Feedback from Customers

Some News from our Customers

Jochen H. from Berlin wrote us about our harvester (translated):

"... thank you very much for your great "Harvester".

2450 km and 21000 hm (difference in altitude) I have done this summer. From Berlin via Slowenia and Croatia and back to Munich. Many mountains, plenty of crushed stone road, a lot of distance with pushed bike. During 23 days I never needed a mains plug to charge the harvester. My Garmin, my i-pod, my mobile and my tent light, there was allways energy left. Even if I forgot to charge my mobile during the day, there was enough energy left in the harvester. Heat and heavy rain had no effect on the operation.

Thank you for the great harvester,

best regards Jochen H."

Neuer Professional Bike Energy Harvester USB-P5

Lumi-Con's Professional Bike Harvester USB-P5

is now available.

The new Professional Bike Energy-Harvester has a compact design and simple mounting features. It features an enormously increased charging current from hub dynamo.

The new dedsigned dynamo charger circuit allows charging currents up to 1A into the battery at speeds between 15 to 35km/h (see fig. below). The respective power is 8W out of a "normal" hub dyanmo.

For charging from mains a new USB-booster was developed which is powered from a standard USB mains charger. (Micro-USB-Plug, 5V/2A).


The Harvester USB-P5 offers a 5V-USB-Unit with up to 1A output current - compatible to all usual smartphones. The harvester is buffered with a battery unit with a capacity of 21Wh, thus it can be used independent from bike charging for a long time (e. g. as powerbank or if the bike stands). The harvester has two independent charging inputs, one is fixed permanently to the hub dynamo, the other can be connected to a mains charger.

Display (3 LEDs) for charging, reday, empty
Package 112 x 62 x 31mm
