And how many rude comments there are..

Well, hey, you must be from a younger generation than us in our late 70's... so we needed the instruction as the instruction booklets don't get it... and, guess what, I'll send you some of my 8 track music and see if you can figure that out. ha

We put together a list of a few such power banks here: www.powerbankexpert.com/power-bank-with-pass-through-charging/

Yes, power banks, just like other batteries have a limited lifetime. For more info check out this article: www.powerbankexpert.com/how-long-does-a-portable-charger-last/. But your issue might or might not be related to the battery lifetime. There might be other causes for it. It would be a good idea to take it to a local electronics repair shop to check it out before buying a new unit.

@@PowerBankExpert Thanks so much!

No dumb questions here. You can use any type C cable with your power bank. But please be aware that not all cables are the same, so charging speed might vary.

Power banks have built-in converters and can output different voltage values. But for calculating the Wh capacity, you should use 3.7 V as a reference. Check out this article for more info: www.powerbankexpert.com/how-to-convert-mah-to-wh-calculator/

Thank you so very much

In that case, the power bank will be charged. The car charger port works only in one direction...you cannot use it to charge your car's battery. However, if you charge your power bank while the engine is running, the car battery will not get depleted...only if the engine is off.

It's ok to charge it up to 100%, it won't do that much damage to the battery life. What's more important is not to let it drain out to 0% all the time. As much as you can, try to charge it up once it hits between 10% and 20%. It can go to 0% too but try not to make a habit out of it.

​@@PowerBankExpertbest explain ever it was so important to know

I'm not that familiar with that product, however, a blinking green light is generally a sign that the power bank is charging. Maybe you're using a slow charger and thus it takes a lot of time to see progress? Have you tried changing the charging cable and/or the wall charger? Also, please check out the user manual. In there it's generally detailed what the charging process should look like.

Try going through this article: www.powerbankexpert.com/power-bank-blinking-but-not-charging/

I believe you're referring to pass-through charging. Please see this video for more details: kzfaq.info/get/bejne/oceijNSg0dqlf2g.html

You should be able to do that.

I haven't heard of this power bank model until now, but it seems to have a micro-USB charging port. So you should be able to charge it with a micro-USB charging cable

@@PowerBankExpert thanks for the reply. I have a one with one type C and one type A. Both presumably say 18W. I hope for the best.

If you're referring to the power bank in the video. It was already almost full when I filmed. Maybe I did not make it clear enough. But it did not charge to 95% in a few seconds. I also have a video with a ROMOSS power bank...check my other videos on the channel.

Any charger should do, but for fast charging, they recommend 9V/2A: store.mi.com/in/item/3204500003

@@PowerBankExpert Thank you so much for the reply sir

Usually, power banks with built-in solar panels are very inefficient. Especially the ones with a single solar panel (some have 3-4 foldable panels and are slightly better). If it works as planned, the single solar panel can fully charge the power bank in about 20 days or so if left under direct sunlight. However, if the solar panel is of lower quality than expected, or if the power bank is not put under direct sunlight, then I could expect to see effects like the ones you mentioned. So I'm not so sure if you can do anything to fix your power bank, unfortunately.

Thanks for the reply, but no, although mine's only a single panel, I don't think my problem's anything to do with the strength of solar energy it receives; it's the polarity of the connection between its solar source and the battery. Whenever it shows solar energy being received, it starts to flatten the battery instead of charging it, If I knew how to identify the internal connection between the solar part and the battery part, and I could simply reverse it, then I believe I could start to get some benefit from its solar generation. I can only guess this reversed polarity symptom is due to an error in its original assembly.

@@sleepyjohn8324 If it's like you say, then maybe you can still return the power bank to the store you bought it from. These types of defects are usually covered by the warranty.

@@PowerBankExpert No, I must have had it 5 or 6 years now, so sadly long-since out of warranty. Apart from that, it would have been hard to convincingly explain my symptoms to an on-line supplier in a foreign country with limited English language ability. So that's why I thought I'd try posting on this specialist site here to see if anyone has any idea about how these solar batteries are connected up internally. Hate throwing anything in the bin!!

