With the Quantum Instruments QB1+ 1 Battery is an affordable, reliable power source with 6V power for most shoe-mounted flash units that use 4 or 5 AA batteries. Clip the QB1+ on your belt or carry it with the included strap, and get 26 oz (737 g) of concentrated power, typically enough for 250 full power manual, and more than 1000 automatic flashes. This power source has colored LED indicators which acts as a fuel gauge so you can easily monitor battery capacity, and twin output jacks which allow two flashes to be powered together. Depending on which camera you're using, you will experience flash recycling times of 3.5 - 5 sec, 50% faster than times with AA batteries.

Hundreds of Flashes

Replaces NiCads or Alkaline Batteries
Specially designed modules fit into the flash battery compartment to replace unpredictable NiCads or Alkalines.
50% Faster Recycling
With the QB1+ you will experience 50% faster recycling, and output will remain consistently fast even as battery charge is depleted.
Volumes of Flashes
The QB1+ will yield approximately 250+ full power flashes per charge in manual mode and more than 10000 flashes in automatic mode.
LED Displays
Easily monitor your unit's condition, power status, on/off, and charge status/complete with LED indicators.
Faster Charging
The QB1+ charges fully in 3 - 10 hours with standard charger. Charge light goes out when charging is complete.
Twin Output Jacks
Twin output jacks allow two flashes to be powered together.
Electronic Circuit Breaker
The unit's electronic circuit breaker prevents damage to flash or battery. Automatically shuts off, and cannot be turned on without a module plugged in, preventing accidental drain of the cells.

    I own 3 QB 1+ and 1 QB 9v and I think the quality is quite good. Their service department on the other hand is way over priced. Remember these are expendable products. They won't last forever no matter how you use them. So when it comes time to have them serviced it would be nice not to feel like your equipment is being held for ransom.

      I use the QB+1 when I take team photos. It has never let me down. It beats the heck out of lugging around a crate of AA batteries and helps my Nikon flash to recycle faster.

        Profession Portrait/Wedding Photographer and this is the second one I own. Fast Charging time lets me switch from one QB1 while the other is charging. I am able to leave an 8 hour event with a full battery after about 1k shots

              I use this product to power the flash attachment for my camera. It holds a charge for a great length of time.... not certain how many, but enough that I can shoot a wedding and reception with it. Lightweight, doesn't take up much area in the camera bag. This is the third QB1 I've owned over the years as they do tend to expire... I've been very please with each.

                I typically avoid flash photography like the plague, but when you must, missing a shot while your flash recycles is completely unacceptable. This power supply solves that problem.

                        I put this off for awhile, but now that I have it I'm glad.
                        - Faster recycling, from 4-6secs down to 2-3 secs and that makes a big difference when working with your subject.
                        - I put two Vivitar 285HVs on this unit, mounted high and low on a light stand, w/33" umbrellas and it makes a great full-figure model light.
                        - I recommend two of these, instead of the turbo, so you have a backup. If you buy the larger turbo and it goes out, you have nothing; this is unacceptable at a wedding or event.
                        - Last note, the newer MB style connectors, which replace the 4-AA batteries, it locks well and does not move. Yes, the battery door does not close, but the main thing is that it locks and does not move, I don't mind the battery compartment does not look pretty, nobody cares.

                          Comments about Quantum Instruments QB1 + (6V) Battery:

                          Using a Quantum Battery 1+, I shot 400+ photos in a dark Masonic Lodge. Battery worked like a champ. Only problem was recycle time between shots. Not sure if it was the flash or the battery causing the delay. Flash head did get warm, so I believe I was over taxing the flash. I still strongly recommend this product. If you are looking at doing similar session, I'd recommend the Turbo model.[...]

                          I use the Quantum Battery 1 plus with my Nikon SB-600 flash. I bought this one as an upgrade from the Quantium QB1 compact. The flash usage is about twice as long and it is useful for those multi-hour conventions/shows.

                          Of course, if you buy this, remember to buy the connector cable to your flash since it is separate.

                          I photograph weddings and needed a battery pack that would last about 6-8 hours without worry. Someone recommended this battery to me and said it would last all day. I've photographed two weddings with it in the last two weeks, and both times, the battery has completely drained after about 3 1/2-4 hours of use. The first wedding I photographed getting ready and formals for three hours, then looked down to see that it was at the 50% charged mark. I was surprised that I had gone through that much juice so fast, but figured I had at least another 3 hours left on the battery. 20 minutes later the ceremony starts and the battery went from 50% charge to 0 charge instantly and just as the bride was walking down the aisle. Bad.
                          Second wedding, after 3 hours of getting ready and formals, I looked down and the battery was at the 50% charge again, so instead of risking the same result as above, I took off the battery, and used my Canon external battery pack instead (which is half the cost of the Quantum), and shot without fail the ceremony and reception. Wish I hadn't spent the money on this battery. It does not stayed charged as long as I need a battery to last. It would be fine for portrait and engagement sessions, though.

                          This battery will no doubt make your life easier...until the short battery life has you looking for your backup. Granted, it does last longer than the normal batteries required for your flash. This product is definitely user friendly, not too heavy, and compact. Just make sure you bring a spare! Lasts roughly 5/6 hrs of avid shooting, so not so great if you're in the middle of a wedding but perfect for engagement or shorter shoots.

                            Great product, better recycling times that batteries. Also, maintain power over many shoots. I just used during a talent show, almost 1,000 shots with all 4 status lights On.

                                Have become way tooo expensive. Bought 2 new ones a while back and one has a hard time holding a charge and the other still isn't as solid as one I've had for 10 years...
                                The quality of the new ones is very dissapointing especially for such an increase in cost.
