                            WARRANT TO PURCHASE STOCK

THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR THE SECURITIES LAWS OF
ANY STATE AND, EXCEPT AND PURSUANT TO THE PROVISIONS OF ARTICLE 5 BELOW, MAY NOT
BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND
UNTIL REGISTERED UNDER SAID ACT AND APPLICABLE STATE SECURITIES LAW OR, IN THE
OPINION OF LEGAL COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER OF
THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS
EXEMPT FROM REGISTRATION.

Company:           MOBILITY ELECTRONICS, INC.
Number of Shares:  5,000 (subject to adjustment as provided herein)
Class of Stock:    Common
Warrant Price:     The Designated Price, as defined below, per Share (subject to
                   adjustment as provided herein)
Issue Date:        September 3, 2003
Expiration Date:   The tenth (10th) anniversary of the Issue Date

         THIS WARRANT CERTIFIES THAT, for the agreed upon value of $1.00 and for
other good and valuable consideration (including, without limitation, as set
forth in that certain Amendment to Loan Documents, dated August 25, 2003 (the
"August 2003 Amendment"), between MOBILITY ELECTRONICS, INC. (the "Company") and
SILICON VALLEY BANK ("Holder")), the Holder is entitled to purchase the number
of fully paid and nonassessable shares of the class of securities (the "Shares")
of the company (the "Company") at the Warrant Price, all as set forth above and
as adjusted pursuant to Article 2 of this Warrant, subject to the provisions and
upon the terms and conditions set forth in this Warrant. For the avoidance of
doubt, this Warrant is the "August 2003 Warrant" referred to in the August 2003
Amendment (notwithstanding that the Issue Date is in September 2003 rather than
August 2003).

         As used herein, the term "Designated Price" means $7.59 (which is the
average closing price per Share reported for the 5 trading days immediately
before the Issue Date).

ARTICLE 1. EXERCISE.

                  1.1 Method of Exercise. Holder may exercise this Warrant by
delivering a duly executed Notice of Exercise in substantially the form attached
as Appendix 1 to the principal office of the Company. Unless Holder is
exercising the conversion right set forth in Article 1.2, Holder shall also
deliver to the Company a check, wire transfer (to an account designated by the
Company), or other form of payment acceptable to the Company for the aggregate
Warrant Price for the Shares being purchased.

                  1.2 Conversion Right. In lieu of exercising this Warrant as
specified in Article 1.1, Holder may from time to time convert this Warrant, in
whole or in part, into a number of Shares determined by dividing (a) the
aggregate fair market value of the Shares or other securities otherwise issuable
upon exercise of this Warrant minus the aggregate Warrant Price of such Shares
by (b) the fair market value of one Share. The fair market value of the Shares
shall be determined pursuant to Article 1.3.

                                       1
<PAGE>

                  1.3 Fair Market Value. If the Company's common stock is traded
in a public market and the Shares are common stock, the fair market value of
each Share shall be the closing price of a Share reported for the business day
immediately before Holder delivers its Notice of Exercise to the Company (or in
the instance where the Warrant is exercised immediately prior to the
effectiveness of the Company's initial public offering, the "price to public"
per share price specified in the final prospectus relating to such offering). If
the Company's common stock is traded in a public market and the Shares are
preferred stock, the fair market value of a Share shall be the closing price of
a share of the Company's common stock reported for the business day immediately
before Holder delivers its Notice of Exercise to the Company (or, in the
instance (if applicable) where the Warrant is exercised immediately prior to the
effectiveness of the Company's initial public offering, the initial "price to
public" per share price specified in the final prospectus relating to such
offering), in both cases, multiplied by the number of shares of the Company's
common stock into which a Share is convertible. If the Company's common stock is
not traded in a public market, the Board of Directors of the Company shall
determine fair market value in its reasonable good faith judgment.

                  1.4 Delivery of Certificate and New Warrant. Promptly after
Holder exercises or converts this Warrant and, if applicable, the Company
receives payment of the aggregate Warrant Price, the Company shall deliver to
Holder certificates for the Shares acquired and, if this Warrant has not been
fully exercised or converted and has not expired, a new Warrant representing the
Shares not so acquired.

                  1.5 Replacement of Warrants. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, or surrender and cancellation of this Warrant,
the Company shall execute and deliver, in lieu of this Warrant, a new warrant of
like tenor.

