Product Highlights
  • Replaces the Vivitar SB-4 AC Adapter

The Pearstone SB-4 is an AC adapter that allows the Vivitar 283 and 285HV flash units to be powered by 110V household current. This is especially useful for use in the studio. The adapter will also decrease the flash recycling time down from 10.4 seconds to 4.8 seconds, and it has a 6' (1.8 m) cord.

Note: The 283 and 285HV flashes require fresh AA batteries to be installed, even when using the AC adapter. With 285HV models manufactured after 2006, only alkaline batteries will allow the adapter to deliver proper voltage.

The SB-4 replaces the Vivitar SB-4 (239404) AC Adapter.

Note! NOT compatible with original 285 non-HV models, which required the SB-6 adapter.

Input Voltage 120V, 60Hz, 200mA
Output Voltage 200VDC, 4mA
Cord Length 6' (1.8 m)
Dimensions 2.4 x 2 x 1.5" (25 x 5 x 3.8mm)

      I bought this A/C adapter to speed up the recycle time of the Vivitar 285HV flash unit. It certainly powers the flash as advertised, but be aware that "fast" recycle time is a relative concept. A full-power recycle went from 15-20 seconds on fresh batteries to a measured 9-seconds on A/C power. This is about half the battery time, but it depends on your application whether 9-seconds will qualify as "fast" and be adequate. Of course, if you are using less than full power, the recycle time is proportionally faster, and then it can be quite snappy. I usually use the Vivitar for rim-light and fill at ¼-power or less, so this is not a big deal to me. Also be aware that the documentation recommends having alkaline batteries in the unit when using the A/C-adapter, as opposed to rechargeables, but I don't know why that is. When the flash is mounted on a lightstand, the A/C cord is a little short and may need some support, but this is a minor quibble.

      Altogether, this does what I need it to do very reliably, and I am quite happy.

      On the 285?

      It seems to work on my 283. As instructed the flash must be OFF. When you connect the adapter the flash is turned ON and then you use it normally.

      It seems to work on my 283. As instructed the flash must be OFF. When you connect the adapter the flash is turned ON and then you use it normally.

      On my 285HV,if the flash is OFF the adapter will not turn it ON. You have to turn the flash ON to make it work but I think it is only using the batteries. I do not think the adapter is powering the flash.

          Comments about Pearstone SB-4 AC Adapter for Vivitar 283 & 285HV Flashes:

          Read the B+H reviews before purchasing, but I'm unable to understand the reviewers that said it didn't fit correctly. The flash must be turned off before inserting the connector. There's a plastic tab that prevents you from inserting the plug if the flash is on. Likewise, once the plug IS inserted, you can't move the power switch.

          It WON'T decrease the recycle time. A fresh set of batteries takes the same time to recycle as the SB-4.

          Also can't understand the statement that it needs batteries installed. Mine worked fine without batteries, and a look at the schematic reveals that the batteries are disconnected when the power supply is correctly inserted.

                Comments about Pearstone SB-4 AC Adapter for Vivitar 283 & 285HV Flashes:

                Works as advertised except for the recycle time. I normally get a recycle time of 6 seconds on full power with fresh rechargeable or disposable batteries. I am using the VP-1 varipower module for manual control over the flash power. When I plug this in (with or without NiMh or alkaline batteries) the recycle time increases to around 10 seconds. I was rather disappointed with this as many other reviewers reported a faster recycle time. I tried it on both my older model Vivitar 283s with both of the two cords I ordered with the same results.

                Other stuff to note: The "ready" beep does not function with this attached. (Which could be good or bad depending on the situation.) Connecting it without batteries in the flash does not affect the performance in any way.

                I'm using my 283's as a replacement for studio strobes (as they are all I have.) Going cordless is obviously more convenient, but having unlimited power is often worth the tradeoffs in many cases.

