The current Lidl ULTIMATE SPEED Portable Jump Starter With Power Bank battery specification is:
- Battery: Li-Ion / LiFePO4
- Energy: 38.4 Wh
- Internal battery capacity: 12,000 mAh at 3.2 V
- Available USB power-bank capacity: about 6,650 mAh at 5 V
For your PicoMuon, the important figure is the 6,650 mAh at 5 V, since that’s what is actually available from the USB output.
A rough runtime estimate:
- PicoMuon at 100 mA -> about 66 hours
- PicoMuon at 150 mA -> about 44 hours
- PicoMuon at 200 mA -> about 33 hours
However, the more important question is whether the jump starter has an auto-shutoff feature. Many jump starters and power banks turn off when the load current is too low, which can be exactly the problem you’ve experienced with the PicoMuon.
If you have the Lidl jump starter already, an easy test is:
- Fully charge it.
- Connect only the PicoMuon.
- Leave it running for 2-3 hours.
- Check whether the PicoMuon is still powered and logging.
