Credit Card Power Bank, WECODO 4000mAh Ultra-thin Wallet Sized External Battery Charger Built-in 2 IN 1 Lightning & Micro USB Connector Cable for iPhone iPad Samsung LG Moto Phone

**5/17/17 - Good Customer service goes a long way. The seller reached out to me and wants to make things right. So I lifting my review to 4 stars for now. The product did recharge my Iphone well. It was very convenient. Seller assures me the included cable it very reliable. Maybe I just got unlucky with the one I received. Time will tell on that piece.DOA. Had a charge when it arrived but I cannot re-charge it. Cool idea but this version is not ready for prime time. Even if I could charge it there are design issues that should be solved. The Iphone cable does not appear it will last. Very thin. The ports are confusing and they have a lightning extender when none is needed.Next version may be better. And the concept of an always attached lighting cable is a good one. But this version is not ready.

Zero StarsThe first time I fully charged the backup it seemed to work but after only a couple more uses the backup seems to be dead. Within a couple weeks the charging capacity diminished to almost nothing in the first couple weeks but I kept trying it since there's no way to know how much charge there is on it. I didn't use it on a daily basis because I wanted it there for emergencies when I'm outside and I have a low battery on my iPhone. This thing has never proven to be dependable and I've always had to use another larger backup that I have in my car that hold 3x the charge and always works, but isn't as small and convenient to carry around. I'm throwing this WECODO 4000mAh in the trash now.

This product does not hold a full charge for long and when i thought i had this item fully charged and expect to get a full charge with my cellphone guess again because you wont get it. im considering returning this

This power bank is a slimmer power bank...but it is MUCH larger than credit card size. I do like how it will charge both android and iPhone with its included/attached hybrid mini charging cable. It charges well and can easily be held in your hand with your phone.

I absolutely love this charger. It has a type of hidden area to where an attachment is. I almost didn't find it but thank God my sister's husband tinkers with things. Works great for his I phone. Try this charger for sure.

This actually charges pretty quickly, holds it for a decent amount of time and charges my phone well in a short period of time. I have been wanting one for a while and finally decided to purchase this and I'm happy i did.

This thing was bigger than expected, was hoping it would be closer to credit card size but thicker.

I have received a replacement. I must say I was wrong that I reviewed it as one star.I'm sure the one I received before the replacement was defective due to shipping perhaps:The power bank is light, fast to charge my iPhone and fast to be charged.I'm very happy!Thanks

Very compact battery with cables build in. Perfect for travel or the wife's purse.

Stopped working after exactly two uses. I fully charged the portable charger but yet it will no longer charge my device. A disappointing waste of money.

This "CREDIT CARD.....ULTRA THIN...WALLET SIZE" product is HUGE!!!!!! I would love to see the wallet this can fit into.

Good to use as portable, so no issue for me

Use only 1 time after that it not working anymore .

Can't figure it out. Won't charge...

This arrived broken and not inside its packaging. The charging port was unusable, so it's useless.
