Since downloading rebate apps on phone, my phone battery drains very-very fast. Prior to these apps, I didn't have to charge my phone, but every few days (seriously)!. Now that I have all these apps on my phone (ibotta, MobiSave, Shopkicks, SavingStar, Checkout51, BerryCart, KrazyCouponLady & several survey apps, as well) ...my battery barely makes it through 1/2 a day, if that! So I NEEDED something to extend it while I was out shopping or in general.
I also use my phone a lot for taking PICS, which as you know also drains your battery. Then after shopping, I have to scan in bar codes on products & receipts by taking PICS to submit for these rebates, so more draining. Not to mention all the push-notifications that seem to be never-ending & ever-draining on my phone ...sigh, the joys of technology! ;-)
It was through Shopkicks that I even saw the Dynex™ DX-2603 portable charger advertised for a sale price that I just couldn't pass up. I thought ...what have I got to lose! I knew I needed to do something! So I went to my local Best Buy, showed them the item, which thankfully they had in stock and made my purchase!
I tell you what ...so far, so good! It has gotten me out of a crunch a few times, as my battery drains so fast! I haven't had it long enough to know "how long" it actually extends it, as I've never had to "fully charge" my cell phone with it (not even sure it will do that). However, it's made my cell last several hours until I was able to get home to recharge both cell & this charger.
That's the important part, remembering to charge it AND bring it with me! My only "complaint" -though it may be the same with all external chargers, since I'm new to this is that it's a bit bulky & takes more space in the purse. Plus, when it's plugged into my phone, it does make it a little more "difficult" with using my phone, since it "dangles' from the bottom of it.
I also wished the plug was a full sized to fit my S5, but I guess with so many types of phones out there, it's hard to make it work for all of them. What I mean by that is it only fit's into 1/2 of the plug. My phone has one plug, but it has a "divider" of sorts making one 1/2 larger than the other.
Anyway, for the price, I can't complain too much, as it's saved me several times. I've only had it a few weeks now, as of 5/28/17, so unless it stops doing what it's doing so far I don't see the need to get another one that has more "power".
So there you have it ...unless something changes drastically on its performance than this review will remain "as is"!
