Here is the test result of the S$29 “brand-less” Solar Power Bank I bought from SITEX 2015. It has 12000mAh capacity, 2 USB outlets and 1 micro USB inlet. It also has an emergency LED on the side.
Recharging Solar Power Bank with USB charger
- 28 Nov 2015. 2.20pm. Charged with Samsung Tab A USB wall charger.
- 5.5 hours later. 7.45pm. Charged 3 bars. Final bar still blinking.
- 6.5 hours later. 8.45pm. Fully charged. 4 bars.
- 6.5 hours to recharge the solar power bank using USB Charger.
Recharging Solar Power Bank under direct sun
- Done this across several days. Clocked more than 10 hours. No increase in number of bars, though blinking indicator says it is charging.
- This could be a fake solar charger because no sign of power increase under the sun for hours. It is a real power bank though.
Charging a drained iPhone 6 with a full powered Solar Power Bank.
- 10pm to 12 midnight. iPhone fully charged in 2 hours. Solar Power Bank still show 4 bars.
- Next morning, Solar Power Bank shows 3 bars.
- This guy could charge my iPhone 6 four times over.
- That means I can go without AC power outlet for a full day or 2 with heavy iPhone usage.
This brandless solar power bank is going to Australia with me.
Here’s a very similar device on bigamzn US$20. Remember to read the reviews first before buying.

Hi Adrian,
I am a fellow Singaporean who happened to accidentally stumble upon your blog. I am very curious to know after more than 2 years of owning the solar powerbank(you bought it in 2015, it is now already 2018), can you please tell me what are your thought of it after using it for more than 2 years? I would be very grateful to hear what you have to say from your user experience after using it for more than 2 years.
Honestly, I think the solar panel is not working. When I put it under the sun for many hours, it doesn’t charge up the power bank at all. Have to spend more for a real solar power bank. So right now I am using it as a regular portable charger, though it doesn’t last very long anymore.
