WISSBLUE 18650 Charger, Universal 26650 Battery Charger with LCD Screen Can Display Capacity, Adjustable Charging Speed, Suitable for Li-Ion Battery and 1.2v Ni-Mh/Ni-Cd AA AAA Battery
Quick take
This 4-slot universal charger is built for both 3.7V Li-ion cells (including 18650 and other compatible sizes up to 26650) and 1.2V Ni-MH/Ni-Cd AA/AAA-type batteries. The LCD display shows battery and charging details, and you can choose a charge current (0.5A, 1A, 2A) based on how fast you want to charge. The main practical caveat is that loading batteries can feel a bit fiddly, and a few buyers mention cable fit can be awkward depending on the unit.
Pros and cons
Pros
- Universal compatibility for 3.7V Li-ion cells and 1.2V Ni-MH/Ni-Cd AA/AAA batteries, with automatic type recognition.
- LCD screen provides detailed charging info, including battery voltage, charge progress, charging time, and charged capacity.
- Adjustable charging speed with three current settings (0.5A, 1A, 2A) plus a discharge function to help reduce battery stress.
- Charges up to four batteries at once with independent port display info (1 through 4).
Cons
- Batteries may be a little tricky to seat in the spring contacts, especially if you prefer quick swaps.
- Some units may have a less convenient USB port alignment, making cable insertion harder than expected.
What buyers think
Buyer-review evidence for this charger is limited in breadth, but recurring themes do show up around day-to-day usability. Reviews generally describe it as easy to use for 18650 Li-ion batteries, with correct identification and helpful on-screen information during charging. A common positive angle is that it can charge four cells at a time while still providing lots of LCD detail. Where buyers run into friction, it is usually mechanical, such as the spring-loaded battery contacts feeling tight or requiring more fiddling to get cells in place, and occasional commentary about how convenient the charging port is for plugging in a cable. Overall, the feedback supports the idea that it is a practical multi-bay charger if you want display-driven control and adjustable current.
Key features that matter for 18650 and AA/AAA owners
Universal compatibility with auto-recognition
This charger is designed to work with two common battery categories: 3.7V Li-ion cells and 1.2V Ni-MH/Ni-Cd AA/AAA-type batteries. It’s intended to automatically recognize the battery type and charge independently per port, which can reduce the guesswork when you have mixed battery inventory. The physical length support is broad (about 29mm to 75mm), which is helpful when you are charging not only 18650s but also other compatible Li-ion sizes within that length range.
An LCD that shows more than “charging or not”
The LCD is a major part of the value proposition. It can switch between ports and provides data such as battery voltage, charge progress percentage, charging time, charging capacity, and the current charging speed setting. For buyers who want visibility into what is happening (rather than relying on LEDs only), this can make it easier to manage your charging routine and keep an eye on whether a cell is progressing normally.
Adjustable charging speed (0.5A, 1A, 2A)
The charger includes selectable current settings, labeled as 0.5A, 1A, and 2A. That gives you control over how quickly you top off cells versus how slowly you might prefer to charge when you are being more cautious. Reviews that mention avoiding excessive heat or setting a level to keep batteries from getting too hot align with this feature being a real-world decision tool, not just a spec.
Discharge function and built-in protections
There is a discharge function intended to reduce battery damage risk, and the charger also includes smart circuit protection for scenarios like short circuit, over heat, over voltage, and over discharge. While no charger can eliminate risk entirely, these protections are the kind that matter for everyday safety when you plug in and walk away.
Charging performance and what the time estimates mean
The product includes example charge times for common capacities and chemistries (for example, AA Eneloop-style 2500mAh around 1.5 hours, and several 18650 lithium ion examples around 1.5 to 2 hours). Use these as directional planning numbers, since real results can vary with your cell’s actual capacity, starting charge level, and which current mode (0.5A, 1A, 2A) you choose.
Port layout, convenience, and portability
The 4-slot design supports charging multiple batteries at the same time, and the LCD can display information for each selected port (1 through 4). It’s also marketed as portable and compact, which is useful if you want a single charger for home and travel, especially when you are dealing with both rechargeable AA/AAA and Li-ion cells.
Who should buy this charger?
- You want one charger that can handle both 18650-style Li-ion cells and 1.2V Ni-MH/Ni-Cd AA/AAA batteries.
- You prefer a charger with an LCD readout for voltage, progress, and charge information, instead of LEDs only.
- You like having adjustable charging current so you can choose slower charging when you want more control.
- You often charge more than one cell at once and want a 4-slot layout.
Who should avoid it?
- You need the absolute easiest, quickest battery loading mechanism. Some buyers mention the spring contact area can be a bit fiddly.
- You are sensitive to cable plug ergonomics and want the smoothest USB-C or USB cable insertion experience without any alignment quirks.
- You are charging only a single battery type (for example, only 18650s) and would rather spend less on a simpler single-chemistry charger.
Verdict
The WISSBLUE universal LCD 4-slot charger is a strong fit for mixed-battery households and for anyone who wants visibility and control, with adjustable current and detailed on-screen charging data. If your priority is accurate, screen-based charging information for both Li-ion 18650-class cells and AA/AAA NiMH or NiCd batteries, it offers a lot of capability in one device. Just be prepared for slightly more deliberate battery seating and the occasional inconvenience with cable fit depending on the unit.
