A few things I determined about its operation are: 1. When disconnecting the (micro) USB power the 5 Volt output power (at the Type A USB port )will drop to zero volts for about 200 to 300 msec and then switch to the boosted 5 volt output. 2. There also has to be a minimum output load for the output to be boosted. It was boosted when I had a 1 Kohm load, but it was not boosted when I had just had the meter (~10 Megohm) on the output. Then I just got the battery voltage. 3. The boosted output also seemed to have problems when supplying an output current near 1 amp. I believe that is is only rated for 1 ampere output current. **Q: My board charges my phone for 10 seconds, then get really hot and turns off and stops charging. Battery: 3.7v 16340 li-ion. Short circuiting? Help?** A: If your phone is a fairly new model my best guess is that board cannot supply enough current. The board I tested would only supply about 0.7 Amps. **Q: Why does the output only read 3.9V? I have 4V input.** A: When you say you have a 3.9V input, I'm assuming you mean you have a battery connected. If you have a charged lithium ion battery connected with the plus terminal to B+ and the minus terminal connected to B-, you should see 5 volts output on the large usb connector. Some of these modules (not sure about this one) require a minimum load to be connected to the large usb connector before the full 5 volts is output. Try plugging in a phone and then check the voltage. It's also possible that you've got a bad module. In that case, try another one. **Q: can i connect a solar cell directly to this to continuously power an esp01 charging in day and running on on battery at night?** A: You'll need a Diode to block reverse current to the Solar panel. Would not recommend it though as there will most likely be too much losses in the conversation and solar panel most likely will not put out enough current. But in theory it would work. ## Frequently Bought Together - Onyehn 12Pcs 5V Boost Step Up Power Supply Module Lithium Battery Charge Protection Board for DIY Charger,with LED Display,USB and Micro Port - MakerFocus 3pcs NRF24L01+PA+LNA Wireless Transceiver RF Transceiver Module 2.4G 1100m with Antenna and 3pcs NRF24L01+ Breakout Adapter with 3.3V Regulator on-Board for Ar duino --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/372950688-onyehn10pcs-5v-boost-step-up-power-supply-module-lithium-battery](https://www.desertcart.tn/products/372950688-onyehn10pcs-5v-boost-step-up-power-supply-module-lithium-battery) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-07*
