SiKER Power Bank (Grey)

I bought this for my daughter who just moved to New York and her phone battery wasn’t lasting while she was traveling back and forth on the subway. I didn’t want her phone dying while she was trying to find her way! She complained and said this portable battery was big and heavy. I did not check the size before buying. It looked pretty compact to me but it was bigger than her phone. I talked her into using it for a while. She now carries it everywhere and uses it all the time and is able to charge her friends’ phones as well!

I purchased these units to keep our devices powered in case of a long-term outage during an upcoming storm. It turns out that the storm didn't knock out the power, but these have been used quite extensively. They are a bit larger and heavier than other similar more expensive products, so may not be suitable for pocket use. But for keeping emergency devices such as phones, and other devices such as tablets and speakers charged for a long time, it's perfect. The battery capacity seems to be on par with another product that I purchased that was 3 times the price, so I wouldn't hesitate to recommend this product.

We have purchased many portable chargers and they have worked for a bit and then they don’t turn on any more. We purchased this for my 16 year old son who took this charger on a school trip to Costa Rica for 10 days, he only used this portable charger, and it lasted the whole trip!! It charges way faster then plugging it into the wall. We now have to take it from my son because he only chargers his stuff on this portable charger. It holds a charge for soooo long that we are going to get one for everyone in the fam because this is the only portable charger that hold a charge. It is also a MUST have if you have an iPhone 6! We also have charged the Mac with this.

It works well, but I find it really heavy to transport it in my purse. But with it to put it on the carryon for a long trip! We took it to Europe and it was a life saver. But I haven’t taken it anywhere since then just because it’s heavy to carry it around.

This is one of the best purchases I've ever made online. This bank charged my Amazon Fire HD8 Tablet from dead to 100% and my iPhone 6S Plus 3x from less than 5% to full (plus about 90 minutes of YouTube videos while plugged in after it reached 100% for the third time). That is insane!I've had smaller 5,000 MAH battery banks that could only charge the Fire HD 8 Tablet to 12% or so bedore dying.The battery bank is big and it feels about a lb in weight but I actually like that. It might not be the go-to for something to throw on your pocket for a quick day out but it will fit. This is more of a bank to put in a backpack, car, or purse.It will allow for pass-through charging (that means charging things through it while it's being charged itself for those who aren't familiar) until it gets full.The 2.1 amp USB port charged my iPhone full in about 30 minutes. It's really fast. The other port is a typical 1 amp.This bank does take about 6 hours to fully charge, but that is expected with such a massive capacity. I bought a second one of these because I'm not very good with planning. Even I find it nearly impossible to mess up with two of these massive banks.I can't say enough good things about this.

I was so excited to revieve this product. My husband and I have terrible phones, we cant afford to get new ones at the moment because im currently pregnant and on bed rest. Our phones batteries are terrible and need to be charged more often. My husband was going on couple camping trips this summer so i figured this would come in handy just in case something happened while he was camping.I was reluctant to buy it due to several comments that the battery stopped charging shortly after purchasing. But after looking at several products I finally dove and bought this one.At first i loved it ! It was much bigger and heavier than I anticipated.I used it one time while at the beach and it charged multiple phones no problem . Even my portable speaker.I started using it around the house at times so I can read my kindle and charge my phone. I noticed shortly after my phone would stay at the same charge. Then i noticed I had to be off my phone in order for it to charge on the unit. Now the charger unit itself will not charge . it will only charge to one dot and that's it.I was hopeful I wouldn't be writing a "unit stopped charging" review but unfortunately I am.I bought it in June, and only used it a handful of times. Its July and useless. My husbands trip hasnt even happened yet so now on the search to buy a different unit that hopefully doesn't stop charging.Needless to say, im disappointed. Good price, but not good for long term.I gave one start because it only lasted one event.

This bank works awesome and charges for hours but is is VERY heavy and much bigger than the photos lead you to believe. Probably around 5” wide by 7” tall??

This is a great battery backup, I used it as backup power for some LED lights I use when camping. Even when outside temp was 9 degrees F this battery bank held it's charge and replenished my devises all weekend.It's a bit large and heavy, not really made to be in your pant pocket but it is good to keep in a laptop case, back pack, or purse.Height and width size is slightly larger than current cell phones but probably twice as thick.
