I have noticed that the battery could not be charged when I turned on the computer.
Stephen Lee
Also works in a pinch to charge up a cell phone on the go, or to give a laptop an extra hour or two of usage.
Amazon Customer
I received the device and found the included "tips" that I would use were to plug in only the USB port.

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.

Verified Purchase
Read most of the reviews, took the really bad ones with a grain of salt - since we all know that most reviews of anything are going to be negative, anger makes folks write while happiness makes most folks get on with their lives ;-) - and prior to paying about the same for a full new laptop battery for a notebook that I probably wont have for another year I tried the XP18000.

Very happy. Very.

Out of the box the brick was powered, the instructions said to fully charge it eight hours but I actually thought I might need it that day so I went with it and all of the included tips.

When my Fujitsu t4220 was down to 20 percent I tried the blue cord and the notebook instantly reported it was plugged in. I kept on working since it wasn't losing power anymore and in about a half hour I noticed that my laptop batteries (main and module pack) were both reporting fully charged. Kept working. A few hours later I was again down to 20ish so I plugged it in again and once again I was fully charged while contining to work. I didn't plug the XP18000 in when I got home, just left it in the bag. Next day, I used it again and it fully charged my batteries while I was working. At that point the little blue indicator was down to one bar so I charged it.

That is my main mobile machine so I was happy... out of the box. But then because of the negatives (and comments form people who admit that they don't even own one) about the box having no tips for real users I played around with the included tips and for my common-use units here were the results:

Fujitsu T42xx series convertable (as noted above) 19w, works with the included blue cable, no added tip required.

Acer Ferrari 4000 linux box, same as above.