                  1.6 Treatment of Warrant Upon Acquisition of Company.

                           1.6.1 "Acquisition". For the purpose of this Warrant,
"Acquisition" means any sale, license, or other disposition of all or
substantially all of the assets of the Company, or any reorganization,
consolidation, or merger of the Company where the holders of the Company's
securities before the transaction beneficially own less than 50% of the
outstanding voting securities of the surviving entity after the transaction.

                           1.6.2 Treatment of Warrant at Acquisition.

A) Upon the written request of the Company, Holder agrees that, in the event of
an Acquisition in which the sole consideration is cash, either (a) Holder shall
exercise its conversion or purchase right under this Warrant and such exercise
will be deemed effective immediately prior to the consummation of such
Acquisition or (b) if Holder elects not to exercise the Warrant, this Warrant
will expire upon the consummation of such Acquisition. The Company shall provide
the Holder with written notice of its request relating to the foregoing
(together with such reasonable information as the Holder may request in
connection with such contemplated Acquisition giving rise to such notice that
can be provided to Holder without violating applicable federal or state
securities laws), which is to be delivered to Holder not less than ten (10) days
prior to the closing of the proposed Acquisition.

B) Upon the written request of the Company, Holder agrees that, in the event of
an Acquisition that is an "arms length" sale of all or substantially all of the
Company's assets (and only its assets) to a third party that is not an Affiliate
(as defined below) of the Company (a "True Asset Sale"), either (a) Holder shall
exercise its conversion or purchase right under this

                                       2
<PAGE>

Warrant and such exercise will be deemed effective immediately prior to the
consummation of such Acquisition or (b) if Holder elects not to exercise the
Warrant, this Warrant will continue until the Expiration Date if the Company
continues as a going concern following the closing of any such True Asset Sale.
The Company shall provide the Holder with written notice of its request relating
to the foregoing (together with such reasonable information as the Holder may
request in connection with such contemplated Acquisition giving rise to such
notice), which is to be delivered to Holder not less than ten (10) days prior to
the closing of the proposed Acquisition.

C) Upon the closing of any Acquisition other than those particularly described
in subsections (A) and (B) above, the successor entity shall assume the
obligations of this Warrant, and this Warrant shall be exercisable for the same
securities, cash, and property as would be payable for the Shares issuable upon
exercise of the unexercised portion of this Warrant as if such Shares were
outstanding on the record date for the Acquisition and subsequent closing. The
Warrant Price and/or number of Shares shall be adjusted accordingly.

As used herein "Affiliate" shall mean any person or entity that owns or controls
directly or indirectly ten (10) percent or more of the stock of Company, any
person or entity that controls or is controlled by or is under common control
with such persons or entities, and each of such person's or entity's officers,
directors, joint venturers or partners, as applicable.

ARTICLE 2. ADJUSTMENTS TO THE SHARES.

                  2.1 Stock Dividends, Splits, Etc. If the Company declares or
pays a dividend on the Shares payable in common stock, or other securities, then
upon exercise of this Warrant, for each Share acquired, Holder shall receive,
without cost to Holder, the total number and kind of securities to which Holder
would have been entitled had Holder owned the Shares of record as of the date
the dividend occurred. If the Company subdivides the Shares by reclassification
or otherwise into a greater number of shares or takes any other action which
increase the amount of stock into which the Shares are convertible, the number
of shares purchasable hereunder shall be proportionately increased and the
Warrant Price shall be proportionately decreased. If the outstanding shares are
combined or consolidated, by reclassification or otherwise, into a lesser number
of shares, the Warrant Price shall be proportionately increased and the number
of Shares shall be proportionately decreased.

                  2.2 Reclassification, Exchange, Combinations or Substitution.
Upon any reclassification, exchange, substitution, or other event that results
in a change of the number and/or class of the securities issuable upon exercise
or conversion of this Warrant, Holder shall be entitled to receive, upon
exercise or conversion of this Warrant, the number and kind of securities and
property that Holder would have received for the Shares if this Warrant had been
exercised immediately before such reclassification, exchange, substitution, or
other event. The Company or its successor shall promptly issue to Holder an
amendment to this Warrant setting forth the number and kind of such new
securities or other property issuable upon exercise or conversion of this
Warrant as a result of such reclassification, exchange, substitution or other
event that results in a change of the number and/or class of securities issuable
upon exercise or conversion of this Warrant. The amendment to this Warrant shall
provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article 2 including, without
limitation, adjustments to the Warrant Price and to the number of securities or
property issuable upon exercise of the new Warrant. The provisions of this
Article 2.2 shall similarly apply to successive reclassifications, exchanges,
substitutions, or other events.

