Review:The first one of these I received charged batteries fine, but after several uses the Micro USB power jack came off the circuit board. Amazon sent me a new unit, but this time the connection at the same jack was VERY flaky, not allowing a power connection unless the cable was positioned at just the right position. Even the slightest vibration would break the connection. I tried other cables with the same result, so it's clearly a problem with the Micro USB jack hardware. From the 2 units I've seen, they both have severe problems with the power jack. It might just be dumb luck (getting two defective units in a row), so if they send me another one, I'll update this review to let you know how it works. UPDATE 8/29/16. Seller / Amazon never made good on my complaints about replacement unit also having a bad Micro USB jack. So, I never got what I paid for, and that was when this item sold for $20. Apparently, once Amazon replaces an item, they must consider their involvement complete, even if that replacement unit is also defective. Caveat emptor. Read more

Review:This charger disappointed me so much that it took me over a year to gain the necessary composure required to write a review. At first I loved it, it worked well with my solar panel and would charge up my AA and AAA batteries without problem. I have a large family and so we chew through rechargable batteries at a pretty fast pace. Though it may not make much of a dent to the electric bill, I really enjoyed being able to charge up my batteries using Solar power and a portable solar panel that I already had. After a few months of careful, deliberately gentle use (the charges is made from very cheap plastic, so you know to treat it gently) the usb cable "popped out" one day when I picked up the charger one day. Or at least that's what I thought had happened. Instead, what had actually happened was that the entire usb port disconnected from the circuit board inside and came out of the usb port's hole in the body's plastic--still attached to the usb cable. I always treat my devices with great care and with gentle hands, and this charge is just so cheaply and badly made that the port just pops right off with hardly any pressure at all after a short amount of usage. Look at other reviews and you can even see someone included a picture of the disconnected port. Mine looked exactly like that. I wish I could recommend the product, I really do, as it started off great....but with how poorly this is constructed and how easily and repeatedly it breaks (across customers) I would advice you to look elsewhere for your recharging needs.

Review:I'm currently using the Tenergy Low Self Discharge AA Tenergy AA NiMH Rechargeable Battery 2000mAh Low Self Discharge Batteries 24 Pack and AAA Tenergy AAA NiMH Rechargeable Battery 800mAh Low Self Discharge Batteries 24 Pack batteries. With a mix of different devices, tools, it's necessary to charge maybe a single battery or 3 or 4. I have bought two of these as sometimes I need up to 8 batteries charging at a time. My son (and I, sorry I can't lie) have lots of "toys" and we go through batteries very quickly. Good for charging while: -Camping. Using USB Solar Charger (try for 2A or more). -Car Charging. Using 3.1A USB charger. -Wall Socket Charging. (Look for at least 2A. Many current (7/2017) wall sockets with built in USB ports will charge at 2A or more). Not Great for charging: -Using USB off a computer or laptop as sometimes current is limited to 500mA (or less). -Any USB port not capable of safely supporting 1A of current. -Any intermittent sources of power, like solar panels that are not in sunlight for a good amount of continuous exposure. The batteries charge, but can take all day. I made the mistake of trying to charge my batteries while leaving my solar panel in the car where throughout the day we didn't have continuous sunlight. Even with a full day in intermittent sun, I didn't see the green LEDs above my AAs (2000mAh) (though the AAAs (800mAh) were fine). This has been perfect for multiple situations both indoor and outdoors. No excessive heat generated. Easy to use. I originally bought this to run the SunJack CampLight (TM) USB LED Bulb 340 Lumens - Cool White (for Camping, Hiking, Fishing, Backpacking and other Outdoor Activities, as well as Emergency) , but ended up using it for everything from kids toys to LED headlamps. The battery pack ran that light all night as my son didn't want to sleep in the dark. My only complaint is that the battery cover is sometimes finicky to work one-handed since it's hard to open (maybe a good thing so that the batteries don't fall out), but I often have a handful of batteries in one hand and I'm trying to open the cover with the other. Pilot error obviously, so I'm not deducting a star. Great product. Bought a second one after using one for over 2 years. Read more

