Restore the old broken speaker, you can upgrade with a 10,000mAh backup charger + RGB LED lights. 

- Today I repaired an old broken speaker that someone had thrown away, I disassembled it, cleaned the speaker circuit,.... and I upgraded the speaker to a phone backup charger with a capacity of 10,000 mAh and flashing LED. rgb to make the speaker more complete, listen to music for a long time without battery life, and with flashing LED lights to make it more beautiful. After I completed the assembly, I found that this phone charger works very well, charges the phone quickly, and the speaker can listen longer. - Subscribe to the channel and turn on notifications to watch the latest videos, thank you :P + PAGE FB: / cungnhausangtao97 + Facebook: www.facebook.com /trandaohongphuc97 + TikTok: www.tiktok.com/@cungnhausangt... - Link to buy components at shoppe VIETNAM: + SDP fast charging circuit 22.5w IP5356 QC3.0 you can buy here for only about 30K Shop Smart Toys (KST): s.shopee.vn/9f1m25OnQr + 18650 battery: s.shopee.vn/8f9b6vIbxY - Link to buy components at shoppe VIETNAM: + SDP fast charging circuit 22.5w IP5356 QC3.0 you can buy here for only about 30K Shop Smart Toys (KST): s.shopee.vn/9f1m25OnQr + 18650 battery: s.shopee.vn/8f9b6vIbxY
