Thanks for the clear review!
Thank you! 🙂 🙂 🙂
Thanks for the non-sponsored review. They are more like ads than actual user feedback.
Looks like a solid product. Too bad I missed out on the Lunar New Year discount.
Nitecore advised that this solar panel doesn't have an auto-reset function. Which means if it's momentarily shaded by clouds and tree cover etc. the phone charging circuitry doesn't like the fluctuating power and doesn't charge properly. Hence best practice to charge power banks as you did!
The wattage output you got is quite good. Actual solar panel outputs are usually around half of the rated claimed output (STC standard testing conditions at 25 degrees Celsius with artificial sunlight). Nitecore is pretty transparent about the actual average rating as you mentioned.
Oh wow! Clearly you're an expert on all those complicated stuff (i.e.: volts, watts, etc..)
Today was my day 1, I'll have more updates along the way! ✌🏻
@@Hong.Wanderlust I'm looking forward to a long-term review. Especially if it fails from overheating and how the build quality and materials hold up.
@@rcatz3248 Sure thing! I'll keep using/testing it out! 😀
Looks great! 👍
It’s impossible to charge 13k mah, with fast chargers of 20w it takes 6 hours to charge 20 k mah
Hi Manik!
Yeah, I have received tons of feedback on this, and I believe I made the error of using an old 'battery pack' that doesn't actually hold its charge.
I will be doing a follow up video with a better (brand new) battery pack, as well as a USB volt-meter for accuracy. 👍🏻
Finally!!!!
hi hong are you able to test the FSP30 from nitecore also.
Goal zero Nomad 28 plus is much better, because it can link 2 panels with 8mm plug to generate twice output
13k mah in an hour. your power bank sure still ok or not? that's crazy fast.
Well, that's based on my unscientific calculations of charging up 45% of my 30,000mAh power bank. 😂
More watts, nice.
What you say is bad, because 45% of your 30000mAh power bank is 51,3 Wh of your 114Wh powerbank (30Ah*3,8V), this speed is not possible with 28W solar panel.
Hi buddy, many thanks for the comment. Yeah, you're absolutely right, many other viewers have also informed me that my calculations were indeed inaccurate. Also, I figured out after the filming, that the batteries in my power bank are probably quite degraded (due to age).
I am planning a follow-up retest video real soon! 😀
@@Hong.Wanderlust I look forward.
I love the review, but the calculation has to be wrong.
There isn't a solar panel that is in the 21-28w (that's Watts, Wong) that will charge a battery bank THAT fast. In fact... do this: Let your battery pack go down to 0% again, and charge directly from the wall outlet. Something that is WAAAY faster than solar. You will see it won't do 15,000mAhs (that's Milli-Watt-Hours) in that amount of time.
Lastly... what did you mean, enough to charge your cellphone "twice"?
My Samsung S21 Ultra, and competing iPhone 13s, have around 4,500mAh batteries.
15,000mAh would charge either of those three times.
I'm not trying to be rude, but I just don't think 15,000mAhs can be gained from the sun, even in full sunlight. I would love to be wrong though.
You should do the same test with a little USB charging tester, that shows you how many watts, mAh and mWhs pass through a USB-A or USB-C device. I have one, and it works great for testing the charging rate of anything USB! Look for Klein Tools ET920.
Hi Chris, thanks for sharing!
I have been receiving a few similar messages too and plan to do another test video soon. One possibility might be that because my portable power-bank is an old one (like 3 years old?), the batteries inside don't perform the way they did as compared to new.
I do indeed have a USB tester, and once I receive my new portable power-bank, I'll do an update test! ✌🏻
@@Hong.Wanderlust Awesome. Also, I apologize. I mistyped originally and put Wong, but meant "Hong".
Also, I made another mistype where I said mAh was "milliwatt hours". There IS a rating called mWh. But I meant to say mAh = "milli-amp hours". Sorry to confuse the issue more.
One last thing, I know those different readings like volts (V), watts (W), amps (A) and their corresponding smaller readings for smaller devices like milliwatt hours (mWh) and milliamp hours (mAh), might seem confusing. But you could find a short video on RUclips that reviews it and you would be an expert in very little time. The easiest way to remember it for smaller devices, is that milliamp hours is how much your device can hold, like your cell phone or your power bank.
Whereas milliwatt hours is used more for rating the electricity flow as it charges up the same cellphone or power bank.
It's weird, but you'll get it after a short video or two.
Keep up the great reviews, I think I'm going to get one of these solar panels thanks to your review. They do appear to be better than other similar ones, and Nitecore is solid, in my opinion. And thanks again for replying!
@@chrislucas2324 No worries at all buddy, I did figure out what you meant. 🙂
And again, thank you for the tips, I will do more research along the way. For the longest time, I was just curious to know how many hours will it take to charge things up and never really dived into the technical aspect of things. That's all about to change though, as I am thinking of learning and adapting more sustainable options for home and work use.
Here in Singapore, we get an abundance of sunlight, and solar options should serve well.
And yes, in my humble opinion, products from NITECORE are really awesome, well built and robust. I have a few of their flashlights and never had to worry.
Yes the calculations are on the right track but using the wrong numbers. Looking at Hong's previous solar panel review you can see the power bank specs at 3mins 46secs. Output Capacity 12400mAh. This is due to factors such as circuit inefficiency and voltage conversions (power banks convert 3.7V to 5V USB). The power bank converts the 5V USB from the solar panel to 3.7v to charge itself. When you plug in your power bank to your phone via USB...you get the idea.
Hong, your videos are still excellent. You're putting content and product reviews for us to see and engage with!
Thanks Chris & Catz! Really really appreciate it! I am currently planning to do the 2nd review/test video sometime in the upcoming weeks, just waiting for ideal weather! 👍🏻 👍🏻 👍🏻
I can’t find it anywhere... is it normal ?
Sorry to hear that.. Maybe it isn't available in the country where you stay? 🤔
@@Hong.Wanderlust It might be (I live in France, where it is usually much harder to purchase cool stuff than in the USA or perhaps in Asia...) However, I checked ebay and could not find it either. I eventually bought the 30 W solar panel, but it doesn't have any stand 😢
Nitecore?
Very poor performance. Needs full sunlight. Will not work with even minimal cloud cover. Once clouds come, it will stop charging and not restart. Under similar conditions, this Nightwalker gives out 1W, driving my phone crazy with start-stop-start-stop charging.
The Nitecore Nps200 will give 5W and the Goal Zero Nomad 10 will give 2-3W.
Not a defective unit as I bought a few and the behaviour is the same.
You can leave the panel out in full sunlight at noon in the tropics for 2 hours with minimal cloud cover, and it struggles to give you 20% charge on your phone...
I'm actually planning a re-test, becasue it was brought up to me that the way I made my calculations were incorrect. Will be getting to it as soon as possible! 👍🏻
hello boss i need this product but how to can buy in Malaysia
Hello Darpan! I'm not too sure who the official dealers are in Malaysia, but I belive the @NITECORE official website offers international shipments. 📦

@@Hong.Wanderlust thank you so much for nice reply 💕
@@darpanmagar2466 No problem! 👍🏻 👍🏻 Feel free to let me know if the purchase is possible (or not). If it isn't, I can help try contact them from here. 👍🏻 👍🏻
How many units do you need? I'll sell it to you
Sadly it doesn't come near it in my test
Max 1370 mAh
Hello Simon,
I have been informed in quite a few comments that my math/calculations were inaccurate. (I am unbelievably bad in math). Have been planning to do a re-test video, and will do so soon!
👍🏻👍🏻🥳🥳