                  • When Ac Power Is Needed

                  Comments about Pearstone SB-4 AC Adapter for Vivitar 283 & 285HV Flashes:

                  I own 2 Vivitar 283s and one 285HV. The 283s are about 15 years old, and the 285 is a fairly recent addition. Powerful and dependable workhorses to be sure. I've never needed anything more. But oh, the batteries!

                  I would blow through an average of about 8 batteries per flash during during photo shoots. And degrading recycle times as battery life dissipated could be agonizing.

                  Enter the SB-4 AC adapters. They are a no brainier to use, and just as dependable as the flash units. I enjoy a constant 2 second recycle time and never have to worry about battery life. For portability, I use painter's tape to secure the cord and adapter to the stand(s) holding the flash units.

                  What do I have? 3 powerful flash units that weigh practically nothing, controlled wirelessly so I can move them around at will, all of which are at the ready all of the time.

                  NOTE: Keep batteries in the flash units when using the adapters, or in some cases, the units will not function. I DO NOT USE THE RECHARGEABLE BATTERIES as I have heard this may cause problems.

                  NOTE #2: The female end of the adapter cord may seem too large for the socket on the flash unit... it is not. Make sure your thumb/finger is not pressing against the on/off switch on the unit, line up the notched edge and push firmly.

                  Enjoy!

                      Thanks to the Pearstone SB-4 Adapter I can fire up my Vivitar 283 flash within seconds. On family shoots that is exactly what is needed. Even though I supposed to have 4 AA batteries installed, it fires up the flash without them. Just the product I needed to continue using my Vivitar 283.

                        My flash is out of warranty and the capacitor needs a lot of rehab on the first use. This can kill a set of batteries before you take your first snapshot. This sb4 adapter allows me to recondition the capacitor in a few minutes (about 10 manual flash cycles). This gets the cycle times much shorter then I switch back to batteries.

                        The sb4 adapter is surprisingly heavy for its small size and I wish the power cable to the flash was about 5 feet longer but this is tolerable with a household extension cord

                                    I don't know everything there is to know about photography, so I know this is user error, but when I buy an AC adapter, I expect it to power the device that I am attaching it to. This is NOT the case with the SB-4. It only powers part of the flash and still requires FULL batteries at all times in order to work.

                                    Prior to purchasing, I had read that batteries needed to be in place in order for it to work, but I had just presumed that that was in order for the current to flow through.

                                    I bought the 285HV and the SB-4 because I was looking for a compact flash that was powered by AC for an installation. I'm sure it's a great adapter for a great flash, but it does not do what I would expect it to do. It's going back to the store.

                                    Makes a huge difference in refresh time.

                                          I use my flash for capturing multiple shots rapidly and need a fast refresh rate. With the power adapter I have been able to double the amount of shots I can get off before I run out of flash. One thing I wish though, is that the cord was a little longer. Love the product. Ordering a second one soon.

                                                Powers your flash. Manual says you need batteries in your flash too, but in mine it works without batteries in. Also, much faster cycle times than with AAs. Save some batteries, buy this! :)

                                                  Great for.283/285hv. Reduced recycle time. Reduced battery usage. I would pick one up if your a strobist.

                                                  I bought two of these for my Vivitar 285HV flashes. These work fine, note that you DO need to have fully charged alkaline batteries in the flash for this to work.

                                                  I knocked a star off because the plugs can be a bit tough to attach to the flash. I had to bend the pins on one of my flashes to make it work.

                                                  I would buy these again - they have improved my cycle time and allowed me to shoot for long periods without swapping multiple battery sets.

                                                  The cords are a bit short when you have flashes high on light stands - plan to have plenty of extension cords.

                                                    I use two of this AC adapters in the studio with 2 Vivitar 285HV flashes. With the SB-4 adapters the refresh rate is slightly faster and what's more important to me, the intensity of the flash bursts is always consistent. You can fire away for hours with no decrease in quantity or quality of the light. And of course, you hardly replace AA batteries anymore.For [$], they are a bargain.

                                                      Works great but you have to make sure and have alkaline AA batteries in the flash just to trigger it. Recycles are a little better with this adapter.
