Dakota Lithium 12V 3A Lifepo4 Battery Charger

Great Unit, I suggest changing the battery to Dakota Lithium 12V 10Ah. Then the Camera works for a minimum of 10 hours. B&H Thank you very much for the quick shipment !!!!!!!!!

The Watson charger works with any brand battery and the included 12v charger is a big plus. The ability to check on the condition of the battery, even without the charger being plugged in allows those with multiple batteries to avoid grabbing a dead (or near dead) battery into the camera. The quality and build of the charger is phonemail and the ability to charge cell phone or other device via USB is huge.

I tried charging my Olympus Battery using AC, and it was a snap. The Charger has a wall plug, an Auto 12V charger and a European Adapter Plug. It's a great product with a fair price.

I'm using this to power my Sony A7s with a USB charger battery that outputs 9V and 12V along with the regular 5V for USB plugs. It works great and allows me to run the camera for hours on a battery that costs as much as one camera battery.

This lithium battery is very reliable.

A+!!! I LOVE IT B&H!! 3

The Watson NP-BX1 Lithium-Ion Battery Pack and Charger Kit is perfect as a second backup battery. The charger has an easy to see charge indicator light !

It's a batery charger and it seems to work as designed. Nice to get a 12v adaptor with it.

I have a LiFePO4 100Ah battery that I use for some portable operations in the field. If I happen to have AC power then I can plug it in to this unit and turn it into a 12.6 VDC power supply. If I need to I can use it to recharge my battery. TRYING TO USE A BATTERY CHARGER TO POWER YOUR ELECTRONICS CAN EASILY KILL YOUR ELECTRONICS. Most electronics do not like voltage over 15 v and many chargers will start out at 16-18v and will fry your electronics so this device has a specific power supply mode at a steady 12.6V. Perfect.

One of the Q&A’s says the Bescor BLS50AC dummy battery adapter kit is not compatible with the Olympus E-PL9.  I asked Bescor ( answers@bescor.com ) why the kit is compatible with the Olympus OM-D E-M5/M10, but not the Olympus Pen E PL9, since all three use the same Olympus BLS-50 battery.   The response was: “It will work. Your camera just needs to be added to our list.” The Bescor is 8V 3A. The Olympus battery is 7.2V 1175 mAh (1.175A).  I did some online research to see if a device built for 7.2V could operate at 8V.  One person describing himself as an engineer posted that 7.4V Lithium batteries actually span a 6V to 8.4v voltage range depending on state of charge of the battery.  Another “senior electrical engineer” said that because all devices are designed with some voltage tolerance value, a 7.4 volt device means 7.4 volt +/- 1 to 1.5 volts.  Still other posts indicated that you can use a 3A power adapter on a 1.5A device.  By logical extension, I figured (I don’t actually know) that since the PL9 uses a 7.2 volt battery, it is probably designed to also work at 8 volts, and is also okay running at 3A. Based on the response from Bescor and the Internet voltage and amperage responses, I decided to purchase the Bescor and use it with my PL9.  I haven’t seen any sign of overheating or other problems with this setup so far, but will update this review if that changes. I did not deduct points for the need to leave the battery compartment open because I knew that would be the case when I bought it.
