WARNING: Questionable IP65 RATING...WATER INTRUSION!

3 out of 5 stars

WARNING: Questionable IP65 RATING…WATER INTRUSION!
Note, I do NOT fully understand exactly what IP65 rating entails, but this is what I found online:"An IP65 rated enclosure gives protection against low pressure water jets from any direction, as well as condensation and water spray. It’s suitable for most outdoor enclosures that won’t encounter extreme weather such as flooding."If I were to go by this rating definition, I would say it's not IP65. I designed a wooden housing that would allow this charger to be exposed to sunlight but at the same time, keep the upper section sealed from liquid intrusion. I installed it for an outdoor project with this unit upright at about a 60 degree angle.After 1.5 days of rain, the inside got quite wet. Refer to my pictures. I was unaware until I noticed my light coming on without me doing anthing. I instantly suspected water intrusion which was exactly the culprit. I tore open the unit and voila, water was everywhere on the inside.After wiping the unit down and letting it air dry properly, all functionality returned. So if you think you can let this battery get pummeled by rain or get drenched, you are going to be in for a rude awakening. After opening it up and seeing how many openings there are to the inside, it makes perfect sense how water made its way in. The rubber seal used to keep out water will invariably let water in. There are simply just too many openings. Take the IP65 rating with a grain of salt.As a final note, I would like to reiterate that I am not faulting the unit. It was clearly not designed to be left in the rain, but one would think an IP65 rating would be able to given the definition. Rain is essentially a low pressure spray and IP65 ratings are supposed to be able to keep out water from low pressure water spray. Regardless, I am well aware that I may have used it in a way it was never designed to be used. As such, I, the user am just as at fault for doing so, and for this reason, I don't fault the unit.Having said that, I would warn anyone to think twice if you think this product will keep liquid out as it clearly does not. Use in wet conditions at your own discretion. As far as the solar charging goes, if you don't intend on depending on it, you wont't be disappointed. It's better to just pretend it doesn't exist. As a battery pack, it seems to work fine but it's no Anker. I bought three and intend to use them accordingly now that I know. As to longevity, having opened it up, I am not holding my breath; it's cheap, what do you expect?

    Well like most customers on Amazon, I was nieve enough to think that this thing came charged. Well with a little charge. I believe I charged my phone 2 times and my earbuds once. Then I thought it charged with the sunlight. Haha yes it does. But very slowly. The solar part is for when you actually loose electric. It will recharge with sunlight. Just much slower that the electric from the wall.

    Battery life is AMAZING!
    Charges super FAST with my fast charging cord. ( Maybe even faster than when I plug it in the wall)

    Bought this after my daughter had one when we were on vacation to Florida last month.

    Best purchase for the price.

    This was a waste of money. I regret it 100%. I had bought it because it’s handy when you go camping, so I thought. I was only able to use it once to charge my phone battery. It only charge halfway. Now it doesn’t work to charge my cell phone. The only thing that works on it is the light.

    I actually bought two. Both do not work. I bought them at two different times. One when I went traveling and gave it to a relative but then it didn’t work to charge cell.

    I hope this review helps.

    Unable to stay on. Have two of them, same problem…

    Reviewed in the United States on June 18, 2022

    Verified Purchase

    So I bought this power brick for a simple purpose, to power a USB fan to circulate air while I was camping in my car for a weekend. (Got a bin full of silica beads to remove moisture from the air)

    The power bricks worked great! For about 1 minute to 7 minutes and 40 seconds……. Then they shut off the fan.
    Shows fully charged, turns off. Charge it for 10 hours like manual says, still turns off after a bit. Still showing full charge….

    I originally bought one of these and on day one, ran the fan for hours as a test, worked great. Charged it up overnight and went camping the next day. Noooooooope. Started turning off every couple minutes. About an hour of that and I'm done with it, just deal with foggy windows.
    I get back home, try a few days of testing, charging/ect. Nope, now it wont work for longer than a minute at a time. Try turning the light on, that stays on forever, but the fan turns off after, you guessed it, 1 minute.
    I order a replacement from Amazon thinking "Ok, defective unit, lets try again". I pull it out of the box, press power, it shows full charge. Want to guess how long it lasts?

    1 minute…. Try the old one for S&G's, it manages to last 7 minutes and 40 seconds. I go back to the new one, 1 minute. I go back to the old one again, 1 minute….

    I cant rely on this thing, returning right after I finish this review.

    Another thing worth mentioning out of sheer weirdness, and I took a picture to prove. I read the entire manual, it says to contact customer service team, or "After Sales Support Team" and "we will help you as soon." Yes, the sentence ends after soon. Fine, translation error, ok.
    But, there's zero emails, phone, address, any contact information at all for these "teams" to be able to 'help me as soon'. In fact, there's not a single company logo or name in the entire manual at all. It says "Powerbank" on the cardboard box it shipped in. Well, that's an item description, not a company.
    The company should be Errbbic right? That's what this amazon page says. And that's what it says on the item itself on this page right? Even other customer pictures shows the item with text "Errbbic" printed on the item.

    Take a close look at my picture, showing two recent products. That company text is missing. So I either received a knockoff product, or the company is realizing that the product doesn't work and is doing everything they can to distance themselves from it… Either way, returning.

    Hopefully this helps others in managing their expectations. And I hope you all enjoyed the novel.

    Odd battery life behavior

    Reviewed in the United States on October 17, 2023

    Verified Purchase

    I don't often review products, but I felt compelled to comment on this battery.

    I have used a lot of portable batteries. I own no less than five different ones. I was intrigued by this one because of its solar charging ability. That said, this is my LEAST impressive battery.

    Let's start with the solar. Yes, it does seem to work. No, it isn't great at all. To be fair the manual states that the solar is for "emergency use only" and should not be used as a means of charging. Well, that is definitely true. You should never epxect to get hardly any charge out of the solar capability.

    That's not what makes it a poor battery. It is poor because it has extremely odd charging behavior. There are 4 indicator lights for charge. The first two seem to last forever. Then the last two are stable for about 5 minutes of charging a cell phone. Also, when it charges it takes about an hour to get to 3 lights. Then it take seven more hours to fill the last one. It says it has a capacity of 20,000 mah, but that simply cannot be true. One full charge of this battery can barely charge my phone all the way once. I have another 20,000 mah battery, and it can easily charge my phone 3 times all the way. Maybe mine was defective, but I'm not impressed witth the capacity at all.

    Of note, the manual says to "charge the phone for 10 hours the first 3 times to unlock full capacity" No idea why it needs this. I DID do this, but the resulting capacity is still terrible.

    Unfortunately, I do not recommend it.

    Solar is a useless gimmick
    Capacity is terrible
    Charging rate and display is odd and makes no sense.
    Overall, there are much better options out there.

    Charges quickly and holds charge for fairly long time. Charge primarily with electrical hookup and then if I am outdoors supplement with the sun. Works both in Europe and US with only connection adapter and no need for a converter. Worth every penny. I have charged two phone simultaneously with this charger that I have had for over three years. Yeah!
