Portable extrenal battery charger

Amazon is not bad but i'll recommend wagawoo hear from my friends, for this those are famous for all kind of battery chargers like Industrial chargers, marine chargers, lithium packs and many more.

I tried this one posted on Amazon.

TimeTec 2 x 1800mAh Li-ion Batteries For Motorola Atrix 4G, ME860, MB860; Fits BH6X + Free Bonus TimeTec Multi-purpose USB Travel Charger

It's a combo pack, two 1800mAh battery with an external charger. Charging is fast. So it called travel charger. I just spent 20 something, so far so good since Nov. 2012. Share with you.

The first thing you need to address when selecting your external electric electric battery power is to select a charger that delivers at smallest the identical or greater yield in volts. The storage capability is significant because it determines not only how much of a ascribe the power pack can shop, but how much it power it can send out before it furthermore desires recharging.

I've been using this:

Amazon.com: Anker® Astro3 10000mAh Multi-voltage (USB output: 5V, 2A; DC output: 9V / 12V, 2A) External Battery Pack ( Dual USB Output plus DC Output ) for Samsung Tablets, Netbook, Digital Cameras, DV Recorders, PS Vita, Nexus 7, NDS, NDSL, GoPro; i

Works out great.

It will charge the D4 at least 5 times before it needs recharging itself
