Review on 💡 HUAHA 10pcs USB Mini LED Lights - Keychain Lamp with Smart Touch Electrodeless Dimming Switch for Laptop, Home Decor - Emergency Security Lighting (5 Warm + 5 White) by Devin Maselli

That's great, my backup power can last more than a day. Has proved useful during recent PG&E outages during the fires. They are equipped with 5x soft white and 5x daylight. To be honest I wish they only sold 10x soft white, both work great, but in the event of a power outage, soft white bulbs are less likely to damage your eyes. Especially if it's your only source of light. Either way both are great, very bright and with a USB power bank it lasts all day. They were very useful to me during the recent California fires. They cut my electricity for 4 days in a row due to strong wind. Then there were 2 more shutdowns but like 2 or 3 days. I can't tell you how helpful they have been.
