Does Not Charge My Phone Fully; Unreliable
580639
I was very happy to receive this item, because it is cute and compact, so it fit perfectly in my purse. Unfortunately, it did not work as advertised. I followed the unit charging instructions precisely, but when I connected it to my iPhone, it only charged it about 50% before it was depleted. On subsequent attempts, its performance deteriorated further. On my last attempt before returning it, it did not manage to charge my phone even 20%. I really wish that it had worked as advertised. As it is, it would a bad thing to rely upon when an extra charge is needed.

Barely gives me one full charge on a iPhone 6 plus

I won't bother you with the technical specs of this phone. It was easy to set up, comes with the cable to charge it via USB and that's it. It actually provides decent protection for your phone so that's a plus.

After my first full charge that's when I started struggling with this product. It gave me enough extra battery to not worry about it for the entire day and then some. The next day when I plugged it into my computer to charge, it charged up a few minutes and then all of a sudden stopped charging and then started again without moving it at very random moments. After trying very hard to get it to the max I realized in use that it didn't fully charge.

Then comes my third attempt at this. Plugged it in and watched it for a while to make sure nothing weird happens, after about 20 minutes I felt pretty confident I could just leave it all night to charge and to my surprise next morning, it was completely discharged.

Maybe I'm doing something wrong but I believe that for such a simple thing it should just work out of the box. Returned it shortly after purchasing

I was pretty excited to get this, but after the first month, it was not consistent or reliable with charges (Amperage, Volts, etc.) unless I got a lemon. And for me, that's just unacceptable in a charger.

It seems that only a minority of chargers put out a strong enough current to wake my LG phone and charge it.  Most do not charge my phone even though they charge my Kindle.  The ones I received from this source do not.  The source company sent me a second charger when the first did not do the job, but the second did not do so either.  I guess the company treated me reasonably well, but the device is not serving me well.

Only charges my Galaxy S5 2 full charges until it dies when it should charge it around 3 and a half times

This unit never reaches 100% charged while connected to a power source.  The V5 power input does not recognize the charging cable.  You have to apply force and move it around; however, as soon as you let go of it, it stops charging. The unit charges well from the sun (if you're satisfied with 75% charge capacity), and item seem a bit overpraised for the quality of this product.

Sometimes has issue when getting near full charge where it keeps trying to connect and disconnect.

Not sure if I was sent a defective unit but this does not charge properly at all. Have tried different devices, in all of the available USB slots, always seems to trickle-charge my devices. Phone gains a few percent per hour and estimates around 9-12 hours to fully charge at 30%. When plugged into quick charge, it doesn't even recognize it as a quick charging port.

I'm getting some weird issues not too far into using this. I have to keep it plugged in more often than not because sometimes, despite having a full charge, it just turns off. I need to troubleshoot yet, but this has really made this purchase pointless for me.

i had my phone charging in this for about a whole day and when i finally went to go get my phone it wasn't even fully charged... it was at 50%

Meh...it works okay, but the major flaw is that if you leave the phone on the charger overnight, it shuts off when the phone is fully charged, thus the phone starts draining again and is at 75-80% when you take it off the charger in the morning. Seems to me that defeats the purpose of the charger in general and makes little or no sense from a functionality standpoint..

I used this to charge my iphone a handful of times over the course of the a month after purchasing. The lightning connection would frequently fall out -- this could be the fault of my phone, but I think the short cable was partially responsible, as it made it difficult to charge anywhere other than while laying flat on a table (couldn't charge it in my bag or the cable would fall out). I could tolerate this inconvenience, but the Jackery Bolt stopped charging fully within 3 weeks! After charging my iphone, the Jackery was unable to return to a full charge even after being plugged in overnight. It now stays stuck at 1 of 4 LED lights (the lowest level of charge). Perhaps mine is defective -- others might have better luck with battery life.

While the concept is good, the device's components, build quality and performance leave something to be desired.
Does it do what it claims? Yes, but poorly.
No matter what I tried I could not get the device to indicate a full charge (100% charge indicating light flashing even when wall charged for hours).
2500mAh battery may be sufficient for flip phones, but is simply inadequate for today's smartphones. This would only add about 50% to my Galaxy S3's battery.
When placed in full, mid-summer sunlight, the device seemed to shut itself off (overheating?).
During a week-long camping trip, I was forced to leave my phone in airplane mode and use it sparingly to mostly just take pictures.
IMO, this product would be worth the money if it's solar panels were larger, it's internal battery was at least 50% larger, and the functionality issues were corrected. Ideally this product should be able to Fully recharge a dead phone once a day, and it simply falls short.
As for the lights... they work and are useful, but are insignificant. And who wants to further drain the device's battery using the light, when it already doesn't have enough power to do what I bought it for?

This battery pack is okay. I may ask the company to see if they can replace it, I may have a somewhat defective one.  My issues are as follows:

1. Does charge in the sun! But it charges very slowly. Actually, it charges rather slowly regardless.
2. It charges my devices slowly and inconsistently. It may be the cord, as it seems very touchy - just moving the cord a little stops it from charging.

At least it does seem to hold the number of charges that it advertises. But you basically have to let your device sit there, charging, and not touch it (otherwise it can randomly stop charging), for several hours to get it charged in any meaningful way. So it's fairly useless as a quick charge on the go, but it can be an okay last resort if you're stranded somewhere and need a charge but you have to be very patient.

This product does work, but not well. My original plan was to use it as a hub, for my desk to charge my various electronics. Once I plugged it in, I noticed that my phone was barely charging, so me being a tech guy I went and used my usb multimeter to measure the power, to my dismay the "smart charger" determined my phone only needed 500mA, but my phone needs 1 to 1.5 Amps to charge. I tried to charge my tablet, which needs 2 to 2.4 amps, and again, the "smart charger" determined it only needed 1 amp... This charger does technically charge, but not at the rate it's supposed to...

Good concept, but charger often stopped charging midway and I would have to disconnect, then reconnect the usb wire to get it to keep charging
