Dlypow 2-Slot 18650 Battery Charger (Micro USB, LED Status)

Quick take

This Dlypow 2-bay charger is designed for households and hobby gear that mix battery types, charging both Li-ion (including 18650/14500 and RCR123A-style sizes) and 1.2V Ni-MH/Ni-CD AA/AAA. It uses auto-adjusted charging current by battery type and shows progress per slot with LEDs, but you may need to consult the manual to interpret blinking/error indications confidently.

Pros and cons

Pros

  • Universal-style compatibility across common Li-ion and 1.2V Ni-MH/Ni-CD sizes (including 18650, 14500, and AA/AAA).
  • Auto-charging current targets up to 1000mA for Li-ion and 500mA for Ni-MH, depending on battery type/size.
  • Two separate slots with individual LED status (charging, full, and error indications).
  • Safety protection features including overcharge, short-circuit, reverse polarity, and 0V activation.

Cons

  • Two slots only, so it is slower if you need to charge many cells at once.
  • Some buyers find it helpful to learn what the blink/error behavior means for their specific batteries.

What buyers think

Reviewed productBuy on Amazon

Buyer-review evidence for this charger is generally positive, with repeated themes that it powers on correctly and reliably charges batteries to full. The overall sentiment also points to simple, straightforward day-to-day use (it “works as expected”), and buyers frequently mention satisfaction with value. There is limited evidence of confusion around the LED/blinking behavior, suggesting the primary learning curve is understanding the status indicators rather than a recurring charging failure.

What this charger is for

If your devices use a mix of rechargeable formats, this 2-bay charger is built to reduce the number of chargers you keep. It is aimed at common battery ecosystems like flashlights and small electronics that may use 18650-class Li-ion cells, plus everyday AA/AAA rechargeables. It supports multiple popular sizes, including 18650, 14500, 16340 (RCR123A), 22650, 18490, 17500, and also AA and AAA Ni-MH/Ni-CD at 1.2V.

Charging behavior and speed (what the specs tell you)

The charger is rated to deliver up to 1000mA for Li-ion charging and up to 500mA for 1.2V Ni-MH/Ni-CD charging. It also uses auto-charging current based on battery type and size, which can make it easier to operate with mixed inventories. Practically, that means you can expect faster charging for Li-ion batteries than the Ni-MH/AAA side, and the charger will be better suited for routine refills than for simultaneous bulk charging of a large battery haul (because it only has two bays).

LED status per slot, plus built-in safety protections

Reviewed productBuy on Amazon

Each bay has its own LED indicator so you can check what each battery slot is doing at a glance. The general pattern described by the product includes red for charging, green for full, and blinking for error. For safety, it includes protections for overcharge, short-circuit, reverse polarity, and 0V activation, which matters if you have batteries that have been drained for a long time.

Design, portability, and setup

At about 60g and compact enough for a desk or travel kit, the charger is positioned as a convenience item rather than a bulky workshop tool. It uses a Micro USB input, which can be a plus if you already have common cables at home or in your travel bag. With two bays, it is most convenient for small batches, top-ups, and weekend device maintenance.

Who should buy this 2-bay charger

  • You want one charger for mixed rechargeable batteries, especially 18650-class Li-ion plus AA/AAA 1.2V rechargeables.
  • You prefer simple, slot-based status feedback to reduce guesswork about whether a battery is charging or finished.
  • You need a compact charger for home, office drawers, or travel kits.

Who should skip it

Reviewed productBuy on Amazon
  • You regularly charge many cells at once, because two bays will limit throughput.
  • You need advanced charge customization (for example, a charger designed for deeper diagnostics). This is built around automatic current adjustment and basic status signaling, not extended programming.

Battery compatibility checklist (to avoid mistakes)

Before buying, confirm your batteries match what the charger targets. This charger is intended for rechargeable formats in the 18650/14500/16340-family Li-ion space and for 1.2V AA/AAA Ni-MH or Ni-CD. If you have a different chemistry or an unlisted size, double-check first. For best results, follow the manual’s guidance for inserting cells and interpreting the LED states, especially when you see blinking behavior.

Verdict

The Dlypow 2-slot 18650 battery charger is a practical, budget-friendly choice for people who want one device to cover both common Li-ion cells and everyday AA/AAA rechargeable batteries. With auto-adjusted charging current, per-slot LED status, and multiple safety protections, it fits home and travel use well. The main tradeoff is capacity, since two bays mean slower bulk charging, and you may want to review the manual briefly to understand the LED blink/error indications.
