SUMMARY

The discussion focuses on finding a pocket-sized external battery compatible with a handheld DVR that requires a DC5V 2A power supply. The manufacturer's external battery pack, which uses three Alkaline UM-2 (C) batteries, is not available through US dealers. The DVR also includes a 3.7V, 2000mAh lithium-ion internal battery. Participants suggest exploring options such as a 4-cell battery holder for C batteries available from Hobby Engineering and a D battery holder from Radio Shack.

PREREQUISITES
  • Understanding of DC power specifications, specifically DC5V 2A requirements.
  • Familiarity with battery types, particularly Alkaline UM-2 (C) and lithium-ion batteries.
  • Knowledge of battery holders and their compatibility with various battery sizes.
  • Basic research skills to locate alternative battery solutions online.
NEXT STEPS
  • Research portable battery packs that provide DC5V 2A output.
  • Investigate the specifications of lithium-ion battery packs for compatibility with handheld devices.
  • Explore DIY solutions for creating custom battery holders for C batteries.
  • Look into retailers that specialize in electronic components for additional battery options.
USEFUL FOR

This discussion is beneficial for electronics enthusiasts, DIY hobbyists, and anyone seeking portable power solutions for handheld devices like DVRs.

I am looking for a pocket-sized external battery to work with a handheld DVR. The manufacturer does make an external battery pack, however the manufacturer of the device is located in Korea, and no US dealers sell it.

From the product manual, it states that the manufacturer's external battery pack runs on... 3pcs of Alkaline UM-2(R14/1.5V) (Regular "C" batteries I think.)

The manufacturer's battery pack hooks into the unit's AC/DC adaptor outlet. The specs are DC5V 2A.

The unit has an included internal battery, which a is 3.7[V], 2000[mAH] lithium ion battery.



Can you think of any pocket sized solutions to my problem here? What do I need to look for in a battery pack that would work? Thanks very much.

Radio Shack has a 4-cell "D" battery holder. For others, search the web.