                  2.3 [reserved]

                                       3
<PAGE>

                  2.4 No Impairment. The Company shall not, by amendment of its
Articles or Certificate (as applicable) of Incorporation or through a
reorganization, transfer of assets, consolidation, merger, dissolution, issue,
or sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed under
this Warrant by the Company, but shall at all times in good faith assist in
carrying out of all the provisions of this Article 2 and in taking all such
action as may be necessary or appropriate to protect Holder's rights under this
Article against impairment.

                  2.5 Fractional Shares. No fractional Shares shall be issuable
upon exercise or conversion of the Warrant and the number of Shares to be issued
shall be rounded down to the nearest whole Share. If a fractional share interest
arises upon any exercise or conversion of the Warrant, the Company shall
eliminate such fractional share interest by paying Holder the amount computed by
multiplying the fractional interest by the fair market value of a full Share (as
determined in accordance with Section 1.3).

                  2.6 Certificate as to Adjustments. Upon each adjustment of the
Warrant Price, the Company shall promptly notify Holder in writing, and, at the
Company's expense, promptly compute such adjustment, and furnish Holder with a
certificate of its Chief Financial Officer setting forth such adjustment and the
facts upon which such adjustment is based. The Company shall, upon written
request, furnish Holder a certificate setting forth the Warrant Price in effect
upon the date thereof and the series of adjustments leading to such Warrant
Price.

ARTICLE 3. REPRESENTATIONS AND COVENANTS OF THE COMPANY.

                  3.1 Representations and Warranties. The Company represents and
warrants to the Holder as follows:

                           (a) [reserved]

                           (b) All Shares which may be issued upon the exercise
of the purchase right represented by this Warrant, and all securities, if any,
issuable upon conversion of the Shares, shall, upon issuance, be duly
authorized, validly issued, fully paid and nonassessable, and free of any liens
and encumbrances except for restrictions on transfer provided for herein or
under applicable federal and state securities laws.

                           (c) [reserved]

                  3.2 Notice of Certain Events. If the Company proposes at any
time (a) to declare any dividend or distribution upon any of its stock, whether
in cash, property, stock, or other securities and whether or not a regular cash
dividend; (b) to offer for sale additional shares of any class or series of the
Company's stock; (c) to effect any reclassification or recapitalization of any
of its stock; (d) to merge or consolidate with or into any other corporation, or
sell, lease, license, or convey all or substantially all of its assets, or to
liquidate, dissolve or wind up; or (e) offer holders of registration rights the
opportunity to participate in an underwritten public offering of the company's
securities for cash, then, in connection with each such event, the Company shall
give Holder: (1) the same notice as is given to the other securitiesholders of
the Company of the date on which a record will be taken for such dividend,
distribution, or subscription rights (and specifying the date on which the
holders of common stock will be entitled thereto) or for determining rights to
vote, if any, in respect of the matters referred to in (c) and (d) above; (2) in
the case of the matters referred to in (c) and (d) above, the same notice as is
given to the other securitiesholders of the Company of the date when the same
will take place (and specifying the date on which the holders of common stock
will be entitled to exchange their common stock for securities or other property
deliverable upon the occurrence of

                                       4
<PAGE>

such event); and (3) in the case of the matter referred to in (e) above, the
same notice as is given to the other securitiesholders of the Company.

                  3.3 [Intentionally Omitted]

                  3.4 No Stockholder Rights. Except as provided in this Warrant,
the Holder will not have any rights as a stockholder of the Company until the
exercise of this Warrant.

ARTICLE 4. REPRESENTATIONS, WARRANTIES OF THE HOLDER.  The Holder represents and
warrants to the Company as follows:

                 4.1 Purchase for Own Account. This Warrant and the securities
to be acquired upon exercise of this Warrant by the Holder will be acquired for
investment for the Holder's account, not as a nominee or agent, and not with a
view to the public resale or distribution within the meaning of the Act. Holder
also represents that the Holder has not been formed for the specific purpose of
acquiring this Warrant or the Shares.

                 4.2 Disclosure of Information. The Holder has received or has
had full access to all the information it considers necessary or appropriate to
make an informed investment decision with respect to the acquisition of this
Warrant and its underlying securities. The Holder further has had an opportunity
to ask questions and receive answers from the Company regarding the terms and
conditions of the offering of this Warrant and its underlying securities and to
obtain additional information (to the extent the Company possessed such
information or could acquire it without unreasonable effort or expense)
necessary to verify any information furnished to the Holder or to which the
Holder has access.

