Lenmar R2G802U AC/DC Charger

No USB Output Power From Batteries

By SMS  Sep 7, 2011

Pros: Charge from USB or AC or Cigarette Lighter Outlet

Cons: No USB output from batteries, can't close unit with batteries inside, poor documentation

When the batteries are inserted into the charger the cover cannot be closed, so it's a pain to carry with the batteries inside. The USB output for charging phones, etc., is not powered by the NiMH batteries, though this would have been a simple featu...re to include, since 4 NiMH batteries provide 4.8V to 5V. The packaging does not state that the USB port is only operational when the unit is plugged in, with the batteries fully charged. If you're looking for a combination AA/AAA charger and power bank then this is not the product you want, look at products from Tenergy like the Zap CP4-AA Power Bank, which is less expensive and more functional, though it lacks the alarm clock and temperature functions. The manual is poorly written, referring to "charging plates" that are not related to AA/AAA chargers, only to Lenmar's chargers that can charge proprietary Li-Ion packs. The packaging states that the batteries are charged and ready to use (like Sanyo eneloop batteries), but this was not the case. The manual does state that the batteries must be charged prior to use. The temperature feature on the alarm clock really ends up telling you the temperature of the batteries that are being charged, not the surrounding air temperature. A poorly designed, poorly documented product. I returned it. Read more Less
