Very inferior to rechargeable batteries

    I specifically bought this for the ability to use it at home for night reading. Mine does not light when the battery is dead, and it takes several hours to charge. And the old fashioned plug-in recharge means you can't use it with modern USD chargers (like in my car!). (They do make a car charger ($$)). However, the real reason for the 1 * is that it doesn't hold a charge for nearly as long as modern AAA batteries. I can camp for a week and get 1-2 hours of use around camp every night (I dim the light a bit when reading)with AAA batteries, but the charger pack only made it to day 4!

    Is there a rechargeable battery kit for...

    Is there a rechargeable battery kit for the black diamond Apollo lantern?

    I dont see one for the lantern specifically, but you are working with 4 AA batteries. I would recommend the Goal Zero Guide 10. It is a charger for both AA and AAA batteries (4 at a time) that you can charge via USB, cigarette lighter socket in your car or by the Goal Zero solar panels. I use the Guide ten to keep my iphone charged, camera, flashlight and walkie talkie. Very versatile. Here is the link:

    Hi James,

    Yeah, it's the NRG, item# BLD0354. It's the only way to go, IMO.

    One advantage over rechargeable AAA's

      after a lot of use i have found only one advantage over rechargeable AAA's. This unit is pass-through capable,meaning that with the provided plug or a USB adapter you can use the light as it charges, even from a dead battery. if you have other AAA products rechargeable AAA's might be a better option but its up to you.

      Back to the original question: Why not just use NiMh AAA?

        No one seems to be able to answer the important question here: Spend $10 on a 4-pack of NiMh AAA that you can use with other things (and work with any NiMh recharger) or spend $30 for a proprietary pack that can be used with nothing else? If BD or anyone else can somehow demonstrate that the NRG2 doubles the lifespan of 4 NiMh rechargeable AAA then it might make a compelling argument...otherwise don't waste your money.

        I am thinking the same thing. I can buy the rechargable batteries for about $10 to $15 dollars and use them for any device I want.

        By far the best solution to this problem.

        I have the NRG2 and a Brunton solar power pack. The advantage is that there is a USB to Plug adapter that fits. my Brunton gives me 1- 1.5 extra charges and so far I havent seen a USB charger for AAs. also I have been using this pack of over 9months of both total discharge and running as a spare light while plugged in and havent seen any decrease in battery life like you see with rechargable batteries. so it looks like to me that the over all lifetime is worth the price.

        I have been looking at this and hoping for a USB charging solution. Black Diamond's web site and available instructions and pictures reveal nothing however.

        If anyone can provide info on how to charge this power pack using USB I'd appreciate it.

        I found a usb adapter for the plug and it works great with my brunton solar charger as a back up. i havent come across a usb/solar charger for AAA's

        Goal Zero makes a AAA adapter for their Guide 10. It's a usb/solar charger I use with the Nomad 7 and Nomad 13. It gets the job done charging AA and AAA batteries.

        Does anyone know if this has any additional...

        Does anyone know if this has any additional benefit to just buying 4 rechargeable AAA (increase runtime, decreased wieght, etc.) Also, what it the charge time?

        The benefit is that you don't have to keep buying AAA batteries, but there's no weight difference and I haven't noticed a difference in runtime either, so if you buy rechargeables it shouldn't make a difference.

        Nope. I just finished disassembling one and the rechargeable power source is actually just 4 AAA batteries glued together. Save your money and buy a pack of standard rechargeables.

        what's the AC Input for this? is this...

        what's the AC Input for this? is this auto-volt? (able to accept 100-240 voltages)?

        BD's website instructions ( doesn't mention the power compatibility, but at the first glance at the picture I see interchangeable plugs for countries that provide 240VAC power through wall sockets. Without tech specs to support it, I'd feel safe plugging it into 240. Although you can always order it and read the plug itself, and return it if it doesn't support 240. Gotta love Back Country's policies for things like that.

        it is a 110-240 ad/dc adapter.
