    I got two of the 100s and two of their 202s two months back. I think I paid $3.87 shipped for the 100s and $7 for the 202s, for $22 shipped total.

    They're nice to have as spares and to put in places you might want something an emergency--car, truck, tackle box, multiple bug out bags, etc.

    I don't think that they're perfect and Henrik doesn't like the lack of 2.1A support as a power bank, but it's better than nothing, I gather?

    Initial solar test not promising but intentionally did it under poor conditions to try to trigger an error. Looked good at first but then showed green at 3.7 volts which isn't fully charged. Will try again in more favorable conditions, still the more complex the charger aka multiple battery types etc etc the worst in my experience it works for solar. Still surprised some of my power banks don't work with it.

    edit.

    Will try again in better conditions.

    What solar panel are you using, and were in the world are you? I have a couple of folding solar panels (see my signature) 24W is my most powerful, though why i bought them when the UK only gets 2 weeks of sun in the summer and the rest of the time it`s windy cloudy or raining, maybe i should have bought a wind generator.

    Do you have a ups power bank, meaning it can be getting charged by solar while it is charging you charger, this stops the charger cutting out when clouds block out the light.

    I used a 16W Allpowers standard panel. Running a proper test with a 14W Allpowers high efficiency panel right now with a lithium ion protected Keeppower 16650 at 3.7 volts (same battery which failed the marginal conditions test). Also charged a dead LSD Duraloop using an Anker battery pack yesterday. I have several powerbanks. The F1 charger can actually do a pass through and is immune near as I can tell to charging errors.

    HJK is supposedly doing a review of this charger, Hopefully we can find out how bad it is for small li-ion cells.

    Here are the results. 3.7 volts charged up to 4.1 volts during weak winter sun with occasional clouds during the afternoon. 14W solar panel charger. Again a Keeppower Protected 2500 mAh 16650. I am feeling better about this but need to do another test. On a side note I have no scientific basis but really don't think the charge rate will kill anything including AA or 14500 instantaneously resulting in who the heck knows what. Sometimes the internet can blow (pun intended) things out of proportion. Or rather hope not as charged them both. LOL!

    Photobucket sucks and is down so will upload pics later.

    edit. On a side note 4.1 volts appears to be all it will take with the UC as it showed green when attempting to top off the last .1 volt using both the wall outlet USB and Anker power bank. Will test that again with another battery. Using a simple Xtar to top it off.

    edit. Ok photobucket it up. On a side note the 16650 had about 30 more minutes of charging on the MC1 to reach the proper 4.2 volts.

    Looks like things are going ok.

    I use to use Photobucket, But now i use Imgur it`s free and much better, and it`s easy to post your pictures on forums ect.

    More actual use testing. Charging at 1a.





    All the batteries charged up good this time. 4.2 volts on the Keeppower.

    Charged a mixed bag of older LSD NiMH. After charging with the UC put them in the XTAR.



    But the USB power supply was weak so pulled one out then did one that after.



    It's was actually ok as they were not in the XTAR for more than 15 minutes or so before being fully charged.

    So from that powerbank it did just fine. But then from an Anker 3200 it cut short at 4 volts (remember the solar cut short at 4.1). I suppose that's better than not terminating the charge but no expert on this topic. It's a PITA to charge in a wall outlet (but did totally work) as the cord is so short and it has gotta, sorta hang unless using the USB ports on my power stripe. So this IMHO is a mobile thing. Which still makes me wonder why the powerbank inconstancy? I tested it with a larger Anker, 13000 mAh and it seemed to work fully but didn't write anything down or really double check it. Going to test some more with a few more powerbanks. Overall my advice is to test it with whatever power supply first before depending on it. I was really surprised the F1 didn't work to charge lithium ion yet seemed to work with NiMH when using the UC. I gotta revisit that. Given the light weight and bulk will probably pack it to support my camera, takes AA and headlamps AA/18650/14500 using a compatible power bank. Still don't get why they all don't work.