@@sleepyjohn8324 ​if you had it for 5-6 years already and the problem started just now, then it's not likely for the wiring to be wrong. Most likely the issue is with something else...maybe the circuitry. However, since you're saying that the USB charging goes just fine, then I don't see why you can't use it for longer as a regular power bank. Solar charging would be quite inefficient if it worked anyway. USB is the best way to charge your power bank with. Also, if at any time you decide to throw it away, please make sure to do so in a place that specifically collects batteries. Disposing of it in the general trash bin is very harmful to the environment.

That's normal. Most power banks don't come with wall adapters. Simply use your phone's adapter.

If the power bank supports that, for sure you can. But only a minority of power banks offer dual charging (USB type C and micro USB)

The first one is a no-name brand called "Blow", while the 2nd one is the INIU BI-B61 10000mAh. You can see more details here: www.powerbankexpert.com/iniu-22-5w-10000mah-power-bank-review/

As long as they are compatible, you won't damage the power bank even though the charger can supply more power than the power bank actually needs. The power bank will only "take" as much power as it can.

That’s funny because i’m actually using a battery pack is my replacement charger for my laptop because I can’t find the actual charger for it this should output enough watts to power on and charge

According to the power requirements of the Steam Deck, you'd need a power bank that outputs at least 45W. Here's an example: www.powerbankexpert.com/ravpower-portable-charger-20000mah-pd-60w-review/

@@PowerBankExpert Thanks very much…

If I remember correctly it was an Asus charger that came with a phone. You should be able to find similar and even better chargers online.

@@PowerBankExpert Thanks

You should be able to, yes.

No, they can be different. Power banks have regulating circuitry that will draw the power needed, even if the charging block can supply more power.

@@PowerBankExpert Thank you. Does the block wattage affect the time it takes to recharge a power bank. 12w vs 18w 5v/2a

@@edwardgreen5880 yes, it does. if the wattage is lower than the max input of the power bank, it will take longer to load. You should preferably use charging blocks with higher wattage.

@@PowerBankExpert Thank you.

It's difficult to know what the actual problem is without analyzing the power bank. Maybe this article will help you troubleshoot: www.powerbankexpert.com/power-bank-blinking-but-not-charging/

If the second LED light is blinking, then it should still be charging. It's possible that the first light is not working anymore.

Some power banks allow for dual charging. It depends on your power bank model.

Yes, you should be able to. Give it a try.

@@PowerBankExpert Thanks a lot

I'm not sure I fully understand the question. But the number of charges you will get will depend on the size of your phone's battery. A 20000mAh power bank could charge your phone up to 3-4 times. Here are more details on this topic: www.powerbankexpert.com/how-many-mah-to-charge-phone/

How many time can I fully charged 100% my phone battery

@@victoriotrevino9757 It depends on the capacity of your phone's battery

That is doable, however, the power bank needs to have a "pass-through charging" function. Not all power banks have it, so if you're buying a new one make sure it's clearly specified. For more info, check out this article: www.powerbankexpert.com/what-is-pass-through-charging/

Yes, they can

Try to press the power button two times in quick succession. If that doesn't work, try a long-press on the power button.

@@PowerBankExpert I already tried it and it keeps turning on, no matter how much I press the button the flashlight does not turn off

Do you mean it was left plugged into a wall charger with no power? If so, it doesn't seem like a normal activity.

🤣🤣🤣

You need to fix your brain first 😜

Don't be "that" guy...

It's a power bank. You don't have to work for nasal to know how it works. Jaysus Murphy *eyeroll*

Like......its a power bank. Were not not at chernoble or aushwish.

Any USB type C charger that can output at least 18W

Are you trying to charge the power bank from your laptop? Or the other way around? If you're trying to change the power bank from your laptop's USB port, then it most likely will take a very long time. These ports generally output low amounts of power. Please try to use a regular wall socket charger. It should work.