                 4.3 Investment Experience. The Holder understands that the
purchase of this Warrant and its underlying securities involves substantial
risk. The Holder has experience as an investor in securities of companies in the
development stage and acknowledges that the Holder can bear the economic risk of
such Holder's investment in this Warrant and its underlying securities and has
such knowledge and experience in financial or business matters that the Holder
is capable of evaluating the merits and risks of its investment in this Warrant
and its underlying securities and/or has a preexisting personal or business
relationship with the Company and certain of its officers, directors or
controlling persons of a nature and duration that enables the Holder to be aware
of the character, business acumen and financial circumstances of such persons.

                  4.4 Accredited Investor Status. The Holder is an "accredited
investor" within the meaning of Regulation D promulgated under the Act.

                  4.5 The Act. The Holder understands that this Warrant and the
Shares issuable upon exercise or conversion hereof have not been registered
under the Act in reliance upon a specific exemption therefrom, which exemption
depends upon, among other things, the bona fide nature of the Holder's
investment intent as expressed herein. The Holder understands that this Warrant
and the Shares issued upon any exercise or conversion hereof must be held
indefinitely unless subsequently registered under the 1933 Act and qualified
under applicable state securities laws, or unless exemption from such
registration and qualification are otherwise available.

ARTICLE 5. MISCELLANEOUS.

                                       5
<PAGE>

                  5.1 Term: This Warrant is exercisable in whole or in part at
any time and from time to time on or before the Expiration Date.

                  5.2 Legends. This Warrant and the Shares (and the securities
issuable, directly or indirectly, upon conversion of the Shares, if any) shall
be imprinted with a legend in substantially the following form:

                  THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN
                  REGISTERED UNDER THE ACT, OR THE SECURITIES LAWS OF ANY STATE
                  AND, EXCEPT AND PURSUANT TO THE PROVISIONS OF ARTICLE 5 BELOW,
                  MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR
                  HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER SAID ACT AND
                  APPLICABLE STATE SECURITIES LAW OR, IN THE OPINION OF LEGAL
                  COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER OF
                  THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR
                  HYPOTHECATION IS EXEMPT FROM REGISTRATION.

                  5.3 Compliance with Securities Laws on Transfer. This Warrant
and the Shares issuable upon exercise of this Warrant (and the securities
issuable, directly or indirectly, upon conversion of the Shares, if any) may not
be transferred or assigned in whole or in part without compliance with
applicable federal and state securities laws by the transferor and the
transferee (including, without limitation, the delivery of investment
representation letters and legal opinions reasonably satisfactory to the
Company, as reasonably requested by the Company). The Company shall not require
Holder to provide an opinion of counsel if the transfer is to Silicon Valley
Bancshares (Holder's parent company) or any other affiliate of Holder.
Additionally, the Company shall also not require an opinion of counsel if there
is no material question as to the availability of current information as
referenced in Rule 144(c), Holder represents that it has complied with Rule
144(d) and (e) in reasonable detail, the selling broker represents that it has
complied with Rule 144(f), and the Company is provided with a copy of Holder's
notice of proposed sale.

                  5.4 Transfer Procedure. Upon receipt by Holder of the executed
Warrant, Holder will transfer all of this Warrant to Silicon Valley Bancshares,
Holder's parent company, by execution of an Assignment substantially in the form
of Appendix 2. Subject to the provisions of Article 5.3 and upon providing
Company with written notice, Silicon Valley Bancshares and any subsequent Holder
may transfer all or part of this Warrant or the Shares issuable upon exercise of
this Warrant (or the Shares issuable directly or indirectly, upon conversion of
the Shares, if any) to any transferee, provided, however, in connection with any
such transfer, Silicon Valley Bancshares or any subsequent Holder will give the
Company notice of the portion of the Warrant being transferred with the name,
address and taxpayer identification number of the transferee and Holder will
surrender this Warrant to the Company for reissuance to the transferee(s) (and
Holder if applicable). The Company may refuse to transfer this Warrant or the
Shares to any person who directly competes with the Company, unless, in either
case, the stock of the Company is publicly traded.

                  5.5 Notices. All notices and other communications from the
Company to the Holder, or vice versa, shall be deemed delivered and effective
when given personally or mailed by first-class registered or certified mail,
postage prepaid, at such address as may have been furnished to the Company or
the Holder, as the case may (or on the first business day after transmission by
facsimile) be, in writing by the Company or such holder from time to time.
Effective upon receipt of the fully executed Warrant and the initial transfer
described in Article
