Exhibit 10.34

Amendment to Lease Agreement

                                  AMENDMENT TO
                                 LEASE AGREEMENT

Effective Date: February 1, 2003

      I.S. Capital, LLC (LESSOR) and Mobility Electronics, Inc. (LESSEE),
entered into that certain Standard Multi-Tenant Office Lease dated July 17, 2002
(the "LEASE"). The Lease provides that Lessor will provide janitorial services,
the cost of which will be included in Lessee's RENT and proportionate share of
OPERATING EXPENSES, as those terms are defined in the Lease. The parties wish to
amend the Lease pursuant to this amendment (AMENDMENT), and provide instead that
Lessee shall be responsible for all arrangements and payment of the expenses
associated with janitorial services provided to Lessee's leased premises
(PREMISES), in consideration for a reduction of $1,100.00 per month in Rent.

      Additionally, Section 2 of the Lease's Addendum accounts for a "FREE RENT
PERIOD" during Lessee's initial months of occupancy, in lieu of a Tenant
Improvement Allowance, in consideration for Lessee's direct payment for its
tenant improvements costing no less than $303,000. Section 4.1 of the Lease
defines Rent to include all monetary obligations of Lessee to Lessor under the
Lease except the Security Deposit, which by such definition includes the Tenant
Improvement Allowance and therefore any credits in lieu.

      Accordingly, effective as of the date of this Amendment, Lessor shall be
relieved from any obligation under the Lease to provide janitorial services to
the Premises, Lessor shall reduce the monthly Rent by $1,100.00 each month that
Rent is due, and the first month in which Rent is due after the Free Rent Period
(November 2003), is recomputed to $3,152.10. Correspondingly, Lessee shall be
relieved of, and Lessor may not demand payment of, any janitorial expense as it
relates to Lessee's Rent or proportionate share of Operating Expenses for the
Premises, and Lessee's first Rent payment becomes $3,152.10.

      This Amendment does not affect Lessor's obligation to provide any
janitorial services to the common areas of the project, which remain as stated
in the Lease. In the event of any conflict between the Lease and this Amendment,
this Amendment will control. The parties acknowledge that the effective date
stated above is correct, even though this Amendment was not executed as of the
effective date.

      The Lease shall remain in full force and effect except to the extent
amended hereby.
