The battery holds a charge for a long time.
She went on to inform me, however, that I would have to wait for a RMA email before I could send it back.

Ever been frustrated when you bought a toy for the kids or maybe one for yourself, opened it and then learned you needed things that weren't in the box, like perhaps batteries?

Well, here's a twist: a battery that comes without the accessories you need to make it work with your devices.

Adding insult to injury is the fact that Energizer's offer of the "free" tips you need to make the device operative is more or less false. They claim the adapter tips are free and that all you pay is shipping and handling. Guess what folks: the "shipping and handling" brings the cost of the "free" tips of what other power supply vendors charge. There's nothing "free" about the offer. Of the 15 supplied tips, only 4 were for devices I owned. I had to order 3 others. What is interesting is that each of the tips carried its own "shipping and handling charge". Adds up quick that way. In my opinion, the offer of "free tips" is utterly bogus.

To their credit, they do have tips for Dell and HP computers which some of their competitors don't. Of course, no tips for the Dell and HP computers I have access to were included.

The battery itself seems to work. I have no means of accurately measuring its output and how long it will power various devices, so I have to go with the manufacturer's estimates. It is a cleanly designed unit, well constructed, relatively compact and weighs just over a pound. It will add some weight to your travel kit, but if you are stuck somewhere and need power, this is a good alternative.

Energizer claims you can charge three devices at once. This is another dubious claim. You can charge three devices at one time IF a) one of them uses 5vDC, b) another uses between 9 - 12vDC and c) the third needs 16 - 20vDC.

I was trying to decide whether to buy a second battery for my laptop but then decided to buy this instead. Keep in mind that when you eventually upgrade your laptop, all the extra batteries probably wont work with the new machine. There are a couple of things I like about this unit.

1. Once you charge it up, it seems to HOLD the charge forever. I charged it up when I received it in November....and then went on a trip in January but forgot to put it on charge right before my trip....no problem it had a full charge already. I've heard from others that it stays charged up for months at a time. If you're like me, you cant always predict exactly when you are going to need the extra power.

2. The unit is sleek, not too heavy, and very compact. I only travel with the cables required to connect to my laptop.

3. It seems to power my laptop forever. My original laptop battery lasts maybe 1.5 to 2 hours.....and with this power pack, I can take that to 4+ hours.

4. Great for international flights in economy....you can tuck this unit into the seat-back pocket and tap away on your computer.

5. There is a USB charging port that you can use for pretty much any type of mobile device out there.

6. I can take this from laptop to laptop and it will stay with me long after I upgrade my laptop.

I truly cant think of a downside except the high price. Everyone seems to be whining about paying $4 shipping for a new tip. If you cant afford to spend $4 on a tip, you shouldnt be buying a $100+ battery for your laptop. The purpose of the $4 charge is to ensure that the people dont abuse the "Free" tips service. It is designed to serve as a 'hurdle' that requires people to ask themselves if they really need the tip before placing an order. I doubt that $4 even covers the administrative/fulfillment costs for Energizer.

I bought one of these on January 10 on [...] for [...]...a real steal considering the regular price.
Apparently it has been offered there before at [..]. Who knows if it will come up again.

I bought it to carry in my laptop bag to recharge my blackberry or extend the run time of my laptop in case I find myself away from AC for too long...like on a cross-country flight.

Although it came with a lot of different tips, the mini-usb and micro-usb are the ones I will probably use the most.
It came with a tip that fits my Dell Latitude E6500, and appears to power the system just fine, but Dell, in it's infinite wisdom, has some technology that refuses to charge the battery if you use a non-Dell power supply. I did check online with the Tip Finder, and discovered that the site recommended that I get the AB14 tip (the one supplied with the unit is AB08). I went ahead and ordered one in case that would make the laptop a bit happier with the XPal.
My sense is though, that to get the most run time out of the laptop, I should run the laptop battery down completely, then plug the XPal in and set the laptop to NOT charge the battery so that all of the energy from the XPal will go to running the laptop rather than the much-less-efficient task of trying to recharge the laptop battery (a function key combination can set it to not charge...on my Latitude it's Fn+F3)

Some reviewers have complained that the 'free tips for life' carry a shipping and handling charge of $10.
While that may have been true in the past, after I registered the unit for warranty, then went to the tip finder, at checkout I was only charged $3.95, which seems pretty reasonable to me.