Review:I bought this charger as a means to charge AA and AAA for my GPS and flashlight when camping. It works well with my solar panel (40W Poweradd) however it will not work with my recharger (16000w Anker). I suspect it's because they both have the ability to "smart charge" which only serves to confuse the recharger and the Sunjack. That leaves me with solar alone to charge these types of batteries. I have the Amazon Basics High capacity NiMH batteries (both AA and AAA) and the Sunjack takes about 10 hrs to charge them. Using solar alone to charge them can take a couple days depending on sunlight strength and availability. Beyond that, my charger hasn't suffered any of the other problems mentioned in other reviews. I've even dropped it a couple times on rock with no damage. Read more

Review:The device works, and it does run from a USB 2.0 port, however the current is split between the batteries being charged. A USB 2.0 port produces about 0.5A, so if you are charging two batteries they get about 0.25A each. It does work, but the charge rate is very slow. Charging 2x "AA" batteries from flat takes 5+ hours. You would typically use this to charge batteries whilst you sleep, or to leave it on charge during daylight hours so that the batteries are ready for the nighttime. It's one of those things that falls into the catagory of "better to be looking at it than looking for it". It's a good idea to keep one in your car or suitcase. It's pretty small and you just might need it one day. If you're in a particularily sunny country it will probably work with a portable solar panel too. I use rechargable batteries a lot and I would not consider the SunJack USB battery charger as an everyday charger. I use the Ansmann 16+ at home and the XTAR VC4 at work - both of which are excellent. The SunJack USB battery charger is only for convenience, because it's so small and portable. Read more

Review:(My Original Review is below) Despite my original positive review, after 3 months this charger stopped working, the charge LED's just flash on and off even without batteries inserted, and upon inspection I believe it may be as a result of a dry-joint on the large Inductor but not having my soldering iron with me I can't fix. I haven't treated it badly, it broke despite sitting on a shelf with no harsh treatment. Others have said the USB connector is liable to break as well, and I can see that the USB connector is lacking the usual anchor solder points. Originally 4 stars, but as it broke, now revised down to 2 stars - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Exactly what I was looking for. A battery charger that charges AA/AAA batteries individually, with an indicator that tells you when they are charged (which seems to be reliable and not just a timer). Build quality is the only area it is lacking, but saying that I would be happy to accept that appearances can be deceiving. I have been using it for 2months with no issues, the springs on the holding mechanism are a little loose and the power connector does seem delicate and the plastic "door" cover is a little flimsy, but it does exactly what I bought it for and it wasn't expensive at £9.95 with free delivery. Recommended!! Bottom Line: I spent hours looking for exactly this at a reasonable price and reading reviews this was the only one that does what it is supposed to! Read more

Review:Very firm and rough charger, it's simple and that's what I was looking for, I don't want no screens, indicators etc. Just plug in and charge, et voila. Beware when opening the little cover though, it's thick, but it has 'teeth' that grasp on the bottom section of the charger too well and I feel like I'll crack it open instead of lift it sometime. Also another user has reported it just went berserk for some reason and stopped charging after 3 months, so that's a risk you have to be willing to take. 4/5, great, cheap and tough, not sure how it will hold up though Read more

Review:It's not had a huge amount of use so far but it seems to work. My initial reason for not giving it more stars is the build quality, I felt when opening the clear plastic that I was going to snap it but I'm sure that will weaken to the point of being easy, perhaps even to the point where its so weak it won't stay closed. But then... I bought it for the electronics and its ability to charge the battery not so that I can enjoy putting the batteries in and out or watching them charge. Read more

Review:Perfect product. It's so cool not having to plug this into the wall and just running it off any computer, TV or games console. I hope it lasts years. Seems simple and well built so it should. It's not super fast but it's fine, I'd rather not burn out my batts and I'm never that desperate. Read more
