BONAI10000mAh Portable Charger for Heated Vest, 5V 2.1A Battery Pack for Heated Jacket with Dual USB Output & LED Flashlight for iPhone iPad iPod Android and More

This works great. Just follow directions and you can use anywhere.

Fabulous deal for the priceThis is the experience with my other two phone banks:I have been frustrated not knowing if I abuse my power banks or if they are just not working right. I got one last year, and it cost around $100. It was great until I tried to daisy-chain and play music from my cell phone with it connected in the wall charging. I am fairly sure that is what did it. Then I got a $40. model from another maker. It seemed to work ok at first. It was unclear to me if it was charged, and when it had been charging once for awhile, and my phone wouldn't revive after losing a charge that came particularly fast. For awhile I couldn't revive the phone at all. 45 minutes went by and no charge. I plugged it into the cigarette lighter and after awhile my phone charged, but was acting strange. My phone bank did finish the charge. That was the last time I got it to work.This model:I haven't had much trouble at all. This charger works faster than the other, and notice the price is much less. This one has an on/off switch, and I cannot figure out if it controls the ability to charge or to not charge. But it seems to not matter; I do know though that the switch does control an LED light that acts as a flashlight. That is a very nice and unexpected feature. I feel like my cell phone charges from this unit very well, and not at all slow which is what I had expected.I am very happy that there is something like this for my 5S iPhone for this price. My only problem is with the connector. While it is efficient in that you only need one - both for charging the power bank, and for charging the phone from the power bank, the connector gets dislodged quite easily, which is an easy fix due to the availability of these connectors. I have literally dozens of them, and they are quite inexpensive.All this is why I feel as though I have a very good power bank for my iPhone 5S for much less money than others that I would think should be better.

I got this for a heated vest and it works pretty well. Kinda surprised actually it lasts as long as it does. I wasn't expecting it. With the vest on high it lasts 3.5-4 hours. *Your use maybe shorter or longer depending on the number of heating elements.* This battery also seems to fit in the vests the best. Its taller vs wider and the USB socket is in the side instead of in top. Much better fit because the USB ports in the vest are @ 90°. Both vest run pretty consistently with the time too. Only draw back is it does take a while to charge, but as long as you give it overnight ~6-8 hours it should be good. The other packs I have are just a little shorter in time, but not much and they run slightly longer. Maybe something they all can improve on. Overall Bonai is decent in my book. And @$15, thats faily cheap. The two others I have were over $25 ea. I will buy another Bonai.

I use my phone as a hotspot for internet access when visiting client sites, so my phone’s charge can become depleted quite quickly during the day. Locating an outlet to use a wired charger is not always convenient, so I purchased this power bank in anticipation of my next customer visit (fortuitous as the conference room we were located in was woefully lacking in electrical outlets).Wow!I was able to charge my phone 3 times before having to recharge the bank. The bank recharges quickly so you are up and running again in no time. When traveling, it is just SO much easier to pull out this bank when stuck in a plane/train terminal where all the power outlets are already in use – and forget going through contortions to reach the power port on a plane!What I REALLY love about this little device though is how long it will hold a charge. After my last trip I threw the bank in my electronic gadgets basket and forgot about it. A few months later my power went out unexpectedly and my phone was low on charge. Ugh! Crossing my fingers, I dug this out and oh my gracious, it still had 75% charge left on it (the lights indicating how much charge is left is most helpful!). I was able to charge my phone twice before the power came back on.The weight is a little heftier than I had anticipated, but I don’t mind as it gives the device a very solid feel. The design is slim enough so the bank will easily fit into your pant’s pocket.While I initially pooh-poohed the need to have a flashlight included with the device, I found it to be oh-so-helpful when my power went out.The two ports to charge multiple devices has also come in very handy.Since purchasing, I have recommended to several friends who have also purchased and were very happy. I highly recommend this device!

Nice case, so far quite robust. Takes a while to get fully charged but holds a good charge and gives it up readily. Not a QA product but does the job @ 9880 mah discharge

Fantastic item, easy to use and a must if you using your phone throughout the day. Charges so quickly too.

Sehr zufrieden

Super batterie externe qui m’a permise de charger quatre fois mon iPhone 8+. Le petit plus de cette batterie c’est la lampe torche!La couleur est super originale aussi comparée aux autres batteries que l’on peut retrouver sur le marché.La batterie est assez légère aussi.

Artikel:Ich brauche momentan ein paar Powerbanks, in allen unterschiedlichen Größen. Für verschiedene Geräte ist es heutzutage leider notwendig, dass man eine mobile Ladestation dabei hat. Diese Powerbank wirkte für mich ausreichend, um unterwegs meine GoPro laden zu können. Sie hat eine Kapazität von 10000 mA/H. Zwei USB Ports, wo man zwei Geräte gleichzeitig laden kann. Bei Ports haben 5V und liefern 2.1 A. Die Powerbank hat eine Status LED-Anzeige, wo man den Akkustand grob ablesen kann. Diese ist unterteilt in 4 LEDs, wobei jede LED für 25 % steht. Leuchten zwei, ist die Powerbank also zwischen 25-50 % geladen. Zusätzlich hat die Powerbank eine kleine Notfalllampe mit an Bord. Diese wird durch längeres Drücken der Power-Taste aktiviert und deaktiviert. Im Lieferumfang befindet sich noch ein kurzes USB Mini C Kabel, eine Anleitung und ein wirklich liebevolles "Danke". Die Powerbank kann mit jedem Handynetzteil geladen werden. Je nach Netzteil dauert das Voll laden der Powerbank ca. 8-10 h. Also wunderbar für die Nachtruhe. Die Powerbank ist hochwertig verarbeitet und macht einen stabilen Eindruck. Klar hat diese ein wenig Gewicht und für die Hosentasche ist sie wohl nicht geeignet. Aber in den Rucksack oder Handtasche passt diese immer.Fazit:Eine gute und hochwertig verarbeite Powerbank, die nur einen Zweck hat : Das mobile Laden ohne Steckdose. Und diesen Zweck erfüllt die Powerbank sehr gut. Deshalb gibt es fünf Sterne von mir und eine Kaufempfehlung.
