Pros and cons

Pros

  • Individual charging channels offer flexibility when you have fewer than four cells to recharge.
  • The claimed charge gauge and automatic shut-off provide status information and reduce the need to monitor charging continuously.
  • Four AA batteries are claimed as part of the bundle, so it can be used with rechargeable cells straight away.

What to know before buying

Listing details to confirm

Charging times are contradictory: one listing claim says a full charge takes one hour or less, while the product description and details say four hours, with the description noting times may vary by NiMH battery. Confirm the expected charging time for the selected unit and cells. The title identifies four AA batteries as 2000 mAh, while the supplied description does not repeat that capacity. The listing also differs on whether charging can begin with one cell or only two or four. Follow the charger instructions and charge NiMH cells only. Use it in a dry location and in a vertical or floor-mount position. Do not plug it into an extension cord.

Who is it for?

A good fit for

  • People who recharge AA or AAA NiMH batteries for household devices, toys, cameras or controllers.
  • Buyers who want individual channels and charging-status indicators in a charger bundled with AA cells.

Less suited to

  • People needing to charge battery chemistries other than AA or AAA NiMH.
  • Buyers who require an unambiguous charging-time specification before purchasing.
