Hot on the heels of Wildcharge’s induction pad, Energizer is partnering with XPAL Power to expand its Energi to Go line of portable battery packs.

These newly branded chargers run the gamut from an iPhone 3G or #G S battery sleeve to a couple of solar chargers to a larger lithium ion charger that can power up to three devices simultaneously even a laptop. Many of the battery packs are available already under the XPAL brand but the ones with the new packages will be available very soon in stores.

Kensington unveiled a couple of new battery pack/charger combos on Monday for use with Apple’s iPhone and iPods. They didn’t waste any time thinking up snappy names in this case however as the two new products simply go by “Battery Pack and Charger” and “Mini Battery Pack and Charger”. Both work with the iPhone and any current iPod models (except the 3rd generation iPod).

The larger of the two retails for $69.99 and measures not a lot smaller than the iPhone itself at 4.0″L X 0.37″H X 2.2″W, but promises to extend the life of the iPhone for up to 6 hours of talk time, 100 hours of music or 21 hours of video. It charges through a USB connection and can connect to the iPhone or an iPod through the dock port, powering and charging it simultaneously. It also sports a cool looking little LED battery meter.
