Product Highlights
  • Single-Position Charger
  • AC Adapter

Anton Bauer's Tandem-70 offers a new approach to portable power. It combines all the functionality of a one position InterActive® charger with the convenience of a noise free camera mounted wide range AC Mains Adapter. The Tandem-70 will power even the most power hungry high definition camera from any worldwide AC source. It also doubles as a full function InterActive Charger charging any Anton Bauer Gold Mount battery in two hours or less. Weighing only one pound (450g) the Tandem-70 is the perfect addition to any field camera as a lightweight mains adapter and/or as a high performance charger. Meets all applicable regulatory requirements including CE and FCC.

Battery Charger
As with all Anton Bauer chargers, charging with the Tandem-70 is fully automatic. Mount any Logic Series battery to the Tandem-70 and it will automatically determine the appropriate charge routine and execute it.
The Tandem-70 will charge any Anton Bauer Logic Series Gold Mount battery including:
  • ProPac 14
  • Digital ProPac 14
  • TrimPac 14
  • Digital Trimpac
  • Hytron 50/100/140
  • Dionic 90/160
  • InterActive
    The Tandem-70 incorporates the exclusive InterActive communication between the battery and charger, which allows the charger to identify any Anton Bauer battery attached and determine the precise charge routine for that particular battery under its present condition.
    Three Stage Charging
    In general, the Tandem-70 utilizes a Three-Stage Charge Routine for each battery.
    DC Power Supply
    The Tandem-70 will automatically operate as an AC adapter once the camera or other device is switched on. An On/Off switch is not incorporated into the power supply (a green LED will light, indicating that the unit is operating as a power supply).
    Automatic Source Selection
    If the AC line voltage is removed, and a charged battery is mounted on the Tandem-70, power from the battery will be routed to the camera. When the AC line voltage is restored, the battery is reevaluated for a proper charge routine.
    Power Supply Yes
    Battery Bays 1
    Type of Charging Single Battery

    Ideal charger/AC for my camera

    I'm using the Tandem 70 as a charger for my AB Dionic 90 battery and also as an AC power supply for my JVC GY-HM700 camera. I've just started out on my own as a freelancer so I have to be extremely careful on the products I buy and the money I spend. I've been working with Anton Bauer products for over 20 years so I know they are reliable and a standard in the business. Right now I can only afford one battery so the Tandem 70 is an ideal unit for my usage. It's lightweight and attaches to my camera just like a battery. It will fully charge my Dionic 90 in about 2 hours and can even charge the battery while attached to the camera. I would highly recommend this unit for anyone who is in a similar situation such as mine and it is also great if you are traveling and want to reduce the amount of gear you have to lug around.

    The Good:

    We usually keep the Tandem chargers on our JVC GY-HM700 ENG cameras full-time. Coupled with an A/B Dionic 90 battery, that's less than 3 pounds on the back of the camera, which balances just fine.

    And since the unit is always there, it just takes a few seconds to plug into a nearby a/c outlet when shooting sit-down interviews, news conferences, live shots, etc. As a power supply, the unit easily powers the camera and a 25-watt camera light. Why use the battery if you don't have to?

    The Tandem 70 lacks a digital readout, but the charging speed/performance seems on-par with our more expensive A/B Interactive Dual/Quad base chargers.

    The bad:

    We own six Tandem 70's, all purchased in 2010. In the last year, two of them have failed (one twice) and required shipping back to Anton/Bauer for warranty repairs. That's not a good track record, especially since all of them will be out of warranty this year.

    They are also very expensive for what they are.

    Bottom Line: I recommend these units, primarily because it allows your camera to be plugged in anywhere...all you need is a power cord. But the high failure rate of our Tandems is a concern.

      Comments about Anton Bauer Tandem-70 On-Camera AC Power/Charger:

      Just purchased the JVC GY-HM750 and after researching the options I decided to go with the recommended Anton Bauer system giving me both a battery charger and AC adapter for the camera. When performing the first charge it took a few trys to get the battery to start charging properly, and I was initially concerned the way the battery was so tight when removing it from the charger. It felt like at first it had gotten jammed and that I was forcing to get it off. After successfully getting the battery to start charging the first time, and realizing it does lock on tightly, I have had no problems, and am pleased with the performance for both charging, and the simplicity of its use for plugging the camera in. It also balances the camera out very nicely.

              This charger/AC power supply saves me space and weight when I pack. By
              planning ahead I can keep my two Dionic 90 batts charged and use the power
              supply when needed.

                Comments about Anton Bauer Tandem-70 On-Camera AC Power/Charger:

                Having a power supply with your camera is a necessity in long interviews, but having one that is very light, small, and able to be tucked in your camera bag so that it is with you at all times is a major plus. This one won't be tripped over, nor will you forget to flip it back to "charge" like stand-alone Anton - Bauer chargers that most people use as a power supply, instead of buying a separate unit.

                BUT - the Tandem 70 is also a charger. Every time you turn off your camera with an Anton Bauer gold mount battery attached - it automatically switches to charging the battery. I know it works well with my Hytron 140's - but I have not tried nor read the specs to see if it also charges Dionics...

                The bottom line - don't be a fool - pick one up now. We are all short handed on crews these days, and instead of - "I don't need to bring a power supply because this interview will be short, and my power supply is just too bulky" - it is always with you when you need it. Mine is always in the side pouch of my Porta Brace bag, goes on the plane with me... And actually reduces the number of bricks I have to take with me when I travel, for down time during interviews is charge time for my Hytrons...

                        This is exactly what you would expect and hope the product to be. I use this to keep my HDSLR cage system going.

                          Used for Sony F900, DSR570, and 790 cameras. The only powersupply/battery charger that seems to work. Although it has a useful life of only 4-5 years it's the best one on the market IMO.

                            Love this charger and it is a must need for interviews so you can save batteries and save on your pocket book because other chargers can cost a pretty penny.

                              I plan on using this as my full-time charger, and since it is fairly new I do not know how well it will hold up to such abuse, but so far so good. This charger is a "must have" for the portable, always-on-the-go shooter. It takes less than 2 hours to fully charge my dionic 90's and with a little advance planning, I can get them all charged ahead of time. Plus, it works as an A/C adapter for the camera instead of the heavy-weight and cumbersome alternative A/C adapter.

                                  Light weight and balances out an HM 700 on my shoulder or tripod. Dose double duty as an ac adapter and a charger, worth every penny.