    Mine is blinking red every few seconds trying to charge a 14500. 18650 works fine. It's not the 3 blinks/second for standby, so not sure what's up.

    Mine does a single red flash every 3 seconds, when no battery is connected.

    It should be a constant red while charging that turns to green when the battery is full.

    I have charged 14500 with it just fine but will test that again once the Tiara as used one up. Did you try another battery?

    I've also just charged an Olight 14500 and a Keeppower 14500 with mine with no problems. Have you tested that 14500 in another charger?

    I'll be testing mine with my solar panels over the next weekend.

    HKJ's review is out now http://www.candlepowerforums.com/vb/...rger-Olight-UC and it says that the charger does not restart when the voltage drops.

    On my solar panel test today, it was clear sunny day for at least 5 hours, and I tested charging NiMH AAs, which appeared to have charged fine. I will test again in cloudy conditions as well.

    And if anyone is interested, I found a perfect DIY case for it, using an empty Mentos gum container. The case is fairly small and lightweight, is splashproof and protects the charger from magnetising other things in my backpack when I go hiking:

    Default Re: Olight UC (Universal Charger) Magnetic & USB input

    I've got a protected 18650 which has had the positive button mashed down by a light. The olight charger blinks red and doesn't charge with it. The solution is to add a small steel BB to the magnet that's on the mashed positive, charges fine now that it can make contact.
    This makes me think that the magnetic contacts are needlessly big and heavy, two small rare earth magnet spheres could sit in pressed copper pouch/sleeves instead.
    The brighter the light, the darker the shadow.

    Having the ability to use this charger with a Solar Panel would be a big asset for me. I'll do some testing with a Solar Panel as well when I get home from Florida in March.

    Please continue to post your Solar charging results for us and I will do the same.

    The Nitecore F1 is a good charger/powebank for use with solar as it has an ups function, meaning it can be getting charged by the sun while it is charging your phone ect, And if the clouds block the sun the ups feature keeps your device charging.

    Noticed that when the cell is near full (say around 4.09v), it won't charge up to 100%... anybody has the same experience?

    I used a Keeppower 18650 battery case to house it. So far so good...

    Yeah, my UC is the same. If the charging is interrupted anywhere above 4.08v or so, it will just turn green when reconnected.

    I think it's a great charger for "just in case", but you still need a proper charger on hand.

    Thanks! And I agree... This is a good charging option to be stucked inside your edc bag or organizer... for the times you are away from your 2-bay or 4-bay charger.

    Same here. I don't know but happened with solar so think it might have something to do with spotty charging above a certain voltage as it didn't happen at a lower level. Also don't know why it refused to work with the F1 to charge lithium ion and the Palm but did work with those for NiMH. All of that said for a crazy UL pack item (tested to verify it works with packed power bank as it did with my others) it's good enough. Won't replace my other chargers but it gets packed when needed.

    - or you could consider it a feature, slightly undercharging should extend battery life, right?
    So it's more of a "lost on a desert island" feature than a practical, everyday one.

    Some observations after using it more.

    1. Seems to shut down a bit short of a full charge with NiMH or lithium ion. Not so bad as would rather be 95% charged than over charged aka missed termination.

    2. Charges AA/AAA at .24 to .27 amps at 5.10 to 5.09 volts. Starts are .12 to .15 amps then increases. Seems to pulse charge NiMH by the looks of the meter.

    3. 18650 charges at .74 to .75 amps at 5.10 volts.

    So far seems kinda solar compatible but testing that again in a day or so.

    If it's nearly charged (around 90%), you have to connect the charger the the battery FIRST, then plug it in. I think it says this in the manual, but I could be confusing it with another charger. And I can't find my manual or one online to confirm.

    Will try that but the NiMH batteries were nearly depleted and they did the same thing. Remember as it was the last ones I charged. Though again rather leave that party a bit early than stay late...missed termination.
