Used this to power an hdmi splitter - making it wireless - to power an on board monitor and CUBE. Can't complain.

I depend on this battery, with it's doubled unit, to get me through a day of surveying buildings with my laptop. The laptop battery can't support the power draining, graphic Autocad software and also keep a bright screen needed for continuously changing light conditions. The only negative is I get about 1.5 - 2 hours of power, before needing to switch packs and recharge. This is the technology, and this is my power needs. I am satisfied.

I purchased the Tekkeon 3450 to replace a lead-acid battery that I had previously used to power a field monitor. As an amateur filmmaker, the budget is always a concern and I have to admit that I was hesitant to throw down the bucks for this unit - the cheap, clunky lead-acid batteries had always worked well enough before. This was money well-spent, however, and in addition to being much lighter and more convenient than a lead-acid brick, the versatility of this unit has provided ample justification for the spend. It has already come in handy as back-up power for my camera, my laptop and even for recharging my cell phone and I've only had it for a short time now. I'm considering buying another just to have on hand for field work - there's always something that needs power and this unit does the job well.

I have used this battery with my phone, ipod, laptop, and a couple other users as well.
I have recommeded it to a number of co-workers.
The only complaint I would have is that the USB cable should be more rugged as the wires are freying after using it about 6 times.

Good battery life with laptop. Not 12-14 hours but more like 6 hours with two batteries. Light weight and good looking package. Would buy again.

Ran this battery New Years Eve powering a Tascam DR-07 for 5 hours, then, on accident, left the battery on for 24 hours and still hadn't died. Still had two bars on it. This is a workhorse.

This battery can be charged with 12 - 20 some volts and outputs many voltages for various devices. It can be used as a solar panel regulator as well. Very easy to use, too.

Used with my Audio Recording field package of Lunatec V3 mic pre-amp and Korg MR-1000 DSD recorder, both in DSD mode or 196 kHz mode, while the MP3450 may be a bit pricier than other battery packs it has all the feature & remaining charge indicators that a professional needs when the gig is the priority (and not price). An extremely well made and thought out power source with voltage selection for many other uses (video cam, computer etc.)with the ability to double them up for more amps. Will become my one standard power supply for all of my present and future needs. They could use a dual unit belt pack option and a two unit package deal for the MP3450's, and not just the 'add on' battery as often we are using 12 volt and 6 volt in the field. With the option of also allowing a double power 6 or 12 volt pack when needed. I'll be getting more of the MP3450's.

I have needed and dreamt about a battery such as this for years ... to the point that I gerryrigged my own. So, now I'm very excited that someone has finally invented it. I am pairing it with the extended battery for use in a solar power system for film production in remote locations. I am only giving it four stars because I have yet to test it in the field on an actual job ... but the home tests are very, very encouraging.

What can choose the voltage freely is convenient. Capacity is enough, too.

I use this BATTERY for "Canon EOS 7D" mainly.

USE: NotebookOne Star is too many!I purchased two of these Tekkeon MP3450's. One from B&H, and another one from a different vendor.The charger was defective for one MP3450, and the Serial Number for that MP3450 was recalled because "The battery cell can short-circuit and overheat, posing a fire hazard to consumers".See link:[@]The other MP3450 (from B&H) was not a recalled SN,and the charger seemed good, but the MP3450 wouldnot charge up. Tekkeon RMA'ed both MP3450's, and both chargers at the same time. I had 2 new MP3450's and chargers back to me about 2.5 later. Both new chargers charge up, but do not do the "Charge Test" when connected and powering a device, instead it shifts the voltage higher, which is NOT GOOD! Don't buy these, find something else. These have too many problems.

I bought this to recharge my iPhone 3GS while on extended cycle touring trips. On the first full charge of the myPower, I was able to recharge a dead iPhone 6 times and the myPower was only drained to 40%! This was just what I wanted and more.

Unfortunately, the second time I took the myPower out on a trip, it failed after it got to 80% capacity. The charge capacity now goes from 100% to 80% to zero%.

I have sent it back for an exchange. I hope the QC of the next unit is better because this is the perfect product for my needs, on paper.

I am suprized at how much power there is in this unit. I use it on my video camera rig and I have yet to run out of power during my long shoots.

5 Stars!

This battery is good for any use you might need. I use this for a battery pack for my Ikan V-8000HDMI monitor. It works like a champ. I can get about 2 hours of life from on charge. It takes about 3-4 hours to charge.

I use this gadget for supplementary laptop power during a long class. Even though the laptop is rated 19.5v, the battery works great at the max level of 19v. Tekkeon customer service was very helpful figuring this out.

Be sure you see the charging light when you re-charge the Tekkeon battery!

I shoot an HVX200 video camera to an FS-100 external storage drive. The FS-100's battery lasts about 45min and I strap this onto it and it goes forever.

That said, I also have a Canon HF-10 video camera that records to an internal flash drive. Just after I got the camera, I hooked this up to it. Put it on the correct power level setting, and apparently fried the camera. It no longer functioned. Since it was a new camera, it was returnable, but I'm not going to try and power a flash drive based device with this power pack again.

Otherwise great, and holds a charge between shoots for a LONG time.

•How you use the product
it's simple to use and it help me very much! just open, connect, choose voltage ..and here we go..

•Things that are great about it
that is light, good design...
it works even with very very bad battary of my laptop...

•Things that aren't so great about it
- I don't like that I can NOT see capacity of tis device and time left before switch off... it's very sad to see you laptop (with broken battary of laptop)..
- if you using only energy from this device you will not see in "windows 7" how much power left....

but generally, i like it.
