The Energizer charger has insufficient juice to charge the Nuvi. Nuvis charges via USB rated voltage of 5 volts while the energizer runs on double AA which makes it total of 3 volts only.

Err... I think there's a voltage step up circuit inside... The output voltage is 5V DC...

IMHO, it will barely charge a Nuvi, especially the 4.3" size ones as they are power guzzlers. Just look at the Garmin provided Mains / Car charger specs ... 1A max rating !! Even the built in Lithium Battery barely last 3 hours so don't expect much from 2 tiny AA batteries. You may have to carry a box of batteries and that is heavy to lug.

For periods of no access to mains power to recharge, I would carry a hand-crank charger such as shown in pic

All non-Garmin 3rd party chargers will lead Nuvi to "Data Mode". Only with Garmin Chargers will the unit boot up in normal mode.

There is a work around to use your Nuvi while its charging:

1. Switch to Diagnostic Mode : press on Battery Icon ( press must be long ~4 - 6 secs )
2. While in Diagnostic Mode, connect your USB
3. Press Exit button in Diagnostic Mode screen
4. Use your Nuvi while its charging

Bro Moey, not so X la ... about US$20 which is about Sin$30 and RM 72
Here is the link : http://www.dealextreme.com/details.dx/sku.11128

Been buying stuff from them for some time with free shipping to Sin. I am sure you can find it in SLS if you look hard enough...

Changi airport is good for reference base price :thumbsdown: ... but not for buying unless emergency .... :-'
Do you use PayPal to pay for the item?

Don't want to use PayPal, is there any Other way to pay for the items at DealExtreme ?

Thanks.
