation is the best feature of this device. Besides, with the included power and car charging adapter, this charger earns your faith that, you can charge any batteries anywhere. 

There are 3 modes of charging. Other than just charging batteries, you can identify and refresh the batteries manually with ‘FAST test’ and ‘NOR test. This charger does not have any discharge button. Other than this, it is a useful one to keep alive all your new and old batteries of varying capacities.

It offers 4 different current for each of the slots. You can choose from 300mA / 500mA / 700mA / 1000mA depending on the capacity of the batteries you want to charge. If any battery is not inserted properly, the LCD will show ‘NULL’ and when charged fully, it will show ‘FULL’. Besides, other useful info regarding to the batteries will be displayed as well. It is a handy and reliable tool for me.

Things We Liked

  • Sturdy construction;
  • Travel friendly;
  • Operates with AC/DC current;
  • Power bank functionality.

Things We Didn’t Like

  • Does not support LiFe PO4;
  • Refreshing battery takes longer.

9. Nitecore D4 Universal Home/Car Battery Charger

Features

  • Slot for battery: 4;
  • Compatible with:  Li-ion (26650, 22650, 18650, 17670, 18490, 17500, 18350, 16340(RCR123), 14500, 10440), Ni-MH and Ni-Cd (AA, AAA, AAAA, C) rechargeable batteries ;
  • In the package: Nitecore  Battery Charger, 4 Nitecore 18650 NL189 3400mAH rechargeable batteries with 2 ps EdisonBright AA to D type battery spacer/converters.

Review

First of all, beware of the price of this unit, before heading to the review section. This charger comes with high capacity Nitecore batteries, hence the cost is crazy high. If you don’t need those batteries and don’t want to break the bank, then this review is not for you. 

Nitecore is known to be the leading brand for high quality batteries and chargers. The quality and capacity is undoubtedly satisfactory. So, this package is designed with quality charger and set of quality batteries with adapter. There is no car adapter to power adapter, so, don’t expect this charger to show miracles for you in odd situations. 

The Nitecore batteries are of high capacity and holds charge for eternity. The charger is a smart universal charger, does all the job it advertised. It detects the batteries and charges all of those independently and quite quickly. If you desperately need Nitecore batteries, then this unit will save you from ordering those separately.

Things We Liked

  • Included batteries are of high capacity;
  • Compatible to low capacity batteries;
  • Charges LiFePO4 batteries as well;

Things We Didn’t Like

  • Very expensive.

10. Basen 4-Slots Intelligent Universal Battery Charger

In the package:  Basen BO4 Battery Charger, power Cord, user manual and warranty card.

Review

It is the most economic charger I have reviewed so far with satisfactory performance. Quality is not compromised here, nor the intelligent functions. To cut the cost, LCD display is not attached to this charger. With its four slots, it can only charge selected Li-ion batteries. Less compatibility is another characteristic of this charger.

The included USB port is a convenient addition, to charge batteries with almost anything within your reach. You can use this charger with AC current without any problem; to use it with DC current, you will need an adapter of DC 5V/2A capacity.

This device comes with all the protection functionality we always look for in Li-ion chargers. For safe and convenient charging within a economy range, this one is a wise option.

Things We Liked

  • Economic;
  • Good quality;
  • Comes with USB charger.

Things We Didn’t Like

  • Needs an adapter, not included;
  • Only for Li-ion batteries.
